"Day 1 of the Easiest CCNA CCNP Program for Network Engineers!"

okay so let me share my screen guys now and we are ready to start yeah so type yes if you guys can see my screen okay great okay okay so good news uh we are going to learn the latest uh CN CNP okay so Cisco has recently changed the content and uh see CCNA has no change okay CCNA change CCNA is still 200301 is the exam code okay so CCNA is a first level exam so basically this batch I hope everybody knows this is a combination of CCNA certification plus it is a combination of ccnp NRC okay so this is one of the exams of ccnp so there is another exam also in core which you guys can join in future okay but right now we are covering and uh this CCNA plus 300410 NRC and this is the latest uh NRC version 1.1 we are going to cover okay so so whenever you check any content okay so normally uh if you go to Cisco website like if you can see exam topics so what is CN CN is certification okay so what we are learning here as certification exam topics to prepare and get the certification of CCNA so if it's your choice you want to give CCN exam or not but CCNA certificate uh uh let me show you recently I think one of my student got certified day before yesterday uh yeah so this is the link I think yeah so this guy got certified four five days back okay from yeah so you can see this is what we call CCNA certification okay and when you get certified you can also mention us uh maybe me or maybe you can both networking s Atul Sharma so that uh this is actually our reward that when student get certified they mention our name when they get jobs they mention our names okay so this is how you will get certified like uh Adil got certified few days back and there are a lot of other students also they keep doing uh like certification exams and all okay so this is uh uh I wanted to tell you and another thing so when you give the NRC exam you will also get one certificate okay let me show you that also I think uh let me show you on Google because if I have to find my student then it will take time okay but when you give an RC exam okay so you will get a specialist certification Okay so it means in this in this uh course we are going to learn two courses one is CCNA one is ccnp andrc which is called but when you an just hold on I'm getting my will get a specialist okay it means in this yeah coming back to that link yeah so this is the certification you will get Cisco certification special specialist Enterprise Advance infrastructure implementation okay so I hope everybody has a goal to become certified right how many of you want to give certification exam yeah most of you right yes you guys can put down in the chat yes no need to write sir just say yes else it will take time okay great okay so uh lot of chances to get certified certification because if you learn properly and if you prepare for questions and this like exam comes with Labs also before a few years like it was completely McQ question but now like it is like a proper quiz where you have to do McQ quiz okay so for example if I show you CCNA quiz McQ uh so it is like all McQ questions like this okay so this is one of the how the exam going to be so the first thing they have multiple choice single answer m multiple choice multiple answers drag and drop fill in the blank simulation and some test lit okay so this is the first type of question I hope this is everybody knows that this is going to be a little blurry image okay I hope you will see the blur also but there are multiple option you have to take multiple options from that okay so this is going to be kind of one question this is called multiple choice question some questions have one answer some questions have two answers so the second type of question is called drag and drop you have to drag the fill up fill and fill in the blanks you can say so just you have to drag and drop on the right answer this is what we call drag and drop questions the these type of questions will also come in exam okay uh fill in the blanks are not in cesco exam so ignore that and one is called simulation what is called simulation there will be a lab okay so you have to do some configuration right now I think in C CNP two three labs are coming if you clear those labs you get more points okay so the total exam of CCN is around 1,000 marks and NRC is also 1,000 marks but if you check the passing score and all it is around 825 okay so it is obviously more than 80% but yes normally people get 90% 95% and we have almost 100% success rate if you learn properly if you learn properly if you prepare for the exam properly you will definitely get certified okay so an RC also as I mentioned if you clear an RC you will also get a certificate which is called Cisco certified specialist and I think one exam also has very good value in the market uh it is your call if you want to give an core there is another brother of this exam which is called ccnp Encore okay that batch after this batch I will start my Encore batch also okay and uh if you do not want to waste time because this is only Monday Tuesday class if you have time you can separate after CC topics you can join and core separately from other trainers also okay if you want to join with me complete this batch then we will start in core also okay so as I mentioned there will be McQ question there will be drag and drop questions there will be simulation Labs exam lab questions okay so this is going to be three types of questions normally multiple choice single answer answer answer some questions have single answer multiple answer drag and drop and simulation four type of questions will come in exam okay and CCNA certification is very old certification okay so CCNA started I think in 9798 I think CN first certification year something I think it's 1998 so it's almost 25 years guys certification 25 years down the line so if somebody is saying there is no value of network Engineers just show them this thing okay 1998 that if anything is running from last 25 years obviously uh still the networking is growing day by day okay so uh some people who are average they always uh find negativity in everything even if if anybody wants to say negative about anything they can find negative about any any good thing right I hope you understand so uh everybody just don't listen to them just it's simple is that just focus on your career okay because somehow down the line if you love how to make career just if you feel like yes you are able to learn then it's good okay so let me tell you one more thing so so this batch is going to be like I have arranged in such a way okay so you can see here at back of my side learn practice and apply okay so this going to be the uh plan for this batch you are going to learn live classes then you are going to do practice labs and then you are going to apply those skills in your resume are you getting my point guys okay so let me show you okay so I've have prepared Excel sheet for all of you okay uh but yes this is not the final I will keep ated because I got little less time to prepare for that but yes uh I made this sheet called world best network engineer okay so we are going to learn all these classes live okay some topics I'll give you video also if uh you get are okay obviously okay so these are going to be the topics like it is like combo batch CCNA plus ccnp and RC so if you only want to join an RC uh maybe in November end I will start uh that batch okay but um before that I'll be covering the basics okay and this batch is going to be the super easy batch even if I'm doing live streaming you can see even I have given the title for this batch is day one of the easiest CNS CNP program for Network Engineers so I'll make sure the topic you learn in such a way that it is going to be very very easy for you okay e okay but don't worry if I'm saying easy it does not mean we will not cover in detail we will obviously cover in detail everything okay but it's just uh my Approach of delivering this batch is going to be I will consider you all very beginners okay is that fine guys or should I consider you experts if you are already experts then why you are here okay so experts are basically the people who are very good at Basics those are experts right so experts are not people who are CCI who is like Double C say Triple C say no the experts are real experts who are very very good at Basics okay trust me when I joined Juniper Networks when I was with apple okay so in those companies I've seen people don't have CCI they do not have certifications they don't have ccnp certification they don't have CCI but the people who are under them they are CCIS they are ccnp means it is not always that certification will show you the right uh they will give you the higher positions no certifications are boosters okay booster if you have certification maybe it will help you in a job it will help you in career it will just for the uh changing jobs okay but if you are very happy with where you are working I'm sure many of you are very happy with where are you working okay so if you're happily working in any company maybe in XYZ so then no need to do certification okay so just learn the things and no need to spend money in your certification but yes if companies paying you because lot of companies are giving reimbursement okay so just check with your manager that I'm going to give CNS CNP exams in future like in four five months uh shall uh I apply for the certifications or will you reimburse my amount or not okay so just try because I was with the TCS and where we always get coupons for exams okay socl also has some in some projects they have okay so this is the sheet I'll share with all of you okay so where I have mentioned here that see learn live live means that whenever you have any question we can discuss in between the class or end of the class okay but we are going to learn live plus obviously you will be getting recordings as I mentioned okay so learn revise okay or I would say revise okay so recordings means revise and second is practice Labs because I have seen lot of people they join batches but they don't do practice okay so this time we will try to take uh some uh practice sessions like I'll be giving you some small topics homework and you guys can then maybe show uh maybe with some screenshots maybe with some portal I'll try to figure it out how we will do it but we will apply this rule as I mentioned learn practice and apply okay because last many batches I've taken they were just learning and doing Labs but people are not applying things in their resume so if you learn anything if you do not add in your resume then or maybe if you do not add in your profile in LinkedIn or somewhere then there is no use of learning that technology yes or no yeah right so goal the goal is to add all those skills in your resume okay add all these skills in your resume okay so so this is the topic as I mentioned and uh recently as I mentioned that we are going to learn the latest things even uh I bought an uh ccnp latest guide also okay so I'm just showing you it's not required right now because you guys are beginner but you can see this is the PDF I bought uh ccnp Enterprise Advanced routing and RC second edition so this is exclusive content for all of you and those who are my old students if they are watching on YouTube don't worry you will get update okay so do you know one good thing about networking uh like every year uh so we give all the students one year video access okay so that every year you renew them with latest content are you getting my point so it is not very big amount it is like, 2,000 Rupees only but if you pay that amount you will get the latest content now the people who attended my NC last year suppose last year NC so if they renew their NRC content they will give they will getting this batch videos so next year if there will be new update you will also get that new update also isn't it cool cancel okay so because technology is changing day by day and if you are not getting updated content then what is the benefit you just spent amount you learn the technology and after few years that technology becomes outdated right what if you just pay a small amount so that we get renewal so that we will be able to pay our hosting bills okay video hosting bills so uh you just get the latest content okay so this is all about CCN and RC guys I hope do you have any questions regarding before starting this batch any question you can type in the chat or if people are watching on YouTube can also ask okay so the all the topics are see in my Excel sheet you will always find more topics than Cisco okay so but yes now it is your choice you want to learn only only following the Cisco curriculum okay okay let's learn line by line if you want that I can deliver that also okay but line by line like you will feel little boring because if I do not add my industry knowledge okay if I don't add my knowledge in this curriculum then there is no benefit okay so that's why I made this Excel sheet so that I can show you okay so where we will be learning from very basic okay so that we go for the advanced topics like eagp and this all content this all content is directly I'm the only one who is covering directly from the books trust me okay so because I don't want to miss anything but uh if you check live courses I'm not talking about video courses live courses the most lengthy programs uh anywhere in the world right now I I have the longest batches because I deliver more than 150 hours of training okay uh Gotham has a doubt I have a doubt that I have gone through the lab portal to try something to create okay so Gotham actually see the labs trust me the labs you are getting at very very affordable prices okay first of all because we are not charging separately for that but if you try to uh check the lab access outside okay I'm just showing you so that you actually get the value okay so if you only go for the lab okay suppose uh we are using at the back end we are using some software which is called E and all but we have done some lot of customization okay so this is like monthly pricing so I'm just showing you that uh you have to pay 160 because we have more than 32 GB of RAM obviously we have bigger servers so lab $160 and this batch will run for four to five months and we are giving you six months lab access okay so $960 so this cost you are not paying to us the lab access you are getting is worth 80,000 if you if you actually go and buy the lab access separately like there is a website like cloudy.com okay so there are other companies I'm just showing you the prices so that you get an idea okay I'm getting that benefit okay so that's the whole plan so you will be getting this lab access and this is for 24 by7 No Limit you can do four hours 5 hours a day 10 hours a day that's your choice and if you get any problem as I mentioned earlier you have to go to our website okay go to contact us page and if you get any problem there is a WhatsApp number of support team you can click here and WhatsApp support team are you getting my point directly we have given we we do not ask people to do Emil because earlier I feel like if we are taking admission on WhatsApp then why not to give support on WhatsApp yeah WhatsApp okay but timings are normally 10:00 a.m. to that 600 p.m. so try to share your issue in morning time because if you are typing in 10 p.m. 11:00 p.m. currently it's we are not 24 by7 support but in future yes if many many more students have problem we will run 24x7 Support also okay take or quick question okay so as I mentioned lab access there are lot of labs lot of labs in one course you are getting lot of labs here okay and if you want any customization Suppose there is a lab okay so you want me to add like 10 routers more because what happen if you if we give you admin access if we give all Student Admin access they will delete all the labs or maybe they will create problem for our server okay so you have student access means you can open any lab you can do any practical see this big lab guys just see this lab Lab see yeah so these type of big big labs are already there in the portal you can go and start any of the labs without any problem you can see start nodes and trust me if you want to do this lab in your computer you need 64 GB plus Ram mean 32 but 32 GB laptop will cost you a lot right 32 GB laptop appro 2 laks in India okay so there are lot of labs but in case if you have any spe specific requirement okay if you have any suppose you want to make your company Network in our server okay so then what you can do this same software I will help you to install in your laptop also are you getting because the big already we have 200 300 plus slabs okay but if you want to do your customization I will help you to install this type of uh not the same one but similar software which is called EV okay because in we are not using proper even we have done our customization also okay so but yes at the back end somehow this software is called E where you can download this in your computer and you can do customization according to that but if your laptop is not capable of doing big Labs you can share that topology because see if you want to do this type of big lab but your computer is not able to run that big lab so so you can go here you can see there is a option called export export yes guys so you have to just share make your topology in your computer okay but don't do practicals in your computer if your computer do not support High Ram okay or not support basically if your computer do not able to do the Practical like bigger ones as I mentioned okay so those labs you can just share export to the support team as I mentioned and they will be adding those they will be adding those labs in our server it will save your time customization option like obviously we can't give you that admin access of this portal so that's why the easiest way you can create your Labs on your computer share with us we will upload here okay but you can do all these 200 plus labs and there are a lot of labs you can't complete in this batch trust me okay so I hope the question is clear yes raakesh you can join language create barrier yeah simple English is mandatory bro so whenever you feel like this topic I'm not able to understand you can type in the chat sir can you please explain in Hindi I will do it for you but only in the complex topics not in very basic topics okay clear sir if we use this Labs then we need to give IP on these manually yes yes everything is manually these are blank routers so what is troubleshooting will the problem if you fix the problem that's called troubleshooting okay okay so let's start that class guys so today is like basic as I mentioned so we have already created our own networking book so initially we will follow this cont don't worry about the content okay so as I mentioned this is the first book you will be getting please join the WhatsApp Channel what I have created okay so that you do not miss the content uh because on email uh people don't read emails but WhatsApp somehow everyone see right so we will upload in the portal also so what is Portal where we upload videos if you miss the class Anand you can proceed with the course you can just contact team and take admission okay so there is a WhatsApp number on YouTube also we have mentioned okay so just uh anybody can take admission in this batch if anybody joined as a demo we I don't feel like there is a demo student here I think everybody's enrolled right so guys uh you all are enrolled or just you are here for demo I'm just asking if you are enrolled raise hand okay mostly enrolled people joined okay turn on cameras and okay lot of students okay great okay okay great great great icon they don't have the camera maybe or they feel shy don't worry guys we all are H take take good good okay so let's start the topic and this book you'll be getting today and it is very very simple book as I mentioned we are going to learn very very easily okay easy mov Muna meun okay so let's open screen brush so this is a tool I use to write on [Music] screen okay great guys uh please verify if you guys can see everything what I'm doing right now so I've highlighted the CCNA you guys can see okay just hold on I think okay not for this badge I don't know okay screen yes guys everybody can see my screen okay so let's start okay so this is I've already mentioned myself I have more than 10 plus years of experience you guys can read uh in this book later on but let's study now okay so CCNA so right now ysso is popular uh because this Cisco has almost 80% of the market 80% of routing switching devices are used by companies from Cisco that's why Cisco courses are more more popular okay this is the first uh benefit after that okay so basic of networking so what is basic of networking means uh we are going to cover very very basic of networking Okay so so what is Network as in the previous class we discussed okay so if like two routers you want to connect okay or two computers you want to connect so all these this is an example of network okay if you connect multiple more devices so when you connect multiple computers that is called Network I'm not audible one guy is saying I'm not audible I don't know why okay clear okay so what is network network is just a collection of network devices and end system connected to each other to network what is Network combination connecting multiple devices together like if you have four computers okay so when you connect four computers together so that is also example of networking Okay so and like what are these network devices like computers servers smartphones routers so these are examples of your network devices okay to network a network could be a bigger bigger Network called internet so the big network is called internet okay so what is internet lot of different different networks are combined together lot of networks are combined together that's called internet okay suppose your home network my college network okay so lot of lot of places are connected together okay so when they connect with each other that's like they become what internet so when all these locations are connected together they they are called internet like network of networks is known as internet okay what is internet [Music] Network okay I have some problem in writing here uh no worries okay so network of networks so what what is internet when somebody ask you okay can you nobody will ask you in very good interviews but in simple interviews if anybody ask okay can you explain internet so you can simply say that network of networks is called internet because this is my home network this is your college network this is my office Network this is your office so lot of companies colleges universities everybody hospitals everyone is connected and they all are different different Networks like every company every office everyone has a different network and when we combine all these networks together that's called internet so means network of networks or network of different different networks is called internet clear yeah very simple right so now if we check here lot of network devices are there in the market okay like computers okay so one of the devices are called computers everybody knows what are computer they are normal computer systems which connect to network and send and receive data like your phones right now so right now your phone is sending data and receiving data right the same way computer laptops these are personal computers these are called PCS right I don't have to explain PC right so now when we talk about NIC card what is NI so Nic is a chip basically Nic is a chip NIC card is a chip you can add that chip inside your laptop or computer but nowadays this chip is already inbuilt in laptops inside all these laptops nowadays they already have Nic cards okay all these have Nic cards so n ni full form is network interface card okay so normally one computer suppose this is a laptop so laptop already has a inbuilt NIC so which is called network interface card and this Nic has Mac address okay so there is no Mac address of any computer by the way technically okay so there is no Mac address of any computer the MAC address is on on Nic chip if computer has Nic then computer has Mac address but if computer do not have Nic computer do not have mac address clear yes Stan okay okay so Nic will discuss more okay but Nic has a MAC address that is assigned by manufacturer manufacturer means any any company who create an i chips they give a MAC address to people or to the machines okay so then we have network cables and connectors so like for example in this scenario okay so see here so you can see here like computers are connected together it is just a diagram but normally in real world computers will be connected with some cables right or maybe with Wi-Fi okay so the these These are called cables and connectors which will help you to connect with the network okay or it can be Wireless also like in your company maybe you are using a laptop with cable for internet which is called Lan cable okay and maybe your company has Wireless okay totally depends but which is more reliable guys tell me wire or Wireless right now okay wi not weird basically wide okay so wide connections are more reliable because Wireless can create any problem maybe if you go a little far away signal will drop right wi connectivity is more more reliable that's why but nowadays Wi-Fi is also getting stronger and stronger day by day but if you get a chance if you want to play a movie okay in your television like in Smart TV so will you use cables or Wi-Fi is okay Wi-Fi is okay right because if any movie is like little blurry you will handle it if your network is not stable you feel it's okay but in a company if a very very important meeting going on so would you able to take a chance to uh like if video meeting gets blurred will you take chance so now tell me wide right so that's why in your in your meeting rooms if you have if you are already working in meeting rooms mostly we also have land cables yes or no yes we also have landpoint normally we feel like lazy I know that we can do meeting with wireless but normally we have Lan cables also why because we do not want to take a risk if network is not stable then there would be a problem right so that's why wi connectivity is more reliable okay Wireless is okay okay but I don't say not reliable but not reliable as wide connections okay not reliable as wide Wireless is also good there is no complain even right now I'm using Wireless meeting going on but I'm on wireless because I can if you feel like uh the screen is not good or something because I'm sitting very next to Wi-Fi and there are not other employees or uh my other family members are not connected to this wi-fi okay so what is host a computer laptop printer any device you call host to host what is host a host can be laptop computer mobile enter any device that uses IP address to go to internet is called host okay very basic let's go further if you read this line by line you will not feel like any problem because this is so so easy okay if I show you all big Cisco books and all it is like we little complex language is a little complex to understand because it's purely written in such a way that it looks like uh what we call the big guide right okay so now in networking whenever you see a diagram that's called topology okay suppose if there is a picture here two routers are connected okay let me show you a topology uh okay so let me change uh my background okay let me Spotlight uh you guys can see me right H take okay so you guys can see behind me you guys can can see a picture right yeah so what is this basically this design like if you see on the top there are some routers and all okay so what is this picture this picture diagram you will not say okay let's take a pledge we will not say this is a picture now this is not a diagram we can say that it's a network diagram but not diagram so what we call this this whole back side this is what we call topology yeah topology okay so now what topology is this guys this is physical topology or logical topology what do you see yes is a physical physical topology okay and not physical this is logical Okay so physical is basically when you actually see the devices what we call server room server room server room and all these where actually we place network devices and all those are called those are called your what we call physical topology basically like how the actually networking is going on at the back side if I try to show you my camera is little blurry today I don't know why I try to make it more engaging yeah so now you can see this whole picture at back side so this is what we call physical infra physical infrastructure you can see all these cables are added here right at the back side so all these are called how actually devices are connected so this is called physical topology okay the previous one when you see routers with icons okay those those icons and all these are called so now tell me which topology is this type in the chat yeah con topology this is called physical topology or we can say that it's a physical connectivity okay physical connectivity physical devices when you actually see the network devices in your office that's called physical connectivity and all and when you have uh what we call the diagrams okay what we call okay these are called logical topologies because we are going to see how the cables are added how these two routers R1 P1 P2 are connected right all these are going to be like that okay great now you got the idea okay now we got the idea so we have two topologies so as I mentioned one we have logical and one we have physical okay so this diagram when you actually make icons icons when we add circles when we add rectangles all these things are called logical topology okay but when we see the real topology is called physical topology okay physical topology so now if we talk about about topologies so there are different different type of topologies in the market okay so if I show you okay so this is just a small video I'll be playing and going to explain because this is in Hindi uh so I'll translate this in English for you so this just it's a 3 minutes let's play so this is like Network topologies okay so what is Network topologies so there are few few designs actually how we can add router network devices in our company okay so the first topology is is called bus topology okay where this is very very old design guys where we have one cable and you connect all computers with that cable this is called bus topology C we have only one cable and where we add all the computers with one cable so tell me if one cable goes down what will happen all my company network will go down yes or no yes agree CH yes network will go down this is the problem that's why we do not use this topology now yes do we use if I ask you question do we use bus topology now no okay so ignore this now bu we just want to know okay this is a topology very old dated outdated we do not use bust apology now after you can see we are sending data and if one cable goes down let me show you if cable will go down or not I think we have added it see data is going but if cable goes down right what will happen the whole devices they will not get data right this is a problem we are not using see sometimes we have to go to the back side right right why we are learning this so that you get an idea why what are topologies right simple Cisco want you to understand these okay so so bus means they are just traveling if one uh link goes down so the other topology is called star topology this is the mostly used topology because star means you connect a network device called switch and when you connect cables with that switch when you actually connect computers with a network switch is called star topology because you can place all computers anywhere I don't know why they call Star but yes uh you can add multiple connections together that's called it is star topology clear everyone okay so this is called star and this is the most commonly used topology everywhere now tell me uh if you go to your office if you use laptop ignore Wireless if you connect landan cables so what topology you guys are using in your company now bus or Star mostly everyone is using star one guy is saying bus I think he is not enrolled because he can't dare to enjoy my classes like this we are using bu apology in my company actually he's talking about he goes to office with bus okay so this is the bus topology okay so now if we go further okay so if we go further I think uh we have lot of lot of companies are using star topology then we have mesh topology mesh means like computers connect with each other with all the cables but this is very very costly but understand because how many computer uh how many ports Lan ports you have in your computer normally one and nowadays all laptops they even don't have like if you buy Mi redmi all these lapt they don't have even single port even MacBook also do not have this ethernet port chindi companies okay so these companies don't have the land ports okay but now try to understand this partial mes mesh means you connect your computers with each other so do you find this is relevant nowadays because do you buy three three Lan ports for your laptop so we do not use partial mesh but if we consider if we are now consider these laptops are my office routers this is Dilly Mumbai Chennai Kolkata four offices so do you think now partial mesh is okay office if you have four offices Delhi Mumbai Chennai Kolkata so then it is in the van connectivity wide area network which means okay if you have multiple offices then we can connect like this right right if you are a big company obviously yes you can use that right you can connect dly to Mumbai Mumbai to Chennai Chennai to Kolkata right to you partial mesh mesh topologies are not used in Lan networks partial mesh can be used in Van networks when you connect routers with each other not computers if you do not understand don't worry we will cover in further classes how when you understand what is router why router connect with multiple routers and all but try to understand in Lan networks Lan means local area network okay your home network is also Land network your office network is also Land network when okay so any small Network okay within the uh area that's called L Network you can say even a company network is called Lan if you are at same location okay so now partial mesh means but in Land network we do not use because it's very very costly okay so we have partial mesh also instead of what is full mesh you connect all computers with each other that's called Full mesh okay which is very costly and we have partial mesh where uh you connect just few three four links with each other but not all links okay so this is what we call full mesh and part partial partial has like three four links like this this is partial mesh because the this uh second computer and the fourth computer is not connected because they are connected with first and this one third right so this is called partial means there are not all computers are not connected to each other means you have lot of links but not all computers are connected to each other that's called partial but when all computers are connect to each other that's called Full mesh clear everyone great okay so there is a Formula how many links are required like if there is a example like n n minus 1 is equal to 2 suppose you have five computers okay put five here little bit math not too much so suppose you have five computers for five 5 - 1 4 5 into 4 20 20 ided 2 is 10 so for five computers how many links are required 10 links because you connect lot of links now the total links is like okay so this is just example if you have seven let's take seven 7 7 - 1 6 76 42 42 divided 2 is 21 links C 21 cables are required if you have seven computers in full mesh so this is very very uh outdated I would say because everybody uses star topology switches use mostly use switches and there is very another very old topology this is also called ring topology like a ring you can see the data will come to you one by one okay it is like a ring okay but normally we do not use a ring also in the Lan networks but this ring is also used in ISP networks if you join AEL if you join Reliance if you join any ISP what is ISP internet service provider internet service provider but ISP big companies are using uh means they're connecting their routers this is like example of big router so they are connecting their big routers in a ring okay like you can see all these routers are connected together and they are forming ring networks so this is very Advanced for you all okay but yes big companies are using ring networks where they put routers connected with each other okay that's called ring Network okay so uh used by ISP nowadays okay so normally what we learn from this topologies we have bus topology star topology partial mesh full mesh and then I told you that's what we call ring topology so only nor mostly we use which topology star because all other topologies if we use they are going to be very very costly for us if you see the bus topology this is very it's a big problem if one cable goes down the whole company network will go down that's why do not use bus topology okay then we have star topology where If one computer goes down there will be no effect on other computers that's why it is best of the best network okay and after that we have this called partial partial will be very costly for you you can add computers but you need lot of links lot of links you will not connect with each other in the Lan Network right so will you go to your office man management and say sir we have 50 laptops and every laptops need four landport so will you buy 200 Nick cards separately after buying laptops to do land man yeah gorav is saying manager will say put the papers give resignation if you have that Solutions as a network engineer okay so ring networks we use in ISP okay so if you are from working with ISP I'm sure you know that ISP networks are on ring networks okay so big companies are using ring topologies again it's a costly solution but big companies need redundancy means they need connectivity that's why okay so watch this video I'll be sharing this link in your chat okay whenever share any Link in the chat try to save okay or just write uh topologies on our YouTube channel you will get it okay okay so let's uh uh watch this also as a network devices okay another five minutes okay so what is Nic what I told you so Nic is this chip called network interface cards guys is my voice cracking I don't feel like uh I think the student has issue from his side okay so NIC card what is Nic so Nic stands for network interface card and long time back 10 years 15 years back so every computer like in every computer we have to buy separately this NIC card which we add in the PCI slots okay it's a chip basically you can see the and we have to place this in the PCI slot this is what we call PCA slot this is motherboard we have to add like this this is very very old like 10 years 15 years back okay but nowadays all the motherboards and computer don't have mac address computer do not have any Mac address okay but where we have mac address we have mac address on this chip okay we have mac address on this chip and nowadays all the motherboards already have this chip inside you can see some slots yes guys you can see right so these Nic cards are already inbuilt on mother board so you do not have to buy separately now so after this video I'll give you five minutes break so this is what we call ethernet port also Lan Port ethernet port okay ethernet port would be more good term okay so nowadays we have two cards three cards depends on your motherboard you have multiple ports also so these are called Nic cards okay so these are called Nic chips so moving on so after that if we want to connect four computers together okay so then we buy a device which is called switch okay or Hub earlier it was Hub but Hub has a problem if you send data to one computer data will go to all computers so Hub we do not use nowadays there will we Hub is obsolete device we do not use Hub because it waste a lot of bandwidth because if I want to send you a file okay if one computer a want to send data to computer B the data will go to C also D Also let's see so in Hub we connect all computers you can see the cables are connected with computers like this okay so this is how we connect computers like eight computers together okay so it is not used anymore because if you send data you can see send data it will go to all computers together yes I'm sure if I if I show you again you can see the packet will go and will it will send to all the computers so this is what we call broadcast if you send data to everyone this is called broadcast if you send to one machine but go to everywhere that's called broadcast okay it's a problem because bandwidth utilization will go high okay so this is what two devices we covered Nic and hub yes so okay so then we bought a switch which is more powerful device okay where we connect all computers and there is no problem of broadcast if we replace this Hub if you replace this with switch basically so switch will only send to a computer to B only because switch learn Mac address that okay packet is coming from a computer is going to B so switch learn Mac address that's why it is going to the same computer so he's saying I the B computere please only send to me and other computers will reject the packet okay that's let me repeat again so switch the switch if you send data to switch switch learn Mac address that's why he know the location that's why do the switch do not have to forward packet to all computers but till the time we do not get MAC address we switch also do broadcast one time two time okay we'll discuss this in practical but which is more intell ENT Hub or switch tell me switch because why switch is more intelligent because switch learn Mac address okay switch learn Mac address that's why it is way better than okay so after that we have a device which is like the father of network devices okay router so basically if you want to connect two different networks because two different networks by default they cannot talk yes by default two different like uh internet is also different network right internet is also a different network so why you always need router in your home why everyone have Wi-Fi devices at home router what we call router Wi-Fi devices okay because all these devices connect with different network router what is router connect two different two or more different networks together this is how we build net internet lot of network devices routers are placed on internet every College University campus companies they all have routers and all these routers even big ISP big ISP also have routers this is how your data is going to Google and Facebook all routers are forward foring your data to Google Facebook anywhere because routers are forwarding your data they check routing table they check and forward data okay so everywhere every company Medical Hospital everyone everyone is using routers and these routers are helping us to connect with each other clear everyone so which cable we place between routers normally when Cable cable use which cable is used between routers normally van cable we can say that router is a van device but nowadays we can use in Lan also we'll discuss in practicals okay so what are van cables so some cables are under C obviously we can't put uh so big ISP they have lot of routers lot of routers and they have cables okay and they connect routers with cables obviously and these cables provide connections to home offices and all all these things clear okay what I recommend you guys I don't know why people don't watch it but we have lot of Animation content okay one video takes around 7 to eight days to create do you know how was the content tell me have you seen this type of content anywhere rarely you will find it okay so we are creating those content day by day that's why uh and we are uh so initially we created very basic content and basic knowledge we always give we put on YouTube it's uh like it's free obviously but now we started making premium content in animation also okay so now you can see try to go to a you YouTube channel try to check animation more videos okay so you will get some ideas about what is Ping what is bgp what is again TCP UDP OSP VPN okay try to watch these topics in free time okay is free time okay so let me type this link in your chat so that you can bookmark this link guys okay so there you will find those animation content okay so now coming back [Music] to okay so Network topology you understand you understand about star ring topology bus topology and all okay so like if you have mix of topologies that's called hybrid but this term we do not use too much okay so let's take a five minutes break and come back okay okay it's like watching movie like come back in 5 minutes okay I'm back guys sorry if I'm late uh please make English yeah I'm speaking in English only do you find feel like I'm speaking Chinese yes Rey uh okay shabas welcome to networking okay so coming back to huh so after that so what is unicast multicast and broadcast my screen is visible right okay so what is unicast means when you send data to only one computer that's called unicast okay so when you send data to everyone that's called broadcast and when you send multiple devices that's called multicast okay so let me show you unicast multicast broadcast okay so see this uh blurry picture I got a blur image from internet okay but you can see when you send data from one computer to one server one computer to one computer that's called unicast what we call this uni when we send data to everyone that's called broadcast not even a single device is left when you send to everyone broadcast and when you send to some multiple devices but not everyone that's called multicast okay so this is what we call and this is very going to be very very useful in our learning so because sometimes we say this is a broadcast this is a multicast so remember this so when we send data to one by one one to one is called unicast one to many is multicast one to all is called broadcast clear okay so network devices we know router is a device which connect different different network together so router is a networking device or inter networking device which is used to connect two or more diff this is going to be a definition if somebody ask you router what is router Router is a networking device used to connect two or more different networks clear everyone so which layer is this this is called layer three so we have not done yet OSI model but if you know a little bit of OSI model so Network layer this work on network layer we will discuss this OSI model very soon so what router does router sir what is the main work of router routing simple easy to remember what is the work of router routing what is routing forwarding of packets from one network to another Network forwarding of packets packet Network packets are normally it's a common term we use in networking forwarding of packets from my city to your city from my Facebook to your Facebook ID from my WhatsApp to your WhatsApp anything any application so when I forward data from one location to another location on internet okay so that forwarding of packets from one network to another network is called routing right so it it perform router is forwarding my data to the Internet so what router is doing router is doing routing so Hub we discuss Hub is a land device okay which works on physical layer Hub has very very less number of ports Hub is a dummy device because it simply broadcast the frame okay so there was a device called Bridge also okay so what is Bridge basically like when you have a lot of hub this bridge devices came before switch okay so like if you want to connect multiple computers or multiple hubs together uh if I talk about where we use Bridge yeah this picture is better not so better yeah so if you see this okay so you can see like computers are connected with Hub but Hub do not learn Mac address that's why we place bridge bridge learn Mac address but nowadays not we do not use Hub we do not use Bridges directly we have a device called switch because switch learn Mac address and switch also connect computers with each other okay but earlier days this is this is the design we connect computers with Hub then we connect hubs with Bridges because Bridge learn Mac address okay but nowadays combination of bridge and hub you it's like you can say that okay to HUB or Bridges combo The Hub and bridges are combined together and with some more intelligence we call them devices called switches okay so this is the another Advantage okay so what is Hub bridge and router okay so we have written a Blog I think yeah I do remember okay so just uh check on our main website which is NW kings.com okay so try to read blogs here because these are written by one of our like few x what we call X students so they in free time they write content for networking as a freelancer because they are doing their job but they want to stay updated with the knowledge right suppose if you guys love technology you love to write you can also contact us and if you want to write some technical blogs but first learn when you learn then only you can write right so this is one of our student uh you can see what are advantages of Hub Hub are more affordable than switches and bridges but they are cost effective provides easy and convenient solution for Network segmentation disadvantages problem so we this is the bridge discussion disadvantages okay so just have a look okay I would recommend you highly to read these type so reading watching practice everything going to be in this batch but I'll provide every content whatever if you love to read I'll give you reading material if you love to watch content we are giving you recordings of live classes extra videos I will also share don't worry okay but just uh be flexible with your learning so the switches are very expensive compared to HUB and bridges okay but the switch is difficult to configure means normal Network normal it guys cannot configure High powerful switches for that you have to learn CCNA ccnp that's why you all are here right so just go to this section blog so you can see we daily write lot of latest content here uh like uh Cloud engineer a guide to become a Cloud engineer AWS Cloud engineer hsrp technical CCNA so you can see CCNA and you can see here uh other uh things also Network Services and all what is it networking now if you see here what is it networking and it networking is uh getting popular day by day because lot of network devices are connecting digitally okay so we have devices like internet firewall printer laptops okay okay so all these things are discuss hsrp will discuss it another topic okay so I'm just showing you that yes you can start learning this content because we make sure the content what we are writing and all is going to be up to the mark okay so just uh go and read this uh section so one said twice a day and try to find uh what we call mistakes this is your homework if because my content writers are also like humans right they might do any mistake if you find any problem and all so uh just inform us okay or just mention in the comment uh in the blog because if you scroll down I think there is a section where you can comment okay and if you can't then uh just let me know I'll figure it out okay so this is all network devices switch we already know this it's a layer to device okay which we will discuss layer but switch is a device where we connect multiple computers with each other okay and what is the work of switch switching what is switching forwarding of frames okay because in switch whenever we send data in switches we call frames when we discuss in the routers we call packets okay so whenever we discuss about routers we always say forwarding of packets whenever we discuss about switches we always say forwarding of frames okay clear we'll discuss more in OSI model but right now just remember this thing so switches are used for connecting more like connecting laptops printers computers okay so they all all these network devices are used okay and this is just a difference just have a look so now what is a gateway so Gateway is just entrance point of a route uh Lan Network okay if you want to connect uh if I show you uh like uh okay so let's say one network diagram any network diagram not any specific but a normal one okay normally basic one where we have one router and all okay so this is a normal I would say this is very very simple Network diagram okay so where we have Internet yeah you guys can see so try to understand how uh these devices are placed I'm not showing you any complex one I'm just showing you basic one so you can see we have internet here right so internet and there is a router which is connecting with me to internet okay so why we have firewall that's for security so that nobody from outside world can attack my company right Fireball is for protection so you can say so Fireball is like protecting me from attackers okay but normally we consider we learn CNS CNP router switches and all okay so you can see here router is here okay then router we have this switches switches connected to router okay and this switches connected to servers then to the phones computers PCS wireless devices then wireless devices are connected to the wireless device okay so in simple language router connect with switches then all computers printers servers they connect with switches okay this is one of the example okay so just try to check Network diagram on Google click on the images and try to check multiple diagrams as a learner this is going to be your homework kind of try to figure it out okay just type here Network diagram okay and try to understand why these are connected like this so that you get some curiosity to learn you can see here now try to understand this this is ISP internet service provider okay this is how you gain The Real World Knowledge also because you are checking the scenarios okay so you can see this is a route rou which is connected to ISP which stand for Internet service provider okay then we have cloud cloud means it could be internet or something like that okay so we have a switch here okay so uh server we can connect with the router also but normally it is recommended to connect with their uh switches so you can see then we have some smartphones computers they all are connected with this switch okay so this is another one of the example and if we go for uh this one again you can see this is more advanced now so where we have router Router is connected to some internet then we have different different locations like server Hotel servers and all okay so we'll discuss these type of connectivity also but as of now uh just understand very basic uh Network okay that we connect router with switches switches with computer I think if you understand this topology this is enough for you right now because you guys are very very new to this field okay okay so it is like you just have to look basic things okay so now you consider now again we have a router here router symbol is circle shaped okay then we have a switch here then we have another switch here okay so now switches are connected with router then all computers are now connected with switches okay server is again connected to router it's uh and we have added a firewall between router and internet so that nobody from outside world can attack me but can you see that we have also added in this scenario maybe a company has a requirement so company maybe it is a sample of any company diagram so you can see we have one more firewall here okay which is protecting my Wi-Fi network so maybe any people guest Network this is like a guest user we will come to your office and connect with Wi-Fi and these will be filter because farall does protect you from outside traffic and it will also protect and do some internal filter also filteration or what we call filtering filtering means okay which user you want to give access to facebook.com so this user a guest you do not want guest to download torrent right you do not want that this guest came to your office and downloading data watching movies okay so obviously you don't want they just get firewall so firewall give some limit okay that he cannot use more than uh 5 mb per second more than not 50 so it totally depends on the speed whatever policies every company has different different policy but firewalls can used internally and firewalls can used outside also so we can place fars anywhere any router can we use a Gateway so what is Gateway so as I discussed Gateway is your router only exit point of land okay so where do you see exit point of land here tell me so all these are landan networks right this is my landan network so exit means exit point of the landan so this switch is also my landan network so this is my exit entry okay so this is where I go to internet right so this router is is working as a Gateway so what is Gateway here so we are as a network engineer this cable which is connected to this switch okay or maybe this cable okay so you can see there is another so maybe there is a small switch here so just understand if this switch is also going to this interface okay so my firewall is also adding so all these users all these users even the guest they all go to internet from this link yeah so the router internal cable okay so the router Lan cable the cable which is going in the Lan Network so as a network engineer we give some IP address here like 1.11.1 we will learn in this course how to configure all these devices like switches routers and all so farall like if you have already taken farall like Paul Alto that's a separate batch not my batch okay that's for network security if you want to add okay but we will configure switches routers layer three switches okay lot of other tools and all so you can see we as a network engineer we will go to this router we will open the command line of this router we will type some some commands here okay and we will configure this router as a Gateway so when we give IP address on router so IP router when we give any IP on the router that router becomes the Gateway of this landan network if I configure IP address like 111 on this cable so the these routers can go to internet with this Gateway are you getting my point so it is like you build your home but you do not have out gate you can't go outside it right I hope you understand so this is all your home so try to understand this is all your home this is all your rooms okay kitchen washroom whatever okay but this is the entry gate so how do you go from outside from your room to outside Market using gate right so router is working as a Gateway for you clear everyone now yes every router has a different Gateway okay so if you have multiple landan networks then router your Lan has multiple gateways also okay so if I show you one example yeah you can see this now okay so yeah yeah this is better okay so now in this picture what we see here do you feel like now yes it's a different kind of batch yeah topology discuss okay so now you see here so this is one of the diagram again what we call topology Network diagram okay so this is one plan Network you can see why I mark this boundary because this Cable cable right you see one cable here so this one cable we have to see this one cable is connecting to some firewall then further these all devices like I put a boundary here all these devices are one Lan Network this is Lan one let's say Lan one after that you can see there is another cable which is this boundary this is what we call Lan two right so now both Lan networks now router will have two IP address maybe this is 1.1.1 and this network has 2.11.1 so now tell me how many gateways router have has right now we have two Lan networks that's why we have two gateways in one single router if you have four different landan networks then it will become four gateways so every landan network has exit path right her L Network all exit paths are called Gateway so router is not a Gateway okay so you can't say router and Gateway same thing router cables or router these cables are called interfaces what we call these interfaces cables where we put l what we call router Port router Port router Port is called interface router Port is called interface and those interface are like gateways okay so when we start doing configuration you will understand understand but as of now just try to understand okay Gateway is like exit point of landan network is Gateway okay so what is modem now so modem is for modulation and demodulation okay so if you heard about uh like uh like everybody knows that whenever we get any connection from uh modem connection uh okay this just hold on so what is modem modem [Music] modem okay so it it is for uh signal transformation basically you picture [Music] okay I think this is better okay so what do you see here okay okay so you can see here let's uh see from the other side that we have Internet okay we have ISP or whatever okay so you can see this is internet or ISP okay so whenever ISP gives signals all signals are in this format this is called analog signal analog analog signal but computer this computer do not understand analog signal so it's like if you see the what we call the telephone cable okay so telephone cable what we call uh like landline phones or something like in previous days okay so the cables they are getting the data as analog signal and this device is called modem which is called modulation modulation and this device is also capable of D modulation D modulation so what is modulation converting analog to digital signals and what is demodulation digital to analog because we want to send data and want to get data back okay so now consider here you have your Facebook server okay so this is your Facebook Instagram whatever okay so this is our computer so so when you open any website or you get any page from Facebook okay so you can see so when you open facebook.com your computer is sending digital signal to modem okay the device you have in your home right now Broadband router the modem Broadband router whatever you say that has a modem capability also okay so you can see we are getting nowadays fiber cables have fiber optical signal okay we'll discuss later on but you can consider ISP gives you connection with the two ways analog signal or maybe it is giving you Optical signal which is with a light fiber cable so modem devices so different different modems some convert analog to digital and some modems convert your Optical signals to Digital Signal also clear or okay because your computer only understand Digital Signal zero and one machine language right so the modems are used to convert your analog signals Optical signals into digital signals so that your computer understand okay that Facebook is sending me this High message and when you forward the data you forward the data you forward in the digital signals okay your device get digital signal this digital signal again transform into analog and go to ISP or wherever it is going clear this is what we call at the back end okay because if you understand that old cables you can see here again like if there is a sender and there is a receiver on internet like if I'm sending data to you okay so one side left side this is my computer okay this is me this is my computer and this is your computer okay so I'm sending my data to modem in a which format digital digital has this symbol this is what we call digital okay and analog is this s signal is called analog if you are a btech student you already know it if you are not then I'm just telling you whenever you see this type of signal in any books this is called digital means computer understand this Digital Signal whenever you see this signal this is called analog signal which means computer directly do not support analog so we have to convert this analog with using modem devices okay the devices what you have in your home so those devices are what we call modem or some people call this router so actually that devices has multiple things router modem everything okay white background okay so k okay so what is repeater see one time only you have to understand this because maybe people will not ask you this in interview but you should know it right what is modem what is the repeater if you don't know then you should not call yourself Network Engineers yeah so what is repeater repeater means like boost the signal if signal is getting weak okay like if you heard about Wi-Fi repeaters if you have Wi-Fi problem at your home you can just put Wi-Fi repeater and the signal will boost right the same goes with repeater amplify the signal basically amplify means boost the signals again very is simple very very simple device okay so this is a repeater suppose you have a very very weak signal so if you place a repeater kind of device it will boost the signal okay and repeater work can be done by switches also if you add a switch in between the cable again it will boost the signal okay so nowadays we do not have separate switches in the market if you just add so what is the problem why why signals are getting uh what we call uh signals are getting weak because there is a limit in landan cables you can't put more than 100 m cable do you know that okay if you don't know normally we place 50 60 70 okay so after 80 90 the signals started getting little bit drop but after 100 m like it is a problem of Lan cables you can't add you can't send more than 100 meter in Lan ethernet cables then we have to buy what we call fiber cables fiber okay if you if you have more than 100 meter distance we have to use which cables fiber for shorter distance like if you have a computer lab one computer lab to another computer lab so then normal what we call ethernet cables ethernet okay ethernet cables or people call them Lan cables okay or copper cables straight cabl so there are lot of names okay so ignore the name just understand whatever commonly used cable you can't send data from one computer to another device maybe a switch or anyone maximum to 200 M but if you want to connect another building from this building and if the distance is around 200 M then what you will do so in this case you add a repeater in between them because when the St signals getting degrade okay the repeater will boost the signal again and it will you can reach 200 also okay the repeater is to amplify the signal or to boost the signals because there is a limit of 100 m you cannot add network devices together with more than 100 met the other solution you have to buy fiber devices because all network devices they do not support fiber right so then you have to buy fiber devices and all so repeater is to boost the signal so repeater is a layer one device repeater is used to reproduce the original strength of the signal or you can simply say boost the signals together so now what is access point guys Wi-Fi devices are called Wi-Fi access points okay so if you go and see there are lot of Wi-Fi access points in the market you can see Aruba is also great company okay Cisco also has good name obviously everybody knows okay TP Link dlink you already know these uh maybe you guys are using them but Cisco is obviously the top one Aruba is also good ubiquity is very good Cisco you Aruba ubiquity okay so the rexus yeah kind of this name yeah okay so all these are Wi-Fi devices company okay Aruba aerohive miraki ruus ubiquity okay so the all these companies make WiFi devices very very popular Cisco Aruba rexus ubiquity aerohive like they are uh new players in the market okay and very affordable devices TP Link dlink are normally used in home networks very small offices but in bigger corporate networks we do not use a DP link day link normally okay if you are using then it's okay but uh big companies or Enterprise they use Cisco and Aruba or rexus also okay so these are Wi-Fi access point what are these Wi-Fi access point so all these are Wi-Fi access point and if you want to place like uh you can place these Wi-Fi devices together and nowadays WiFi access point mesh is also going on so what is mesh like if you have a like a little uh big what we call if you have a small office but you want to connect your office Wi-Fi you get signal everywhere you can buy this bundle and you just Place uh if you are if you have a big home also you can place this wi-fi like this ground first second and all your uh you there will be no dead zone what is dead zone like where you do not get Wi-Fi signal okay this is very very common I'm using it um in my office obviously so because uh and up to 100 plus devices you can connect so for a small company small startup this wi-fi mesh devices are amazing okay and nowadays the latest Wi-Fi is going on which is called Wi-Fi 7 uh which is very costly right now okay one device is at approx $1,000 approx 50,000 India around 900 to $1,000 in us okay there is Wi-Fi 6E also what is this wi-fi 6E Wii 6 WiFi 7 we will learn in this in wifi chapter okay but uh the latest one is right now 6 e devices yeah Wi-Fi 7 and Wifi uh 6E is the mesh setup uh normally people are using this one I think yeah Wi-Fi 6E because nowadays Wi-Fi internet speed you get good internet connection but if your devices you can see here uh in this wi-fi you have around 54 Mbps speed like if you have and always whenever a speed written on the box always divide by two because it's y directional okay whenever you see any device make sure you divide by two because 54 Mbps you will not get 5400 now this device will give you maximum 22 2700 MVPs up to 2GB speed you will get on Wi-Fi around two but if you have more powerful connection 10 GB this Wi-Fi device is not for you if you have 10 GB speed if you need then you have to go for that Wi-Fi 7 which is going but in India I think 1 GB is the maximum we are getting in Broadband in Broadband I'm talking about but I think uh outside India us and all they have 10gb Broadband connections also I think 10gb Broadband USA I think you can see up to 10 GB net Blazer but it is going to be very very costly I think they have a residential and all speed up to 10 GB okay so Google and all they have uh you can see 10 GB internet is coming here is how to get it so this company xinity 10gb so these companies are providing so now understand if you get 10 GB in your home then how you'll get WiFi speed because if you buy normal Wi-Fi devices like Wi-Fi normal Wi-Fi access point those are very very small very cheap very affordable suppose this device it's a good device 2,000 bucks in India appr uh uh $30 20 $30 okay so you can see you are getting 400 MVPs so now just imagine if you get 10 GB connection okay suppose you get this GB okay 1200 MB so if you have one 1 GB which is 1,000 Mbps I'm sure you know right 1 GB is 1,000 MVPs you know this little bit Yeah so now understand if you have 1 gbps 1,000 MVPs connection and if you buy this device and it is written over 867 I told you always divide by two so what is the maximum speed you'll be getting on this device can you tell me guys on Wi-Fi approx maximum to maximum you will be getting this one divide by two so maximum you'll be getting 433 433 MVPs if you use this Wi-Fi device clear everyone so that's why whenever you have a very good internet plan like 1,000 and your Wi-Fi is not giving that speed it is not that ISP fault it is maybe you have do not have that proper Wi-Fi access point for that you have to buy the Wi-Fi latest 6E or something like that okay so they have a model Wi-Fi TP lot of companies have but six e yeah okay so then you can see here uh this is 54 it means 2700 so it will give me around 2.7 gbps so then if you have 1 GB internet plan like Gio and all if you are using an India so then you have to buy these type of Wi-Fi devices you can buy a single pairer also I think uh yeah a okay so you have to buy this type of device so that you get around 1 GB properly on Wii and your laptop should also support 6E because uh whenever you buy any laptop okay suppose if I buy a gaming laptop I love gaming laptops even I'm not using it right now okay but yeah suppose if you buy any gaming laptops and if you check their Wi-Fi always check when you buy these devices because nowadays the Wi-Fi is mentioned over here display graphics operating yeah you can see 80211 ax can you see that it support Wi-Fi 6 okay so now if you want to know you just copy from that laptop section and all so you just check your max speed okay so max speed of WiFi 6 is around 600 to it can go beyond that it can go like 9600 MVPs so it's a good device obviously you should uh you can consider this type of devices because this is a latest technology 6E which is you are getting in the laptop laptops and nowadays uh the mobile phones also have 6E like Apple phones have 6E okay but if you buy a normal uh Android okay I'm not sure but if you just uh try to check any Android smartphone are you happy if I'm sharing this Real World Knowledge stuff take it's not related to maybe as a proper network engineer but yes uh if a manager is saying that my mobile is not getting speed then what will do you can't say Sir buy iPhone right so you should say that technically okay sir your phone do not support that speed because it has a Wi-Fi normal Wi-Fi uh because it's not mentioned here but if you check the proper the Samsung Galaxy M14 something on uh maybe Samsung website and all they have mandatory they have to write everything if you check their catalog and all they we will come to know this device has Wi-Fi five or Wi-Fi 6 this is not my work I'm just giving you idea okay so you can see CPU display camera storage Network you so Sim Sim this is all about 3G 4G yeah connectivity yeah you can see here this device support 802.11 a BG n a maximum is 802.11 AC it means if I go here and check 802.11 AC Max Speed okay so this is going to be maximum maximum it will be 1300 MVPs B directional again B directional because mobile will send data receive data so maximum you will be getting around 650 Mbps on that Galaxy phone if the processor is good other things are also considered right Ram processor all these things are also considered but 600 MB the Galaxy phone will get if you have 1 GB connection at your home you will never get 1 gbps with this Smartphone how cool so never buy a device if you have 1 GB speed so properly utilize that speed if you are paying for 1GB plan then make sure your devices support 1GB PS then only it is good for to go because I think 100 to 100 MB is also good so right now so I'm on my one normal Wi-Fi I have 200 MVPs plan so 200 MVPs is enough I think 100 is also also enough 50 is also enough depends on usage but I need uh good upload speed so some ISP they have different download speed and different upload speed uh so I'm getting good upload speed here so that after the class I upload videos or my team and all so that's why I am on 200 but I think as a normal user 500 plans are also good okay so this is the knowledge about Wi-Fi access points okay so you should buy Wi-Fi access points according to the requirements of company and Wi-Fi access points are also uh we have what we call wlc in companies okay like if you have lot of Wi-Fi devices how you will manage all Wi-Fi devices together Wi-Fi access point if you have 50 Wi-Fi devices in college so so do you go to all Wi-Fi devices and change Wi-Fi passwords do you think that uh is convenient for Network experts Engineers no so when you have lot of Wi-Fi devices lot of Wi-Fi devices and all then you can see there are controllers these are called controllers so you can just buy a controller and configure the controller and all Wi-Fi device you can set password everything will be on the controller so Cisco has a controller which is called Cisco wlc and this 9800 and all these are the latest ones okay so yeah this device looks like a switch switch this device looks like a switch but it is a server for wifi devices understand server of controller basically the correct term is called controller so this different different models are available if you have 500 access point then go for a smaller one if you have 500 access point in your office Big Campus big university okay okay then go for the bigger one it totally again again depends on requirements okay nowadays nowadays you can place this wlc in Amazon also if you want to manage your Wi-Fi but you do not want controller then you can buy virtual controller and add this virtual controller because everything is going in Cloud everybody talks about so CCO everyone is already doing that that my Wi-Fi controller I'm I have 50 offices all all 50 offices Wi-Fi I can configure I can manage from AWS if you know a little bit of AWS you can see I can go I I have to buy license because you can see here bring your own license b y l bring your own license okay like B yod bring your own device somewhere bring your own license so you can place wireless controller in a cloud that's super knowledgeable things that's why I'm saying this is initial batch okay so try to cover basics because everywhere Basics are going to help you a lot in your career okay if you're good at Basics then you will be become expert right obviously okay so these are the commands like Ping uh I'm not using Windows laptop but try to check these commands I'll show you in Practical ping so ping is basically for like uh if if I want to test if I'm connected to google.com I can say ping google.com Okay so what is this this is what we call a tool to check the connect whether the other device whether Google is connected to me or not so right now you can see I get ping replies this is called ping replies we'll discuss about what is this TTL time what you have any question so we'll discuss later on and if you want to see your uh IP address then there is a command called IP config but this is a Mac so I have to write here if config for Linux Mac for Ubuntu all these operating if config Windows user will type ip config okay if config so you can see it is giving me okay I'm connected to this is little yeah yeah so you can see I have this IP address on my interface Wireless uh inet inet is like internet address you can say or IP address 1921 16113 this is my IP address you can run ip config in your laptop and if you want to see the MAC address then ip config /all okay this is for Windows but for Linux no need to check if config all you can see IP address here and this is what we call Mac address on top okay if you are using Linux or Mac okay the best you can go to the settings okay you go to the network you can go uh I'll show you in Windows also but this is how we can check here also okay this is uh the GUI I click on the details okay and you can see 192 160 1.13 because a lot of companies are using Mac as a mostly software developers get Mac operating system okay so maybe if you get a job in any company maybe lot of people are using Mac okay so you should know about all the operating system a little bit okay so 1.13 you can see I have 1.13 IP and uh if I want to see my Mac address I go to the hardware and you can see this is my Mac address okay so now if I copy this let me show you one amazing thing if I copy this if I can copy yeah if I copy this sometimes what happens in your company uh you will be getting complaints that this Mac address is from this Mac address we are getting lot of packets we are getting lot of broadcast packets okay so whenever the day come when you check log and see this Mac address is getting lot of we are getting lot of broadcast from here maybe somebody is doing a tax maybe employe is doing some testing okay so then we go to this website Mac vendor lookup.com and you can always copy paste that Mac address whatever you have and check this device is from Apple yeah okay so window uh Mac address will not show you Windows here Microsoft it will show you some companies like real Tech real Tech Su some companies which are making Nic cards for or motherboard comp motherboard who makes motherboard so motherboard company's name you will see here and then you will identify okay this is a Windows uh some gu is using a Windows or computer or maybe Android or something like that okay so this is how you check men Mac vendor lookup okay to check your internet speed as I mentioned I check fast.com which is by Netflix basically this is made by Netflix I think this is better than speed test I feel like I'm using it and it gives a fast result than uh speed test the other website I would recommend you to check here uh submarine cable do Mac last time also I mentioned but again I'm repeating this uh you can see submarine cable like under C we have all fiber cables so cable explore okay just try to check all the cables one by one okay not all cables just try to check one or two cables and read about them how they made it how they place it okay so this is a company like I V cable this is a company who put fiber cables under C their website is not working I think they have spent all their money in the submarine cable uh so okay so this is all submarine cable and then another website what is my IP there are two website what is my IP what is my IP address.com you go here and check okay this is my IP this is my location and all okay so IP address look up and you can also paste the public IP of any other vendor suppose you have any public IP okay and just you can see IP address look up okay and copy paste that IP address if you get any lookup so you can see this IP belongs to some kikan University or something office Bank 202 something randomly I just entered okay so this is uh just a website to check your public IP okay what is my IP address.com okay so this is what we call public IP IP look up like if you want to see IP from other side okay so you can just paste that public IP and just get IP details and just try to check okay what's the location okay so this IP address belong to Ireland Dublin and this is not exact location because this will give you not user location it will give you ISP location okay so how people track some suppose you just email Modi G okay that we are doing some illegal things or something just randomly people for just uh by what we call it's not fun basically it's just what we call is the correct word right so if anybody try to do anything illegal and if they just send a email to maybe government of India any email okay we have this this so much or something then how they track suppose one student from our batch parag okay or tanu okay if they send any wrong email to uh government of India website or something on their website okay easily available on internet right and if they just randomly write any bad things okay we are doing some this this activity or whatever which is uh problem for our uh Society okay then how they track it they basically track your public IP okay and if you're using any proxy because lot of softwares are there lot of VPN are there okay so like there are a lot of softwares like uh carbon VPN hotspot VPN lot of VPN and you can change your locations like it will give you option okay you want to use which which country VPN okay but somehow this company if I change the IP okay okay I'm not uh click connect but if I change it maybe my zoom meeting will close I'm not doing that okay so but yes if you change the location and if any government of India or any country government they will track they will connect with VPN connect servers they will tell you these companies will tell the organizations okay this is the real public IP of that user okay so never try to do that if anybody is listening okay because it's easy for them to track okay so right now you can see I'm just showing you I'm showing you trace email okay let's try to trace email I wish I could take cyber security batches but I'm not that free Okay so let's say this uh okay let's say this is LinkedIn actually you already know this is a LinkedIn email okay let's go to spam and uh do not check if I'm getting spam with any okay so this credit card okay stancy credit card Auto Marketo something okay I can't see the email also because Google already identify but if I go here and if I click here show original can you see that if I click on show original okay and uh if I go to trace email and it is saying just you have to copy paste from Return path okay where it is return path given so I go to this original message I find return path I have to copy paste from here until where till you get this this content transfer okay content transfer to copy we'll copy till content transfer something I think content transfer till here copy and let's paste this paste this in this for section and find email sender okay let's see so this is the public IP of that guy this is the public IP but actually he is not using any particular server because he sent me email from they using Gmail and easily you can contact gmail and say that okay this Auto Marketo has a Gmail subscription please check because uh you can see here now mc. autom market.com this is their server from they are sending emails and they are using some Gmail servers because IP yeah only yeah mail Auto they are using mxg google.com so this MX means mail servers Google M server use okay so basically this public IP is Google IP they are using Google okay you can check further also like uh if you go to here sh trust spam it okay finally back links and rankings okay let's try this one show original again we go to the return path and we try to copy till content transfer something copy okay so I just this is just again that extra stuff you should know a little bit because somehow down the line you will go in network security yeah you can see now this public IP and this public IP is also using because nowadays everyone is using Gmail uh what we call G Suite you know right now what's called Google g s is changed to Google workplace something yeah you see any company can create their email ID on Google right that's why everyone is using Gmail because at gmail is more common so mostly all companies are using Gmail and you can see to uh have your company email on Gmail they are charging around uh 136 rupees approx $2 $3 per user okay so you should understand uh a little bit of of these type of stuff also okay so get Mac this is the command to get all your Mac addresses Next Step this command is very good if you want to see what network connections are running in your laptop so sometimes you feel like your laptop in Windows I have seen sometimes your cursors are moving here and there without you are touching and sometimes there some wirus attacks or something happening so and you feel like oh my I got hacked or something so you can always check this net stat and try to see what is net stat means your computer IP and this your IP address has connection with different foreign addresses so right now you can see here uh I have this address 595 BG nnx something and if I try to check what is this ping okay this is uh not but yes you can see your public IPS you can see this is your Source IP and this is the public IP of the server and connection is established right so means my computer has a connection with the server 170 and this 170 you can copy you can go to your this website what we call what is my IP you can try okay my computer has a connection with which vendor IP and try to copy paste that IP get I details and you can see right now I'm taking class on Zoom that's why my computer is showing me that I have connection with the zoom yes agree okay so all these things you can check in your task manager also I think in Mac this is what we call activity monitor in this also you can go to your network and you can see all your connections you can see data yeah and all services what are using what how much bandwidth so I'm on zoom and I have already uploaded 4GB data today for this class okay so Google Google Drive 7 MV so this is the today data only I think I think yeah recent data okay from here you can pick okay uh this application is taking my lot of bandwidth and you can kill the process okay but don't close the zoom when you are taking class yeah okay so this is the work uh I think that's enough and after that so tomorrow we'll see what is the difference between Mac and IP address we will discuss about uh uh if if you are able to understand I can teach this Frame right now or maybe we can discuss in between because this is going to be what we call header so what we can see uh what we can do we can uh skip this part in tomorrow I think let's start with the OSI model and then after OSI model we will do subing okay so tomorrow we will cover OSI model clear everyone and very very important OSI model important I would highly recommend you if you have time check OSI models on YouTube okay but on our Channel okay lot of Osa model and try to all for next 10 days I'm giving you this suggestion if you really want to be expert in Basics so 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 [Music] 22 so I have 23 OSI model videos on my our channel so just try to check if you only watch one video a day for next 10 days your Osa model will be amazing I'll teach you live also obviously but obviously my all classes are different what I'll be teaching you tomorrow it is not like [Music] in okay so whatever Osa model I covered 10 months back maybe tomorrow it will be a little different because it's a very very lengthy topic so you can see lot of students in this previous batch also so where we discussed about OSI model in detail and this 2 hours 35 minutes video I would highly recommend okay not just today I would say this week Wednesday Thursday Friday Saturday Sunday you have five days try to watch one video a day and your Basics will be awesome trust me okay so again I'm sharing this link with all of you and no all videos are English you three four videos are Hindi you can see o model Hindi this is English when we have any Hindi video we mention it as a Hindi video and when we don't mention any language it's English clear listen just for 10 seconds you will come to know English or Hindi okay so you can see and try to watch Hindi also okay so it's okay and animation content is there this is I think if you ask me the best Osa model which batch I have taken the best Osa model class so that's this one maybe the more lengthy the more in depth I went like you can see 200 two hours video and uh uh the very very old don't watch 9 years back videos guys please I was like very young okay so Osa model it's uh try to watch 2000 just check okay it's try to watch okay you will come to know easily that which videos are best 19 is also good uh because all has similar Concepts uh but uh you will automatically this 2020 I have explained in such a different way you can see where I using a notepad and where I'm actually say showing you the flow you can see how the data is going I'm showing you every step here in this video in Hindi version and the similar content you get in English also uh somewhere in this video maybe day three something okay so and this video is also good where I put the handwritten content everything one by one okay so 20 hours of OSI model is already I think if you watch English or Hindi easily you can get 15 20 hours of content okay so and other uh if I I do not want to say anything but trust me I've I've seen lot of Osa models on internet just for checking and uh people these guys they are not from the network Industries okay so they may be good at teaching just basic uh sorry if anybody okay you can see sender application this is just to prepare you for some government exams and all okay so this will be mostly everyone here are not from the industry that's the only difference okay like this guy he's into some normally making cyber security video he can't explain IDE model the people who actually work in Industry are you getting my point the only difference what makes people better than others is uh following the right people yeah because everyone is learning everyone is watching YouTube everyone is learning but if randomly watching anyone then you are wasting a time bro yeah time is more important if you spent 50 hours learning from these guys and after that you still not clear about OSI model Basics then you wasted 50 hours of learning okay so I'm just because I've seen this thing people they attend my batches and they go to YouTube and randomly watching videos okay so it is like you're contradictory you paying for Life batch and then you watching YouTube videos randomly so I have one word so learning is okay learning is easy but unlearning unlearning means whatever you learned wrong things this is more problem unlearning is more difficult than learning yes or no if you learn wrong content mean it is very difficult to remove it from your brain that's please understand I think uh nobody has told you this any time but this is very very important okay so learning from right uh person it's very important just what I recommend you always follow YouTube it's good try to check the profile of that guy who is teaching okay okay so who is teaching who where he has worked all those things and then try to because when you watch one hour video on YouTube uh it's not about it's free but your time is not free okay so I think uh the next thing see you all tomorrow and I would
