Computer Science Lockdown Quiz

okay g'day all and welcome to another video so today we've got something fun this is just a bit of fun for our lockdown yeah everybody sort of stuck in their houses at the moment due to this horrible virus going around but I was watching Jimmy Carr and he had a marvelous idea it was a lockdown quiz just to keep us all entertained and I thought wouldn't it be fun to do the same thing for computer science and here we are so this is the computer science lockdown quiz alright so the quiz is going to be broken into three rounds each round is going to have ten questions the first two questions are going to be number based number formats and that sort of thing then we're going to have general knowledge questions then we're going to have two questions on people important people in the field of computer science we're going to have two questions on acronyms initialisms and terms and then the final two questions of each round are going to be pictorial questions all of the questions are multiple-choice and there's going to be three choices for each question you can have a guess if you don't know the answer so at the end of the rounds we'll go through the answers I want you to keep a tally of what you got and leave a comment down below if you want to share I would score terribly yeah I'll get about two I think which is unlikely even by chance okay so I just want to say if you enjoy these videos then now please consider becoming a patreon over on patreon so I'll leave a link up above and another one down below in the video description as it really does help me to make more videos okay it is Noora round number one number four Matt's question one when represented in binary how many ones appear in the number fifteen is it seven four or one question number two which is larger of the following three terms for data is that zettabyte is that yottabytes or is it petabyte the zettabyte a yottabyte or petabyte which one's bigger all right moving on to the general knowledge round one question number three who was ADA Lovelace's father was that a William Shakespeare was it be Lord Byron or was it C Bill Gates who was ADA Lovelace's father was that Shakespeare Byron or gates alright question number four control and what other key is commonly assigned to the shortcut for paste is it X is that the V key or is it s question number four all right round one people question number five who is the author of the seminal work the art of computer programming was it Grace Hopper was it William Shockley or was it Donald Knuth alright question number six in 1975 Paul Allen and who else licensed their basic programming language two myths for use on their Altair 8800 computer was it John Titus was it Bill Gates or was that Steve Wozniak John Titus Bill Gates or Steve Wozniak wall right moving along now we are around one acronyms initialisms and terms all right question number seven one of the first computers the Aniak is an acronym for electrical numerical integrator and what starts with a C is it computer is that calculator or is it contraption ENIAC notice it's 10 where are question number 8 the acronym dose stands for what operating system is it denial-of-service disk or dank well who knows what a hard question ok moving on to the pictorial questions from round 1 question number 9 take a look at your monitors as though you're not already this is a famous 3d test model this teapot is named after where it was originally used it is called the watt teapot is this the Utah teapot is this the Arkansas teapot or is this the seattle teapot what do you think very very famous 3d model there ok question number 10 the final question of the round another pictorial won't have a look at your monitors now what is this is this a Commodore 64 is this an Atari 2600 or is this actually a Pentium 2 beautiful wood finish a Commodore c64 an Atari 2600 or a Pentium 2 what do you think that is alright and that my friends is the end of round one let's have a bit of a look at the answers okay so the the answer to the first question the number 15 has four ones in binary it is one one one one would you believe it question number two which of the following terms is the largest it is the yottabytes which means that two to the power of 850 billion or something that's a it's a huge amount of storage but yeah the yottabyte is the largest at a zettabyte yottabyte and petabyte okay question number three who was ADA Lovelace's father well that was Lord Byron good stuff famous family Wow question number four what's the shortcut for paste it is ctrl + V question number five people who wrote the art of computer programming well that was Don Knuth now Donald Knuth absolutely amazing set of books okay and question number 6 Paul alland and who else licensed their basic programming language to mitts for their Altair 8800 computer that was Bill Gates but before he started selling us all windows he was busy licensing his basic programs good stuff mr. gates ok question number seven Aniak is an acronym for electrical numerical integrator and calculator that's a tricky one not a lot of people not a lot of people nowadays talk about Aniak but i think i think it's fine time that we do all right and question number eight DOS stands for disk operating system yeah there you go certainly in security DOS stands for denial of service but the operating system it's disk operating system ok question number nine our pictorial question this is a picture of the Utah teapot yeah the Utah teapot good stuff still in common use today you can find this in modern 3d programs as well okay question number 10 what is this beautiful wood finished console this my friends is an Atari 2600 got to love it ok well I hope you all got 10 out of 10 let's move on to the next round shall we okay round number two question number one number formats what is the decimal equivalent to the hexadecimal number a 1 is it 161 is that 512 or is it 100 the decimal equivalent for a 1 okay question number 2 as signed 8-bit integers signed which of the following values is the maximum is it 0 1 1 0 1 1 1 0 1 0 0 1 0 0 1 0 or 1 1 1 1 1 1 1 1 signed 8-bit integers which is the largest those were fairly tricky let's move on to general knowledge now folks question number 3 round 2 in 1996 a computer beat mr. Gary Kasparov the then-current world champion what was the name of the computer was it a deep blue was it be big blue or was it see dark blue no actually the first time that a computer ever beat the reigning world champion in chess and we've pretty much failed two computers playing chess ever since then so thank you Gary for giving up that little trophy Gaza legend question number 4 for which encryption device did Alan Turing discover a vulnerability was that the Hailie machine was that the Enigma machine or was it the crypto nomicon Haylee machine enigma machine or crypto nomicon now I hope everybody knows that there was a movie about Alan Turing made recently maybe that'll help if you just pop out the DVD and whack that in your blu-ray drive for question number 5 moving on to the people section of round 2 who due to his contributions in telecommunications and cryptography is often called the father of information theory was it Claude Shannon is that an Thompson or is it Eric Idle father of information theory who is that who Claude Shannon ken Thompson or Eric Idle question number six what is the first name of the namesake of the famous fractal the Mandelbrot set what's his first name spoiler alert last name is Mandelbrot but what is his first name yeah who come up with the Mandelbrot set was it yarn Mandelbrot was a Benoit Mandelbrot or was it Gustav Mandelbrot yarn van wah or Gustav okay moving on to acronyms initialisms and terms the initialism IBM stands for international what machines is it business basic or blue IBM what does it stand for okay question number eight HTTP stands for what Transfer Protocol is that hidden type Transfer Protocol Harry Truman Transfer Protocol or is it hypertext Transfer Protocol is it hidden type Harry Truman or hypertext HTTP what does that stand for okay moving on to question number nine this is a pictorial question I want you to have a look at your screens and tell me what part of a computer is this it'll seem easy if you know what it is but if you've never seen one of these things it's gonna be quite difficult yeah so how many of you are out there build your own computers now is this a graphics card is this a power supply unit or is this Ram sticks what part of a computer is this and question number 10 this is another pictorial question have a look at your screen this image has become historically significant in computer science as a test image now for more than four decades what is the name of the image and the first name of the model is that denise is that Lenna or is it Abigail and that my friends is the end of round two okay I hope that wasn't too hard let's have a bit of a look at the answers so that we can tell you what we got okay question number one the answer there a one is hexadecimal for 161 okay as signed 8-bit integers which of the following is the maximum it's actually 0 1 1 0 1 1 1 0 it's a the first option yeah so the other two options actually have the same bits set over the left okay question number 3 what was the name of the computer that beat Gaza Kasparov the chess champion well the name of the computer was deep blue there you go deep blue now from IBM amazing story really he he actually accused it of cheating yeah initially I don't think he holds to that but on some strange moves in those games question number 4 Alan Turing discovered a vulnerability in what machine that was the Enigma machine would you believe it yeah the Enigma machine good on you Alan Turing actually one of the most amazing amazingly intelligent people ever just an amazing amazing man okay who was the father of information theory people that is none other than mr. Claude Shannon of course I hope you've heard his name absolute champion and monster in the field of computer science mr. Claude Shannon is the father of information theory question number 6 the Mandelbrot set was invented or discovered by none other than Benoit Mandelbrot yeah Benoit is his is his first name their amazing fractal just beautiful stuff ok moving on to the acronyms and initialisms IBM stands for international what Machines its International Business Machines yeah we need an a there Business Machines HTTP stands for what Transfer Protocol that is hypertext Transfer Protocol question number 8 hypertext ok question number 9 the pictorial questions those little things just there are of course Ram sticks that's your system memory right there yeah that's Ram sticks or Ram dims yeah and question number ten who is this beautiful model Josiah used in test images all over the world for the past 40 years that is Lenna yeah Lenna the image is called Lenna and that my friends is the end of round two so tally up your answers I hope you are currently sitting at about 20 correct but um let's move on to the final round round number three okay round number three question one this is number formats how many bits is used in the exponents of an I Triple E 754 single precision floating point number is it - is it four or is it eight how many old what's the Creole videos do you watch question number two what is the maximum value that an unsigned short integer can store in decimal unsigned short integer is at 256 is that one million or is at 65535 unsigned short integer maximum value all right moving on to general knowledge question number three which device was found in 1901 in a shipwreck is dated to 100 BC and is believed to be an ancient Greek analog computing device is that a the Hellenistic tally stick B the Babylonian abacus or C the Antikythera mechanism Hellenistic tally stick Babylonian abacus or Antikythera mechanism question number four the Apollo guidance computer AGC used on Apollo 11 mission that successfully landed on the moon had the equivalent of how much RAM was that four kilobytes 16 kilobytes or 64 kilobytes how much RAM does it take to send us to the moon absolutely question number five who along with Steve Jobs co-founded Apple was it Tina Turner Bill Gates or Steve Wozniak who along with Steve Jobs co-founded Apple was a Tina Turner Bill Gates or Steve Wozniak question number six who invented the famous game of life automatons simulation game was it John Conway Steve Jobs or Barry Manilow John Conway Steve Jobs or Barry Manilow the game of life who made that okay moving on to acronyms and initialisms what is the abbreviation for the part of a cpu which commonly performs logic and arithmetic is that the ALU is that the l1 cache or is it the ATU ALU l1 cache or a GU question number eight what is the common term for the circumstance where two or more threads might attempt to update the same value simultaneously commonly leading to logical inconsistencies is it read-modify-write is that called a seg fault or is that called a race condition it either leads to trouble or lots of fun I don't know but either way it's called read modify writes or is it called a seg fault or is it called a race condition I don't know I don't know the answer what could it be question number nine a pictorial question here I want you to have a look at your screen and I want you to tell me what is the capacity of this is it one point four four kilobytes isn't one point four four megabytes or is it one point four four gigabytes what could it be the capacity of this okay question number 10 the final question this is a little bit special this one this is going to be a sound so turn up your speakers or put on your headphones or whatever I want you to listen to this sound [Music] [Applause] [Applause] okay and the question is in the 1990s this sound was very common when would you most likely hear it would you hear it when your printer is aligning heads would you hear it when your hard drive is performing a defrag or would you hear that when dial-up is connecting to the internet printer aligning heads hard drive performing a defrag or dial-up connecting to the internet and that's all the questions folks so let's go back to the top and we'll start the answers for round three good luck I hope you got everything right let's see okay question number one and I Triple E 754 floats has eight bits in its exponent eight bits there 32 bits wide and eight bits is what we needed there okay question number two the maximum value that a short unsigned int is you can store is 65535 question number three general knowledge the device that was found in a shipwreck and is believed to be an ancient computing device is called the Antikythera mechanism absolutely astonishing cold work in that thing it's a marvelous thing named after the islands where it was found off the coast of how much ran did the Apollo guidance computer have that was four kilobytes four kilobytes of RAM got them to the moon if you use your memory well people all right question number five people who along with Steve Jobs co-founder Apple that was C Steve Wozniak yeah Steve Wozniak question number six who was the inventor of the very famous game of life automaton simulation game that was none other than mr. John Conway another absolute legend in the field of mathematics and computer science okay question number seven the parts of the computer that performs logic and arithmetic that is the ALU yeah the arithmetic logic unit good stuff hope you've got that one right the circumstance where two or more threads attempt to update the same value at the same time that's actually called a race condition yeah in parallel programming a race condition and on to the pictorial questions that my friends is a two-disc a floppy disk yeah and its capacity is 1.4 four megabytes yeah almost nothing really the other days of yore okay and the final question that sound that we heard when are we most likely to hear it you're most likely to hear it when you're connecting to the Internet that's the sound of a dial-up modem connecting to the Internet and that my friends is the end of the quiz okay so I hope that we all got a few answers there correct just leave a comment down below - so how many you got correct so that we can all compare hmm yes for watching have a good one oh yes [Music]
