What is Git? Explained in 2 Minutes!

[Music] so what is git and why is it so popular git is the most popular version control system in the world a version control system records the changes made to our code over time in a special database called repository we can look at our project history and see who has made what changes when and why and if we screw something up we can easily revert our project back to an earlier state without a version control system we'll have to constantly store copies of the entire project in various folders this is very slow and doesn't scale at all especially if multiple people have to work on the same project you would have to constantly toss around the latest code via email or some other mechanisms and then manually merge the changes so in a nutshell with a version control system we can track our project history and work together now version control systems fall into two categories centralized and distributed in a centralized system all team members connect to a central server to get the latest copy of the code and to share their changes with others subversion and microsoft team foundation server are examples of centralized version control systems the problem with the centralized architecture is the single point of failure if the server goes offline we cannot collaborate or save snapshots of our project so we have to wait until the server comes back online in distributed systems we don't have these problems every team member has a copy of the project with its history on their machine so we can save snapshots of our project locally on our machine if the central server is offline we can synchronize our work directly with others git and mercurial are examples of distributed version control systems out of all these git is the most popular version control system in the world because it's free open source super fast and scalable operations like branching and merging are slow and painful in other version control systems like subversion or tfs but they're very fast and git we'll talk about this later so git is almost everywhere more than 90 of software projects in the world use get that's why almost every job description for a software developer mentions git so if you're looking for a job as a software developer git is one of the skills you must have on your resume you should know it inside out you should know how it works and how to use it to track your project history and collaborate with others effectively if you want to learn git i have a one hour tutorial here on my channel the link is below this video if you enjoyed this video please give it a like and subscribe to my channel for more videos like this [Music] you
