GIT stands for "Global Information Tracker". Git is a DevOps tool used for source code management. It is a free and open-source version control system used to handle small to very large projects efficiently. Git is used to tracking changes in the source code, enabling multiple developers to work together on non-linear development.
For programmers, Git is like a set of pencil and eraser. We write code and if we don't need that line/block of code or there is some error in the code we do erase it and rewrite it. We can also find who wrote it and what changes he/she make to that code. And we can also find when something was done to code. At a time, so many persons can work on the same program/code/project.
Git is a powerful tool, but it has a reputation of baffling newcomers. It doesn’t help that most people are simply thrown in at the deep end and expected to swim. With the right knowledge, anyone can master git. Once you start to understand it, the terminology will make more sense and you’ll (eventually) learn to love it. Stay strong
