Git is the most popular version management system mostly used by Software Developers for  Source Code Management.

It was created by Linus Torvalds. Yes, the same person who created the “Linux Kernel”.

One of its prime feature is, it keeps track of changes made to files and directories. Specifically the text changes made in the plain text files.

So if we have 3 versions of files, then Git allows us to move back and forth between these versions, also allows to compare these versions and see the difference between these versions.

It is also referred as Version control system(VCS), or Source Code Management system(SCM).
