Git is an open-source version control system that was developed in 2005 by Linus Torvalds and other Linux kernel developers. It is a tool that helps a software development team to manage changes and keep track of every modification in the code over time. Developers can always compare the latest code changes with earlier versions of the code to fix if any mistake is made in the code.
Git is used for handling projects of all sizes, from small to very large.
Git was designed for use in a distributed environment which means that the repository is not centralized, every team member has a full backup of the repository where they can create branches, commit changes, and perform other operations all offline. They need network connection only to publish latest changes to the main repository or retrieve latest changes from the main repository.
Git allows multiple programmers to work on the same project together. A team member can create a separate branch to work on files and easily merge those changes of the file to any other branches.
