Git is a version control system that allows programmers to track and manage changes in the source code while developing software. Git was designed to handle both small and large projects with equal efficiency. It allows multiple users to work on the same project independently, while offering tools for easy merging of changes. It enables the creation of separate branches in the project, which allows for experimentation and development of new features without affecting the main production line of code. Git is also highly efficient at managing change history, allowing users to easily revert to previous versions and identify when and by whom a specific change was made. Git was originally created by Linus Torvalds in 2005 for the development of the Linux kernel.
