Git is the most widely used free open source version control system platform for software developers, it is used to track changes in source code files i.e. view historical data and to coordinate collaboration among programmers working on the same projects. Git is easy to use and is also very fast hence it is loved by most software developers worldwide. It offers features such as multiple workflows, cheap local branching and convenient staging areas making it better than Software Configuration Management (SCM) tools.

Git was originally developed by Linus Torvalds who also developed the “Linux” open source operating system, Git was developed further by Junio Hamano who currently maintains it with other developers. It was first released on April 7, 2005 and is updated frequently. Git is written in Python, C, Perl, Shell and Tcl programming languages. The Git directory is a complete repository containing full history and tracking of projects.

Git means “stupid person” in British slang, Torvalds named it so because he described git as “the stupid content tracker”, it is also called “global information tracker”.

Git is known for its distributed architecture, super speed, security, flexibility, top performance with rapid branching, fetching and merging. Git was developed on Linux OS but offers support for Windows, Mac OS, Solaris and others.

Git’s repository files combine delta encoding, compression and explicit storage of directory and version metadata content. Git files are secured with SHA1 which is a secure cryptographic hashing algorithm, it protects both code and historical data from attacks.

Git is a flexible platform as it supports different non-linear development workflows, works well for small and big projects and is compatible with most protocols and systems.
