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 a DVCS that stores data in a file system made up of snapshots. Each time you save a changed version of your project — called commit — Git creates a snapshot of the file and stores a reference to it. If the file has not changed, Git only stores a reference to the already-stored identical version of it. Git mostly relies on local operations because most necessary information can be found in local resources. This allows for process expediency because a project’s history resides on the local disk, eliminating the need to fetch history information from the server, and allowing one to continue work on a project even when not online or on a VPN.
Version Control is a system that allows you to revisit various versions of a file or set of files by recording changes. Through version control, one can revert a file or project to a previous version, track modifications and modifying individuals, and compare changes. By utilizing a Version Control System (VCS), mistakes with files can easily be rectified.
