A Version Control System (VCS) is a software tool used to manage changes to source code, documents, and other files. It allows multiple users to work on the same set of files simultaneously and tracks changes made to those files over time. VCS keeps track of all changes made to files, who made those changes, when the changes were made, and why they were made.

Version control systems are particularly important in software development because they enable developers to collaborate effectively and track changes to code over time. With a VCS, developers can work on different parts of the same codebase simultaneously without overwriting each other’s work. This allows for better collaboration, faster development, and fewer errors.

Some of the most popular VCS tools include Git, SVN, Mercurial, and Perforce. Git is the most widely used VCS and is used by most of the modern software development teams due to its distributed nature, fast performance, and extensive community support.
