CVS Concurrent Versions System (CVS) is an older, open-source version control system that allows multiple developers to collaborate on a project by tracking changes to files and managing different versions. It enables team members to work simultaneously, merge updates, and maintain a history of revisions. However, it has largely been replaced by more modern version control systems like Git and Subversion (SVN).
