Can you explain what is meant by version control system in software development?

A Version Control System (VCS) is a tool that helps developers track and manage changes in source code and other project files. It keeps a history of changes, allows multiple people to work on the same project simultaneously, and also facilitates reverting to previous versions when necessary.

Popular version control systems include Git, SVN, Mercurial. For example, Git allows creating branches for developing new features and then merging them with the main branch, which simplifies teamwork and code quality control.
