Definition
Version control systems (VCS) are tools that help manage changes to source code over time, allowing multiple developers to collaborate on a project.
Types
There are two main types of VCS: centralized version control systems (CVCS) and distributed version control systems (DVCS). Examples include Subversion (SVN) for CVCS and Git for DVCS.
Benefits
Benefits of using VCS include tracking changes, reverting to previous versions, collaboration among team members, and maintaining a history of code changes.
