Version control is a system that helps manage changes to files, particularly in software development. It allows multiple people to work on the same project without overwriting each other's contributions. By keeping a history of changes, users can track modifications, revert to previous versions, and understand the evolution of a project. There are various version control systems, such as Git and Subversion, that provide tools for collaboration and organization. These systems enable users to create branches for new features, merge changes, and resolve conflicts, ensuring a smooth workflow and maintaining the integrity of the project.
