Question

What do you understand by a Version Control System (VCS)? Define its uses.

Answer 1

A Version Control System or VCS is a system that is capable of recording changes made to a file or a group of files over time. Git and Mercurial are two of the most popular version control systems. Important uses of a VCS are:

1. Check what was the last modification that caused a problem
2. Compare the changes made over time
3. Identifying who introduced a new issue and at what time
4. Revert a file or files to some earlier state
5. Revert the complete project to a previous state
