Version Control System or VCS are tools with the help of which you can control and keep a track of code changes if any. It acts like a database where you can store all the snapshots of the project that you take. A VCS allows you to save as many snapshots of the entire project as you may require, irrespective of the time you save it. Not only will it follow every little alteration in the project files, but also record the details about the person who makes the change, the cause of such an action. The VCS further refers to the issues that got fixed or the increased complexities that commenced post the change. VCS also enables you to check out and differentiate between snapshots of older codes and present ones.
