Thread: CVS in programming

I want some help regarding the CVS in programming language. I found it in many books but I didn’t find real meaning of it. So please provide some details about the functionality of this CVS concept. Any help will be appreciated.

Concurrent Versions System (CVS) is version control Client-server to many people to work concurrently on similar set of files. Big development projects are generally depending on this kind of system to permit many developers to work on similar project. CVS permits, as its name suggests, handle concurrency that is able of detecting version clashes when two people work at once on same file.

Using CVS client, every user wanting to work on project regains working copy with operation known as checkout. When user completed editing file, it send modifications to database. This is known as commit. As developers can work concurrently on copy repository and submit their modifications.
