As James already wrote, it's an interface to a 3rd party version control
system. 

Microsoft VSS comes with some Microsoft development tools, and as such is a
commercial solution.

CVS is a free open source version control system (for example Sourceforge
uses it). It comes in basically two flavors: the "traditional" CVS and
CVSNT. CVS runs only on *x type systems, CVSNT has ports for Windows and
*x. Start with http://cvsnt.org/wiki.

No. Basically, you keep various revisions of your files in a repository. In
your working copy of the repository files (often referred to as your
"sandbox") you have only one of these revisions; often (but not always) the
most recent one. Whenever you want to create a new revision in the
repository, you "check in" your working file.

Doesn't matter. You can use version control with all kinds of files. (Some
tools that auto-generate a lot of files can be difficult to deal with in
terms of version control systems.)
