In these and other applications what does the "RC" stand for?

There's a bit of interesting historical perspective about its derivation on this page:

"rc" derives from "runcom", from the MIT CTSS system, ca. 1965.

and that

"rc" in Unix is a fossil from that usage.'

It stands for Run Commands

And as the name already says it can contain a listing of commands to run. For example in a xinitrc file You can list commands to run when initializing X. so you can make a Xterm window popup, or load GDM/Gnome.

    Although, this isn't always the case, for example, Gimp stores it's configuration files in files named colorrc, contextrc, controllerrc, etc. – MiffTheFox May 23 '10 at 13:46
