What computer programs are you familiar with?

Assuming you were asked the question originally, and are looking for an answer, there is nobody more qualified than yourself to answer that question; it is a question about your personal ability.

I am personally familiar with hundreds, if not thousands, of software applications, commands, operating systems, and so on, ranging from the mundane to the esoteric. My knowledge generally encompasses Microsoft-based and Linux-based Operating Systems, and many of the common multimedia, administration, servers, programming, file sharing, and office suite applications they have to offer. In fact, it would take me several hours just to compose a comprehensive list of software I am familiar with.
