Computer Science

I might be taking a course in Computer Science at a Uni soon, what languages are commonly used @ Computer Science?

Of course, I think they should use functional languages.
Not to sound like a jackass, but why?

Oh and if the answer to that question is an explanation of the whole paradigm, I'm sorry. I just started learning Haskell a couple of days ago, so other then strict typing, everything being an expression, and how imperative languages can be sometimes better if memory is an issue, idk.

zomg, did I answer my own question?
