What college cles should I take for?

I love computers and I'm very knowledgeable in computers but there are tons I still don't know. I want to go to college so I can learn pretty much everything there is about computers, from fixing and repairing them to programing and web design. Basically I want to be as smart in computer as McGee On NCIS if you know who I'm talking about. So should I study computer science? Or is there more cles?
