The go to guy for all of your computer repair needs. You all know him in a way. Sitting in your class with a laptop running some weird OS you don't recognize, always speaking more in technical terminology and numbers than plain English. Often quiet and somewhat introverted, the computer guy is always willing to lend a helping hand to someone in dire technological straits. Often more friendly and less odorous than other varieties of his kind such as the computer nerd or Linux fanatic.
Distraught student: Ah man, I think my computer ate my report!
Friend: No sweat, go talk to computer guy. I think he lives on second floor of the next hall.
