Computers covers a pretty broad field from hardware to software to communications to tech support to installations to database/datamining to integration of technologies and so on. There are many ways to go in the technology field.

I was an astronomy major at college/uni and had to take a computer programming course as a degree requirement. I loved it and was bitten by the bug. My degree was in astronomy but my career was in software development. It is funny how life throws you unexpected curves when you least expect it.
