For IT you could do Computer Science, Information Technology, Computer Engineering, etc. There's a whole lot of angles you could come at it from too. Would you want to maintain systems or develop them?
If databases interest you, you could be a DBA. If networking interests you, a network engineer. If you want to do development, you can focus on front-end development, back-end development, full-stack, embedded systems, and more. Maybe hardware interests you, so you'd like to be a computer engineer. Computers/IT has a lot of components to it, and even if you find yourself a person that likes to bounce between different things, there's a lot here that you can bounce between. School will have you touch a little bit of everything, and you can find that part you want to specialize in.
