Where I'm at, here's how it goes:
College of Science and College of Business Administration are the two key colleges for IT. College of Engineering is another field as that gets into Computer Engineering which is all hardware (diodes, resistor, digital logic, AC/DC. etc). It's hard, because you actually design the components (motherboards, IC's-CPU-GPU, etc.)
College of Science includes computer science while the College of Business Administration includes CIS (Computer Information Systems). In the Computer Information Systems field, it is further divided into 4 different tracks:
Applications Software Development
Business Systems Analysis
Internet Programming and Security
Telecommunications and Networking
You pick one you want to do and that's it. Computer Science is a whole other field and I won't get into that. It's using C++, Fortran, and other different programming languages. It's strictly programming and software development (hardcore stuff).
With CIS, you're an IT with a broad knowledge of C++, Java, HTML, etc. so you are exposed to some Computer Science classes.
