It usually covers a broader scope of IT in general, while still going deep enough into certain technologies to land you a very high paying job. The curriculum will also usually give you more choice about what electives you take, so you can determine a focus within the degree. It is usually heavier on programming, software, and computer algorithms while a little lighter on math, circuits, and electronics when compared to EE and ECE.
I always thought of it as a more serious, in-depth BIS or MIS degree. It is a pretty serious degree if you get it at a decent college. More common job offers coming right off a CS degree include any form of programming, computer security engineer, computer forensic analyst, database admin, windows/unix admin, network specialist, network analyst, network engineer, etc. I started off at over $50K/year just 1 month after I graduated college and am now close to $70K/year 2.5 years later in a relatively low-cost area.
