Ok, so if you're not so tech savvy; and you want to 'get with it' there's actually a lot of ways you can go about it. Me, I didn't really 'grow up' with a computer...I got one when I was about 15 or so and kinda winged it for a while. Basically, it depends on your background too. Hehe...I feel I'm qualified to give advice because I've done just about all these things!
Self instruction: I can't knock it too much, because I did it. But if you're working a full-time job with other responsibilities than your computer, expect the progress to be slow. The good part is that there are no shortage of books for computers. The bad part is that there are no shortage of books for computers (if you catch my drift).
Community Colleges: These places are great (just as long as you don't tell too many of your friends you're attending). The tuition for the courses are rock bottom and often time teach more current skills and provide "fast-track" programs to teach you just what you need to know to put on your resume or for that job promotion. They also often have night & weekend classes. The downside is that because the education isn't so general (like in computing theory, math, etc.) so you might be pigeonholed.
Private instruction: Hmmmm...why am I thinking about The Graduate here? Anyway, I've never heard of anyone doing or receiving this...although it sounds like a killer idea. It might be expensive though. This seems like this would be a better idea if you already knew a program and just needed some more 'pointers' to help you along.
Tech Schools (like ITT): These places turn you from novice to professional in like 1 or 2 years. When you get out, you know your stuff! Some programs are even geared towards a certain certification (like A+, or MSCE). The bad side, is that you never know how employers will view you. Some look at tech schools as 'substandard' and not able to diversify in the workplace (so that's why they hired the psychology major who only took 'Intro to Computers'). But that's not all of them. Also career schools like this aren't the place to go if you're just looking to pick up a thing or two. Lot's of times, the tuition at these places rival full-fledged universities...without all the financial aid availability. So tread with caution!
Traditional College: You'll have more versatility if you go this route in the long run. Immediately though, you might get disillusioned. Computer Science (and Computer Information Technology) programs are not as rigorously defined as say engineering programs. Some schools will have you take a lot of courses in math and logic. C++ is about as current a programming language as you'll touch at other schools. Compare the course sequences, requirements and outlines. Also, Computer Science is about the theory of computing and (sometimes) software engineering. Computer Information Technology involves more application use and learning a variety of skills needed to make a computer system/network run or implement one from scratch. Sometimes the 'Computer Science' program can be affiliated with the college of arts & sciences, college of engineering, or business school, or even stand alone. Keep in mind, the parent school will determine your prerequisites. With college being as long, and tedious and unfocused as it is, it's obviously not an option for everyone.
Certifications: I don't have any of these, but in many jobs they seem necessary. Especially if you don't have a degree or degree wasn't in a computer related field. Check local papers for seminars for people taking the test. They can seem pricey ($500 sometimes) but I hear it's worth it and most college classes cost more that that (and they don't help you with certifications).
I guess computers are fun like that because they always force you to learn. The basics never change though. Which is good. I learn fast, but I do get set in my ways!
