Okay, it's time to admit it. Even though most of us can run our fingers across a keyboard at lightning speed, create instant messages and e-mail in our sleep, surf the net like pros, and write research papers on white, empty screens, the truth is that a lot of us have no idea how we're able to do this. Our computers are a mystery to us (evidenced by how quickly we go into a meltdown when they don't work right). We may use them every single day and find it difficult to imagine life without them, but most of us haven't a clue as to how they really work.

Where is cyberspace anyway? When you hit the send button, where do your words go—and how do they know how to get there? This lesson will at least give you a working knowledge of some of the most basic computer terms. Maybe they'll help you figure out what to do the next time your computer freezes or the Internet goes down. Maybe they'll just make it easier to explain to that person at tech support just what kind of technical problem you're having. Either way, good luck.
