Chances are you’re reading this book because you have a new computer. At this point, you might not be totally sure what it is you’ve gotten yourself into. Just what is this mess of boxes and cables—how does it all go together, and how does it work?

You should note, however, that no two computer systems are identical because you can always add new components to your system—or disconnect other pieces you don’t have any use for. And notebook computers are a bit different from desktop models, even though they do the same thing; the parts are just assembled a little differently.
