Imagine yourself a "zero." Or if you prefer, a "one." Tiny as you've just become, you're perfectly sized to go inside your computer, zip from one device to the next, skitter across a network, and ultimately discover how all these technologies work.
Too fantastic a voyage for you? Get How Computers Work instead. Ron White takes you under the hood of virtually every contemporary computer technology, showing you how everything works -- with a major assist from hundreds of full-color illustrations. This Sixth Edition's not merely updated, and not merely bigger: It also includes a CD-ROM containing a "up-close virtual reality tour" of the innards of your PC. (Watch out for that fan!)
How Computers Work illuminates everything related to your PC: processors and memory; disks (including compression and defragging); software and programming languages; DVD players; joysticks, mice, and touchpads; the Web and email; streaming media, LANs, wireless, Palms, color printing, scanning and OCR, speech recognition, uninterruptible power supplies...we could go on. The explanations are exceptionally relevant, accurate, brief, and readable. This is a book that ought to be in every library. Starting with yours.

"Any sufficiently advanced technology is indistinguishable from magic."
Arthur C. Clarke
SORCERERS have their magic wandspowerful, potentially dangerous tools with lives of their own. Witches have their familiarscreatures disguised as household beasts that could, if they choose, wreak the witches' havoc. Mystics have their golemsbeings built of wood and tin brought to life to do their masters' bidding.
We have our personal computers.
PCs, too, are powerful creations that often seem to have a life of their own. Usually, they respond to a wave of a mouse or a spoken incantation by performing tasks we couldn't imagine doing ourselves without some sort of preternatural help. But even as computers successfully carry out our commands, it's often difficult to quell the feeling that there's some wizardry at work here.
And then there are the times when our PCs, like malevolent spirits, rebel and open the gates of chaos onto our neatly ordered columns of numbers, our carefully wrought sentences, and our beautifully crafted graphics. When that happens, we're often convinced that we are, indeed, playing with power not entirely under our control. We become sorcerers' apprentices, whose every attempt to right things leads to deeper trouble.
Whether our personal computers are faithful servants or imps, most of us soon realize there's much more going on inside those silent boxes than we really understand. PCs are secretive. Open their tightly sealed cases and you're confronted with poker-faced components. Few give any clues as to what they're about. Most of them consist of sphinx-like microchips that offer no more information about themselves than some obscure code printed on their impenetrable surfaces. The maze of circuit tracings etched on the boards is fascinating, but meaningless, hieroglyphics. Some crucial parts, such as the hard drive and power supply, are sealed with printed omens about the dangers of peeking insideomens that put to shame the warnings on a pharaoh's tomb.
This book is based on two ideas. One is that the magic we understand is safer and more powerful than the magic we don't. This is not a hands-on how-to book. Don't look for any instructions for taking a screwdriver to this part or the other. But perhaps your knowing more about what's going on inside all those stoic components makes them a little less formidable when something does go awry. The second idea behind this book is that knowledge, in itself, is a worthwhile and enjoyable goal. This book is written to respond to your random musings about the goings-on inside that box you sit in front of several hours a day. If this book puts your questions to restor raises new onesit will have done its job.
At the same time, however, I'm trusting that knowing the secrets behind the magician's legerdemain won't spoil the show. This is a real danger. Mystery is often as compelling as knowledge. I'd hate to think that anything you read in this book takes away that sense of wonder you have when you manage to make your PC do some grand, new trick. I hope that, instead, this book makes you a more confident sorcerer.
