ClarkeSORCERERS have their magic wands--powerful, potentially dangerous tools with lives of their own. Witches have their familiars--creatures disguised as household beasts that could, if they choose, wreak the witches' havoc. Mystics have their golems--beings 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 inside--omens that put to
