"You've got mail!" The phrase has become part of our everyday lexicon, a new signpost of popular culture, one that defines an era, much like "I am not a crook" or "I can't believe I ate the whole thing."
Today, a wired America, physically and emotionally, communicates on-line. We have taken Morse code to a new extreme. We can send the equivalent of a library full of information around the globe in bits and bytes, a form of dots and dashes, as fast as energy can move through wires. None of this would be possible, of course, without computers, which provide the backbone of the Internet, the telephone systems, and just about every other mode of communication, transportation, commerce, and government. The computer today has become the heart and lungs of our society, powering and sustaining our lives efficiently and safely . . . until it crashes.
