Paperback Edition What do flashlights, the British invasion, black cats, and seesaws have to do with computers? In CODE, they show us the ingenious ways we manipulate language and invent new means of communicating with each other. And through CODE, we see how this ingenuity and our very human compulsion to communicate have driven the technological innovations of the past two centuries. Using everyday objects and familiar language systems such as Braille and Morse code, author Charles Petzold weaves an illuminating narrative for anyone who s ever wondered about the secret inner life of computers and other smart machines. It s a cleverly illustrated and eminently comprehensible story and along the way, you ll discover you ve gained a real context for understanding today s world of PCs, digital media, and the Internet. No matter what your level of technical savvy, CODE will charm you and perhaps even awaken the technophile within.
