"The beauty of computation lies not just in its elegance, but in its ability to transform the abstract into the tangible."

Computers are everywhere --- most obviously in our laptops and smartphones, but also our cars, televisions, microwave ovens, alarm clocks, robot vacuum cleaners, and other smart appliances. Have you ever wondered what goes on inside these devices to make our lives easier but occasionally more infuriating? For more than 20 years, readers have delighted in Charles Petzold's illuminating story of the secret inner life of computers, and now he has revised it for this new age of computing. Cleverly illustrated and easy to understand, this is the book that cracks the mystery. You'll discover what fl ashlights, black cats, seesaws, and the ride of Paul Revere can teach you about computing --- and how human ingenuity and our compulsion to communicate have shaped every electronic device we use. This new expanded edition explores more deeply the bit-by-bit, gate-by-gate construction of the heart of every smart device -- the central processing unit that combines the simplest of basic operations to perform the most complex of feats. Along with new chapters, Petzold has created a new website, CodeHiddenLanguage.com, that uses animated interactive graphics to make computers even easier to comprehend. From the simple ticking of clocks to the worldwide hum of the internet, Code reveals the essence of the digital revolution.
