The classic guide to how computers work, updated with new chapters and interactive graphics "For me, Code was a revelation. It was the first book about programming that spoke to me. It started with a story, and it built up, layer by layer, analogy by analogy, until I understood not just the Code, but the System. Code is a book that is as much about Systems Thinking and abstractions as it is about code and programming. Code teaches us how many unseen layers there are between the computer systems that we as users look at every day and the magical silicon rocks that we infused with lightning and taught to think." - Scott Hanselman, Partner Program Director, Microsoft, and host of Hanselminutes 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 flashlights, 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 and 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. Petzold's companion website, CodeHiddenLanguage.com, uses animated graphics of key circuits in the book to make computers even easier to comprehend. In addition to substantially revised and updated content, new chapters include: Chapter 18: Let's Build a Clock! Chapter 21: The Arithmetic Logic Unit Chapter 22: Registers and Busses Chapter 23: CPU Control Signals Chapter 24: Jumps, Loops, and Calls Chapter 28: The World Brain From the simple ticking of clocks to the worldwide hum of the internet, Code reveals the essence of the digital revolution.

The Book That Started It All Hardcover

The Creator sat upon the throne, thinking. Behind him stretched the illimitable continent of heaven, steeped in a glory of light and color; before him rose the black night of Space, like a wall. His mighty bulk towered rugged and mountain-like into the zenith, and His divine head blazed there like a distant sun. At His feet stood three colossal figures, diminished to extinction, almost, by contrast -- archangels -- their heads level with His ankle-bone. When the Creator had finished thinking, He said, "I have thought. Behold!" He lifted His hand, and from it burst a fountain-spray of fire, a million stupendous suns, which clove the blackness and soared, away and away and away, diminishing in magnitude and intensity as they pierced the far frontiers of Space, until at last they were but as diamond nailheads sparkling under the domed vast roof of the universe. At the end of an hour the Grand Council was dismissed. They left the Presence impressed and thoughtful, and retired to a private place, where they might talk with freedom. None of the three seemed to want to begin, though all wanted somebody to do it.
