Hidden Language of Computer Hardware and Software

First published 1999 · 480 pages

A brilliantly patient unraveling of the magic inside our machines, turning complex engineering into a beautifully logical story of human communication.

What it feels like

Reading this book feels like sitting down with an endlessly patient, brilliant friend who is determined to show you that the modern world isn't magic, it's just logic. The experience is incredibly steady and intellectually satisfying, building a towering skyscraper of understanding one perfectly placed brick at a time. It starts with the cozy, playful image of two kids flashing lights across a bedroom window and slowly, almost imperceptibly, guides you into the deep architecture of microprocessors. The prose is conversational and remarkably clear, stripping away intimidating jargon in favor of grounded, everyday analogies. It is a deeply rewarding, mind-expanding read that will delight curious tinkerers, history buffs, and anyone who has ever looked at a laptop and wondered how it actually works.

About the book

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.
