Amazon.com Review

Charles Petzold's latest book, Code: The Hidden Language of Computer Hardware and Software, crosses over into general-interest nonfiction from his usual programming genre. It's a carefully written, carefully researched gem that will appeal to anyone who wants to understand computer technology at its essence. Readers learn about number systems (decimal, octal, binary, and all that) through Petzold's patient (and frequently entertaining) prose and then discover the logical systems that are used to process them. There's loads of historical information too. From Louis Braille's development of his eponymous raised-dot code to Intel Corporation's release of its early microprocessors, Petzold presents stories of people trying to communicate with (and by means of) mechanical and electrical devices. It's a fascinating progression of technologies, and Petzold presents a clear statement of how they fit together.

The real value of Code is in its explanation of technologies that have been obscured for years behind fancy user interfaces and programming environments, which, in the name of rapid application development, insulate the programmer from the machine. In a section on machine language, Petzold dissects the instruction sets of the genre-defining Intel 8080 and Motorola 6800 processors. He walks the reader through the process of performing various operations with each chip, explaining which opcodes poke which values into which registers along the way. Petzold knows that the hidden language of computers exhibits real beauty. In Code, he helps readers appreciate it. --David Wall

Topics covered: Mechanical and electrical representations of words and numbers, number systems, logic gates, performing mathematical operations with logic gates, microprocessors, machine code, memory and programming languages.

Product Description

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.

As good as it gets!

I read this book only because Joel Spolsky had recommended it for anyone who wants to learn programming. In this book, Charles Petzold gives a lucid explanation of how a computer works. He takes you on an exciting journey, through Braille Code, Morse Code, Telegraph Relays, Logic Gates, Flip-Flops, seamlessly from one to the other, each revealing a powerful concept. He slowly puts these together in a stunningly beautiful manner to assemble a computer. The final result is simple yet enough to have a good understanding of computer architecture.

Incidentally, last year I had taken an online course on coursera, based on The Elements of Computing Systems, which helps you build a computer from basic principles. In my humble opinion if Code is theory, then The Elements of Computing Systems is its practical.

The author never forgets to mention the geniuses who laboured to advance the field of computers. This book is essential reading for anyone who is curious about what happens beneath the hood.

Very good book which explains how a computer works. Starts from the initial simple codes like Morse Code, Braille code etc - and explains how those evolved into modern computer binary codes. Logic gates, relays etc beautifully explained. Even a child of age 14-18 can read and understand basics of electronics and computer programming by reading this book.

If you are interested in technology and want to improve your understanding of how computer technology works, a must read for you.
