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. Short DesriptionWhat 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 ways to communicate 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. Now in paperback edition, this critically praised book weaves an inventive and eminently comprehensible narrative for anyone who''s ever wondered about the secret inner life of computers and other smart machines. The work of legendary computer book author Charles Petzold has influenced an entire generation of programmers. And with CODE, Microsoft Press is proud to share this gifted teacher and communicator with every reader interested in understanding today''s world of PCs, digital media, and the Internet.
