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. --This text refers to an out of print or unavailable edition of this title.

This book is required reading for all computer geeks or anyone who wants to know how computers really work.
I honestly had given up on ever finding a book like this- and i'm so glad to know there ARE people out there who want to know how the amazing things around them work!
Most of the explanations are very clear and, since the book starts from the very basic and builds up, it's very easy to understand.
Extremely useful knowledge defined in userfriendly manner that can be understood so easily.Published 6 days ago by AMIN A AZIZ
Charles Petzold was my favorite computer book writer from way back in in the beginning of pc programming. His style is easy and humorous. Read morePublished 6 days ago by J. Ferrara
Great book. Just make sure you have a decent grasp on mathematics. Though if you didn't I don't know why you'd pick this one up anyway.Published 18 days ago by Dylan
Started off ok, and then I went to sleep halfway though. Goes to show why I'm not a developer.
Reminds me of Godel, Escher and Bach, actually. Read more
This book is easy to read and Petzold's storytelling makes this the Freakonomics/The Tipping Point version of computer coding!Published 1 month ago by Brandon Rubenstein
I'm a senior in software engineering, so I was hesitant to invest time in reading a book that seemingly would only result in re-hashing much of what I already studied in college. Read morePublished 1 month ago by Robert Sanek
