A beautifully written journey that makes the abstract concepts of computer science tangible and understandable. Charles Petzold takes readers from Morse code and Braille to modern computers, explaining how computers work from the ground up. The book starts with simple electrical circuits and builds to complex processors, showing how binary numbers, logic gates, and memory work together to create the computers we use every day. Petzold's writing is clear and engaging, making complex topics accessible without dumbing them down. The book covers everything from how relays and switches work to how CPUs execute instructions, how memory stores data, and how operating systems manage resources. This book is essential reading for any developer who wants to understand the fundamental principles underlying the technology we work with every day. It's particularly valuable for developers who work with low-level systems, embedded programming, or performance-critical applications.
