CODE. The Hidden Language of Computer Hardware and Software

Electricity is like nothing else in this universe, and we must confront it on it’s own terms

Charles Petzold does an amazing job in this book. It explains how current computers work without a previous knowledge required. While there was no new information for me at all, I really enjoyed the way it presents the concepts, easy and with a lot of clarifying pictures. Is one of those books that you can say “I wish I read this book while I was studying the topic”.

Some argue that it has no relevance at all because it is old (1999). I would respond that while the computer world seems to advance very fast, the bases are almost the same, (1945 First Draft of a Report on the EDVAC), but with a lot of refinement (smaller, faster, smarter).

This book is a must-have if you want to learn how a computer works and you don’t feel like reading very technical stuff.
