This is the best book i've found on this subject. Reading CODE is like sitting in a well-taught class on the fundamentals of signals and computing.

This book is a true creation of art. It is a must have for anyone who wants to understand how computers work at the lowest of the levels. It starts off with "What is electricity?" and builds up on the design of a truly working modern computer.

Plus, you don't have to be an electrical engineer or have any knowledge on electronics, since the author assumes no previous knowledge on the field. No one but Charles Petzold could have ever written such an amazing master creation aimed at both the knowledgeable individual and the total newbie.

Charles Petzold's writing style is delightful and attractive; it couldn't have been any better. Also as I read further into the bowels of the system, eventually I got these thrilling sensations like "No way anyone could have ever thought about this" or "No way this is possible". The way the text is put together allows for such moments of amazement.

The book is loaded with diagrams. Every single step into the woods is clearly explained and illustrated.

I can't say enough good things about this book. I've recommended it to friends of mine coming from all levels of understanding. Few times have I been as enthusiastic about a book as I have about this one.

CODE is perfect except for the end. For 3/4 of the book, everything is meticulously and wonderfully detailed. However, in the last quarter, Petzold explicitly focuses on limiting his book to a certain number of pages and gives us a whirlwind tour through some really interesting topics. I'd like to see another 1 or 2 books explaining these to the same degree of detail as all of the early chapters.

This book is precisely what the doctor ordered; truly, there is no other book that even comes close to this one, in terms of actually capturing the most elegant, explicit essence of what the computer actually is, and does.

This is the standard that all other computer books must now live up to, and I'm sure that no small number of rival authors are a little green with envy. After all, nine years after its original publication in 1999, this book is #27,439 on Amazon... a score that easily outranks the majority of newer books!

It's a classic. I only hope Petzold does updated and, even, illustrated versions of this book. It is the "Cosmos" and "A Brief History of Time" of the computer industry.

I picked up back on Ch.4 after the bus station stop. Very well done, Charles. A labour of love, indeed, very well crafted. I still don't know if Thevenin's theorem is for pure calculation purposes of being. The two parallel puzzle bc. Exit
