The Architecture of Computer Hardware, Systems Software, and Networking: An Information Technology Approach 6th Edition

I feel that this book is mostly for programmers, in the way that it is written. If you are looking for a very detailed book this is it. It details how exactly a cpu works, and other components. It is probably a textbook for an IT course. If not, it could be.

Bought it for a class and it works well. Better than buying it online. Good choice when necessary.
