This one's for you if you want to learn or just recap principles of computers (and read on evolution as well). I just started reading it and found it suprisingly easy to follow. It's perfect if you like things explained step-by-step and in a simple way.
However, I bought this book in 2013 and was disappointed. I kept the book in the hopes that my high school and college aged kids might get something out of it. This is a book appropriate for someone new to programming. I don't consider this a book for computer scientists that already have a university degree, since it provides only a very basic introduction to Boolean algebra, logic gates, computer arithmetic. If you know what a NAND gate is and what a XOR instruction does you don't need this book.
For the practicing professional or a serious CS student interested in bits and bytes I might recommend Hackers Delight, Second Edition by Hennry S. Warren Jr.
Definitely would recommend!
