While not universal, I do recommend Charles Petzold's _Code_:

which covers things down to a quite low-level and was recently updated:

This is written for young people, but still accurate: Code: The Hidden Language of Computer Hardware and Software by Charles Petzold

It's got a very slow, methodical onramp with a lot of diagrams and a light, breezy style. You end up building a (very simple) computer in the end, including instruction processing.
