Not quite sure if you're talking about the underlying hardware and all. But awhile back I ran across the book "Building a Modern Computer from First Principles". I haven't actually read it due to being in school myself but it seems extremely interesting. Basically it walks you from low level boolean logic up through processor design, compilers, operating systems, and languages. Most of the book can actually be downloaded from their site here: http://www1.idc.ac.il/tecs/plan.html http://www1.idc.ac.il/tecs/plan.html.
