Thanks for the link, fgdn17. It certainly looks like a much more detailed resource on the subject of a computer's workings than this site provides, but I'm finding myself so far out of the loop I can't find a base of reference. As I read through the pages, I start going through loops trying to understand definitions of what they're describing.
For instance, I'm still failing to comprehend what a 'clock cycle' is relative to memory access.
