I learned all about how computers work in a couple semesters at university; it was one of my favorite courses. But it took a long time for the cache-related parts to really click, probably because I've spent most of my time writing code (C++ code, even) which was constrained by I/O and system calls. Now that I'm doing more CPU-intensive stuff where DRAM is the incredibly slow bottleneck, all those memories of caches and pipelining have been a huge help in understanding articles written from a practical C/C++ perspective.
