How storage is layered from registers down to disk. Why DRAM is slow. What cache is actually for. How virtual memory hands every process a private view of the machine and enforces it in hardware. Then the CPU itself, what it does with an instruction and which registers you need to recognise. Then the stack, where the first two meet.</p>
