From bulb to C# — how does computer work?
summary
Starts with light bulbs and switches to build AND/OR/NOT gates, then composes XOR, half and full adders, a clock oscillator and a set-reset flip-flop to make RAM; replaces bulbs with the transistor (npn) and explains semiconductors, then shows how gates form ALU, instruction decoder and bus. Covers Von Neumann vs Harvard, x86 → amd64 history, microcode → machine code → assembly → OS APIs → JIT → CLR pipeline, and notes how these concrete pieces scale into a computer capable of running the CLR.
