How a Transistor Actually Works: From Sand to Switch -
RISC vs CISC: The War That Ended in a Tie The instruction-set war of the 1980s and 90s ended in the strangest way possible: both sides won. How x86 swallowed RISC whole, how ARM grew CISC-grade complexity, and why the ISA matters less than the business model wrapped around it.
