the universe's favorite way of turning questions into answers, one tiny step at a time.
means a step-by-step process that transforms input into output following fixed rules, whether run by silicon, neurons, or an abacus.
from from latin computare, to reckon together — com (with) plus putare (to reckon or prune) — literally trimming a problem down to a number.
