The basic element in a computer can be an electromagnetic relay, a vacuum tube, or a transistor.All three of these can function as switches which are electrically controlled.A computer can use small and cheap vacuum tubes or transistors; while its components need to be reliable, they don't need to be high-quality in all respects. One transistor logic family, ECL (emitter-coupled logic), used in many of the highest-speed computers, takes advantage of the fact that a transistor can respond more quickly to its input if it does not have to go all the way from a fully-on state to a fully-off state.
