Real-time Computing - History

History

The term real-time derives from its use in early simulation, where a real-world process is simulated at a rate that matched that of the real process (now called Real-time Simulation to avoid ambiguity). Analog computers, most often, were capable of simulating at a much faster pace than real-time, a situation that could be just as dangerous as a slow simulation if it were not also recognized and accounted for.
