Controlling a Computer Simulation
Many computer simulations contain a control system that triggers responses depending on what keys have been pressed on a keyboard. For example, in a racing car simulation:


This flowchart describes how the control program will decide what to do with the car (the actuator):


When the computer carries out these instructions it is said to be executing or running them.

In this example, three sets of instructions run at the same time. This is called parallel execution.
