DefinitionA simulator (シミュレーター) is a system that reproduces real equipment or events on a computer, used to train operators and to verify outcomes.
ExplanationSimulators are used when the real thing would be too dangerous or costly, or when rare situations are hard to set up. By recreating a cockpit and its surroundings in 3D and changing the state as the user operates it, they let people repeat a near-real experience safely. Typical uses include flight and driving training and rehearsing how to respond when a machine breaks down.
AnalogyIt is the same idea as running full rehearsals again and again in a hall set up with the same scenery before opening night.
Memory hookThe word comes from 'simulate', meaning to imitate.
