Emulator

If a flight-simulator could transport you from A to B then it would be a flight-emulator.

An emulator can replace the original for real use.

A Virtual PC emulates a PC.

A simulator is a model for study and analysis.

An emulator will always have to operate close to real-time. For a simulator that is not always the case. A geological simulation could do 1000 years/second or more.

Virtual PC does not emulate, it virtualizes. QEmu, on the other hand, does emulate. In both cases, the name should be a hint. – Jörg W Mittag Oct 18, 2009 at 12:36
