Emulator

Best emulation software for PC

In computing, an emulator is a hardware or software or both that duplicates (or emulates) the functions of one computer system (the guest) in another computer system (the host), different from the first one, so that the emulated behavior closely resembles the behavior of the real system (the guest).

This focus on the exact reproduction of behavior is in contrast to some other forms of computer simulation, in which an abstract model of a system is being simulated.
