In computing, an emulator is hardware or software or both that duplicates (or emulates) the functions of a first computer system (the guest) in a different second computer system (the host), so that the emulated behavior closely resembles the behavior of the real system. This focus on 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. For example, a ...

In computing, an emulator is hardware or software or both that duplicates (or emulates) the functions of a first computer system (the guest) in a different second computer system (the host), so that the emulated behavior closely resembles the behavior of the real system. This focus on 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. For example, a computer simulation of a hurricane or a chemical reaction is not emulation.
Emulation refers to the ability of a computer program in an electronic device to emulate (imitate) another program or device. Many printers, for example, are designed to emulate Hewlett-Packard LaserJet printers because so much software is written for HP printers. If a non-HP printer emulates an HP printer, any software written for a real HP printer will also run in the non-HP printer emulation and produce equivalent printing.
A hardware emulator is an emulator which...
