emulation
(architecture)When one system performs in exactly the same
way as another, though perhaps not at the same speed. A
typical example would be emulation of one computer by (a
program running on) another. You might use an emulation as a
replacement for a system whereas you would use a simulation if
you just wanted to analyse it and make predictions about it.

Hardware, software or a combination of the two that enables a computer to run programs for another platform. In the past, an emulator was hardware, and a "simulator" was software.

For example, Apple's iOS "simulator" and Google's Android "emulator" are both software utilities that run their respective mobile apps in the computer for testing purposes.An Emulator Is a Translator
