emulation

[‚em·yə′lā·shən]
(computer science)
Imitation of one computer system by another so that the latter functions in exactly the same way and runs the same programs.

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.
