n., The reproduction of the behaviour and results of obsolete software or systems through the development of new hardware and/or software to allow execution of the old software or systems on future computers. Syn.: preservation emulation.
-
n., A process of imitation, which is a frequent feature accompanying competition. Customs, buildings, and artifacts in one society may be adopted by neighbouring ones through imitation, which is often competitive in nature.

n., Emulation should be more than simulation. This should mimic exactly the behaviour of the circumstances that it is emulating.

n., The exact execution on a given computer of a program written for a different computer, accepting the identical data and producing the identical results. Emulation is thus the imitation of all or part of one computer system by another system. It may be achieved by software, microprogram, or hardware. A particular emulation could be used as a replacement for all or part of the system being emulated, and furthermore could be an improved version. For example, a new computer may emulate an obsolete one so that programs written for the old one will run without modification.

n., The use of one system to reproduce the behaviours and results of another system.

-
n., 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.
