Simulation

n. act of pretending; imitation, counterfeit; imitation of the operation or features of one system using another system (i.e. computer simulation)

A simulation is an imitation of some real thing, state of affairs, or process. The act of simulating something generally entails representing certain key characteristics or behaviours of a selected physical or abstract system. Historically, the word had negative connotations: …for Distinction Sake, a Deceiving by Words, is commonly called a Lye, and a Deceiving by Actions, Gestures, or Behavior, is called Simulation… Robert South (1643–1716) However, the connection between simulation and dissembling later faded out and is now only of linguistic interest.
