• noun an operation in which a computer is made to imitate a real life situation or a machine, showing how something works or will work in the future


  • An imitation, model, or other representation of an object, situation, process, feature, manner of operation, or the like. Such a simulation is intended to faithfully reproduce the real or theoretical objects, situations, processes, and so on, it is based on, and can be used, for instance, for analysis, testing, or training.
  • The use of a computer to imitate an object or process. sophisticated software, combined with accurate input devices, enable a computer to respond mathematically to factors such as changing conditions, as if it were the object or process itself. Such simulations may be used to represent or emulate almost anything, including weather conditions or biological processes, and may be utilized to test new theories. Also called computer simulation.
  • A mathematical model which is utilized to represent a physical component, circuit, device, piece of equipment, system, process, or phenomenon.
  • The use of software and/or hardware which enables programs written for one computer to work properly with another system which would have otherwise been incompatible.

  • (written as Simulation)
    Simulation is an analytical method or model for imitating a real-life system, predicting the course of someone's health or health care costs, etc., usually in order to see the consequences for some variables of changes in their determinants.
