What is a Simulator?

• A simulator is a computer program which mimics both:

  • the internal behavior of a real-world system
  • the input processes which drive or control the simulated system

• The simulator output is a set of measurements concerning the observable reactions and performance of the system.

Measurements are only estimates of what the real-world measurements actually are / would be.

Why?

Because an abstraction of the real-world system is simulated!
