What Does Simulation Mean?
A simulation is any research or development project where researchers or developers create a model of some authentic phenomenon. Many aspects of the natural world can be transformed into mathematical models, and using simulation allows IT systems to mimic the outcomes that happen in the natural world.
Techopedia Explains Simulation
Part of the challenge with a simulation is setting the scope of that simulation. Many natural models are extremely complex, for example, meteorological data models or models of the human mind. Researchers are faced with the challenge of choosing the most important factors in order to build an efficient simulation or model.
