Computer Modelling

     What is model, why it is used, differences between a model and simulation?
_ Model allows you to test out different situations and risks in real life without actually doing it. Model is close to real life depends on how careful it was built. Model can be very simple or super complex depends on the scenarios. People used model because it is less expensive, they can avoid real life risks, and change the formulas. For example, we can plan a field trip, building a house, making a party using model. Model is setup based on various rules and formulas, while simulation is used to test out the consequences based on how the model is created.

An example of simulation model.
