Computer Modelling

1.      Model is a thing that allows you to try out many different plans in real life, how would it be like if you change the plan, is it work or not. It's really close to real life situations.Model usually includes formulas, or functions, sometimes it also includes images for more attraction. For example:, you plan on a trip, and you want to create a model to see how much it would cost, if you change the plan, does it work. Or a person who wants to create a company, they would caculate how much it would cost, is it possible to do it?
2.      A model is more simple than a simulation. A model, it helps us to see if our plans work or not. Simulation is also like that, but it's more real life than a model. It's 3 dimensions. People would use simulation to learn how to fly an airplane, to see how people injured in a car crash.
