Feedback Loop
In a loop structure, the program asks a question, and if the answer requires an action, it is performed and the original question is asked again until the answer is such that the action is no longer required. For example, a program written to compute a company’s weekly payroll for each individual employee will begin by computing the wages of one employee and continue performing that action in a loop until there are no more employee wages to be computed, and only then will the program move on to its next action.
Model
A representation, generally in miniature, to show the construction or appearance of something.
Simulation
Imitation or enactment, as of something anticipated or in testing.
