Iteration is the act of repeating a process with the aim of approaching a desired goal, target or result. Each repetition of the process is also called an iteration, and the results of one iteration are used as the starting point for the next iteration. The pentagon on the right also is a good example of how iteration relates to recursion.
While the adjective iterative can be used to describe any repetitive process, it is often applied to any heuristic planning and development process where a desired outcome, like a software application, is created in small sections. These sections are iterations.
