The process of repeating a set of instructions or operations multiple times, typically using loops like for, while, or do-while. Each repetition is called one iteration of the loop.
From Latin 'iterare' meaning 'to repeat,' from 'iterum' (again). The term entered computing in the 1950s to describe the repetitive execution of instructions, maintaining its original meaning of doing something again and again.
Iteration is like washing dishes - you repeat the same process (scrub, rinse, dry) for each dish in the sink. You don't need to know in advance exactly how many dishes there are; you just keep repeating until the sink is empty. That's exactly how a while loop works!
