Iterations are time-boxed periods during which the team is focused on producing a demonstrable product, some amount of functionality that is ready to be shown to the customer and potentially ready to be delivered. Usually, iterations are 2-4 weeks long. In Scrum, an iteration is called a “sprint.”
In Lean-Agile, teams develop iteratively and release incrementally.
