Feedback

This occurs when the outcome has an influence on the input.

Think of a non-ICT scenario:

You are competing in pop-idol competition.

	First of all you provide an INPUT - You sing your heart out.
	The judges PROCESS the INPUT – they consider your talent
	The judges provide an OUTPUT – they give you a score.
	The judges then go on to tell you where things went well (and what didn’t go well) this is FEEDBACK.
	Having taken in the FEEDBACK, in the next round, you sing even better.
