What is an "icon"?
You will learn what an icon is in plain words.
An icon is a small picture you tap to do something.
Each one stands for an app or a button. The picture hints at its job.
For example, a tiny camera icon opens the camera. A trash can icon deletes.
You tap an icon instead of reading a lot of words. That is an icon.

If you are unsure what an icon does, tap and look. You can go back.
