1. what is an icon?

a program
a graphical representation used to launch a program
the text used to launch a program
the operating system

1. what does undo allow users to do?

permanently delete a selection
copy and paste a selection
delete a selection from one document and undo the selection in another document
delete or move a selection in a document and undo or put the selection back if the user changes his or her mind.

Explanation:

• For question 21: An icon is a visual symbol (graphical representation) that when clicked or interacted with, launches a program. It is not the program itself (which is code and data), not just text (as it has a visual element), and not the operating system (which is a software that manages hardware and software resources).
• For question 22: The Undo function allows users to reverse actions like deleting or moving a selection. If a user deletes or moves something in a document and then decides they made a mistake, Undo can put the selection back. It is not for permanent deletion (that would be a delete without an undo - like shift + delete in some systems), not just for copy and paste (which is a different operation), and not for actions across different documents in the way described (undo typically works within the context of the current document's action history).

Answer:

1. a graphical representation used to launch a program
2. delete or move a selection in a document and undo or put the selection back if the user changes his or her mind
