Mrs. Hinojosa ,  

I think the three basic tasks are this:

     you enter data in the computer

   the data is saved on the computer

 the results are then printed if needed

You enter data in the computer when you need that info. for a job and or something else.

The data is saved on the computer if it is needed again if you lost, or ripped your first one.

The results are then printed if needed at any time if you have saved it on a pin-drive.
