When we have done out work on a computer, we may want to keep it for future use. In this case, we will have to save our work onto a floppy disk or hard disk and USB. Otherwise our work will be lost when we switch off the computer.
File
If you have done some written exercises on paper, you will probably keep them in a file or a folder.
Similarly, if we want to save our work done on the computer, we can save it in a file on the disk.
A file cam contain report, drawing or a program. Each file should be given a different name so that we can recognize it later.
Retrieving
To make use of the information already saved on to a disk, we have to retrieve it from the disk. This is like playing a cassette tape to listen to music the music.
