                  Need for Storing Work on a Computer

                  When your teacher teaches you something, you keep it in your
                  brain and recall it when required. But you may forget it sometimes.
                  But if you note it down in your notebook, you can revise it later,
                  again and again. So whatever you have learnt remains forever.

                  In the same way,  when you work  on your  computer and if the
                  electricity goes off, you will lose all your work. And when you restart
                  your computer, you will not be able to open the same work again.

                  But if you save it on any of the storage devices, you can open
                  your  work again.  Storing work  on a computer  on any storage
                  device is called saving.

                  Suppose you are drawing a ‘Rainy scene’ in Paint. You
                  have finished half of it and your computer period is over.
                  You want to continue to work on it in the next period.
                  What will you do? You will save it.



                     Info Byte
                      Many years ago, people used a storage device called Floppy
                      Disk. It is not used nowadays. The save icon you see in
                      almost all the software is actually an image of a floppy disk.






                   i +  WHAT IS A FILE?
                  When you write something in a notebook or draw

                  something in your drawing book, your notebook and
                  drawing book act like files.

                  When you work on a computer in any software and
                  save it, it gets saved in the form of a file on the hard
                  disk. A file in a computer is a piece of information                                    Paint File
                  stored on a storage device.
