                  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 might 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, if the electricity goes off while you’re working on
                  your computer, you might lose your work. And when you restart
                  your computer, you will not be able to see the same work again.

                  But if you save it on any of the storage devices, you can see 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 and save your work
                  it gets saved in the form of a file on the hard disk. A
                  file in a computer is a piece of information stored on                                  Paint File
                  a storage device.
