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 save it and continue the rest of it
in the next period. What will you do? You will save it.
Many years ago, people used a storage device called Floppy
Disk. It is not used nowadays. The save icon you see in almost
all software is actually an image of a floppy disk.
WHAT IS A FILE?
When you write something in a notebook or draw
something in your drawing book, your notebook
and drawing book are 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
Paint File
disk. A file in a computer is a piece of information
stored on a storage device.
