(Explained for Grade 3)

Computers and other digital devices help us do many things.
They can store, print, capture, and help us interact.

Let’s learn each one clearly ๐Ÿ‘‡

๐Ÿ‘‰ Just like you keep your toys in a box.
๐Ÿ‘‰ Or you keep your books in your school bag.

Computers also keep things safely.

  • When you take a photo, it is stored in your phone.

Devices that store:

  • ๐Ÿ’ป Computer

  • ๐Ÿ“ฑ Tablet

Simple Example for Kids:

Ali writes a story in the computer.
He clicks Save.
Now the story is stored.
He can open it tomorrow again!

What does “print” mean?

To print means to take work from the computer and put it on paper.

๐Ÿ‘‰ Like taking a picture from inside the computer and making it come out on paper.
