TYPES OF COMPUTERS
There are many types of computers and they come in various sizes. Let us
learn about them.
DESKTOP COMPUTER
A desktop computer is a computer that is kept on a
desk. They are commonly used at homes, schools
and offices. They cannot be moved from one place
to another because of their size and weight.

a desktop computer and can be carried easily from one place to another. It
runs on a battery. We charge the battery of a laptop just like we do that of a
mobile phone.
