Imagine, a machine that doesn’t exist yet. Draw it in your notebook
and write any one of its use.
DIFFERENCE BETWEEN COMPUTERS AND
MACHINES
Other machines can do, only the kind of work, for which they have been made. But
computers can do different types of work.
For example, we all have seen a bicycle. It is a machine. It is used for transportation
from one place to another. It makes our work easier but it cannot do anything other
than transportation. On the other hand, a computer can do a lot of things at the
same time. For example, we can draw a picture and listen to songs at the same time.

A computer cannot work on its own. It needs instructions to per-
form a task.
An abacus is also a machine. It has colourful beads which are used
for counting.
FEATURES OF A COMPUTER
1. Computers work very fast and they don’t
make mistakes.
2. Computers can be used to search for
information.
