A computer is an electronic device that process data, converting it into information that is useful to people.
A computer is controlled by the programmed instructions, which give the machine a purpose and tell what to do.

It converts data into information
Modern computers are digital ◦ Two digits combine to make data
Older computers were analog ◦ A range of values made data

The material provided to the device for processing and produce a useful information is called “Data.”
Basically the input part provides Data to the system.
It can be of any type: text, voice, pointer movement etc

The people who interact with the system are “Users”.
We usually instruct according to the requirement of the user, so the users are the most important factor in building a system.
