How do you get information from him? - How
does a computer interact with humans? We
enter data into the computer, but we never
think about the relationship between what
we enter and what the computer processes.
We understand language consisting of letters,
numbers and punctuation marks. However, a
computer can only understand numbers that
consist only of) 0 and 1.(

Input Devices:

Input devices translate the numbers, letters, and commands we understand
into a form that computers can process.

For example, when writing a message on a computer, you use a keyboard to
enter text and a mouse to give commands.

There are a variety of input devices, and below are some of the basic input
devices that are commonly used.
