Computers need data to work with, but that data must be represented in a specific way for the computer's hardware to accept and understand them.When you type on a keyboard,and the information appears on the monitor, the information passes from the input device to the output device in a manner that is probably not what you expect.The letter you type is passed to the system by units of information called bits.A bit (binary digit) is the smallest piece of data a computer can process usually 0 and 1. In general when you write your name as John,the computer does not know you are john but know your name as zeros and ones;the bits.
