                      DEVICES OF A COMPUTER


            As you know, a computer works in three steps: input  process  output.

               Input is any data or instruction entered into a computer. The input devices help us enter data
              and give commands to the computer.

               Process refers to the work done by the computer with the help of the processor.

               Output refers to the result that has been processed by the CPU.
            We use different devices for each step. Let us learn about these devices in detail.


            INPUT DEVICES

            We have already read about some of the commonly used input devices in earlier classes. Let us
            now learn about a few more here.
