Input: The information or data given to the computer is called input. A
                     mouse is an example of an input device.

                   Process: The actions performed on the input to convert it into meaningful
                     information (output) is called processing. CPU is the brain of the computer.
                     It performs suitable actions on the input provided.

                   Output: The result of processing is called the output. The monitor shows
                     the result of the work done by the CPU. A monitor is an example of an

                     output device.

                           COMPUTER DEVICES


                 The part of a computer that does a particular job is called a computer device.
                 A computer consists of the following devices:

                   Input devices                         Processing device                    Output devices


                 INPUT DEVICES

                 Input devices give instructions to the computer. Some input devices are:
