When we hear a question with our ear the input is received by the brain and the

                  brain processes it. It then orders the mouth to speak the final answer. Therefore,
                  our ears act as an input unit, the brain acts as a processing unit and the mouth
                  acts as an output unit.

                  These parts work  together  to help us do                   problems and learn new things.

                  Input Devices


                  The devices that are used to enter data into a computer are known as input devices.
                  The most commonly used input devices are keyboard, mouse and microphone.

                  Processing Device

                  The device that  works  on the input is called a

                  processing device.  CPU is the main processing
                  device. CPU stands for Central Processing Unit. It
                  works like the brain of a computer. CPU is fixed inside
                  the CPU box/cabinet.

                  The devices which help us to get the results are called
                  output devices. The most commonly used output devices are monitor, speakers,
                  headphones and printer.
