                 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:









                                                Keyboard           Mouse





                                          Give two examples of input devices.

                 PROCESSING DEVICE


                 Processing device usually works on the input. A CPU
                 is the processing device of a computer. CPU stands
                 for Central Processing Unit.



                 OUTPUT DEVICES                                                            CPU          CPU box

                 Output devices show the result of all the work done on the input. The result is

                 called the output.

                 Some output devices are:











                                Monitor               Printer            Speakers
