Speakers


            Speakers are output device that  produce  music,
            speech or other sounds, from the computer.




                                                                                           Speakers
               Recap



                    The computer system is made up of two types of parts—Hardware and Software.
                   A computer works on the IPO (Input-Process-Output) cycle.
                   A computer accepts data and instructions through input devices.

                   Processing is done on the data entered into the computer, to convert it into
                  meaningful information.
                   The output devices are used to display the information and result of computation.
