Speakers

                 Speakers are output devices that produce music,

                 speech or other sound from the computer.



                                                                                                Speakers

                    Recap



                         The computer system is made up of two 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.
