                 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.
