Thus, a computer works in three steps:

                                                INPUT   PROCESS   OUTPUT

                 This process is called IPO cycle.


                 Let us look at some examples of IPO cycle.



                                                                    Process






                                Input
                                                                                                     Output











                            Dirty clothes                      Washing Machine                    Clean clothes





                                Input                             Process
                                                                                                  Output












                            Fresh fruits                          Juicer                        Fresh juice



                 Now, take an example of our human body to understand the same.


                      Input:                                                                            Output:
                   What is 2x2=?                    2x2=4                                             Answer is 4









                                  Input Unit                Processing Unit            Output Unit



                                                                                     Working of a Computer        21
