Thus, a computer works in three steps:
                                           INPUT   PROCESS   OUTPUT


            This is process 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
