You know that a computer cannot function on its own. It needs instructions to

            work. Let us observe how the IPO cycle works in daily life.

            WASHING CLOTHES IN A WASHING MACHINE

            In  this example, dirty clothes and washing powder are the inputs. We are

            washing the clothes as a set of processes. So, washing clothes is the process.
            We get clean clothes as the output.

















                                                            Process
              dirty clothes and washing powder            washing the clothes                clean clothes
                           (Input)                             (Process)                        (Output)


            CALCULATING NUMBERS

            If we are asked to add the numbers 10 and 5.


                                            10           5          +      =    ?


            To add these numbers, we will use our brain to think and calculate.


                           10,5,+                          10 + 5                             15
                            Input                         Process                           Output



            After calculating, we’ll find that the answer is 15. Similarly, we give instructions
            to the computer, and then the computer works on the instructions and gives
            us the result.




                       IPO CYCLE


            The working of a computer can be defined by three steps: input, process and
            output.


                            INPUT                      PROCESS                        OUTPUT
