                                 Your Aim

                                 to learn about:
                                        Working of Machines               IPO Devices





                  Take a look at what is being prepared here.















                               Lemon              Water              Sugar                        Lemonade



                    It’s Lemonade! The things that we put inside the glass are inputs and the lemonade
                  that we got is the output.

                    So, lemon, sugar and water are the inputs and the lemonade that we get after
                  mixing them all is the output.


                  Therefore, the action that takes place with the inputs is known as processing. The
                  results that we get after processing are known as output.


                      WORKING OF MACHINES

                  Similarly, when we give instructions to the computer, the computer then works
                  on the instructions and gives us the result. The instructions that we give to the

                  computer are called input. The working of the computer is called processing and
                  the result that we get is called output.
