                  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  is  the
                  output.

                  Therefore, the action that takes place with the inputs is known as processing. The

                  results that we get after processing is known as output.


                         WORKING OF MACHINES


                  Similarly, 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 we
                  get is called output.
