INPUT       →    PROCESS   →  OUTPUT

                  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                               Tech Fact
                  computer are called input. The working                The letters, numbers and symbols

                  of the computer  is called  processing                we give  to  the  computer  are
                  and the result we get is called output.               called data.

                  Thus, a computer works in three steps:


                                        INPUT  →  PROCESS  →  OUTPUT

                  This is also called IPO cycle. Let us look at some more examples of IPO cycle.
