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.
