                  The instructions that  we  give  to  the  computer                    Tech Fact
                  are called input. The working of the computer is
                  called processing and the result we get is called     The letters, numbers, symbols we give to
                  output.                                               the computer are called data.

                  Thus, a computer works in three steps:




                                       INPUT  →  PROCESS  →  OUTPUT
