Working of Machines


                 Similarly, we give instructions to the computer, the computer then works on

                 computer are called input. The working of the computer is called processing

                 and the result we get is called output.

                 Thus, a computer works in three steps:                                                                     WOrkIng Of a cOMPuTer
