WORKING OF A COMPUTER

                  Computers works on the Input-Process-Output cycle, also known as the IPO cycle.


                                    INPUT                     PROCESS                      OUTPUT



                  You have learnt that a computer works on the principle of Input, Process and Output.
                  Let us explore these in more detail.

                  Input

                  Input means giving instructions to the computer using numbers, letters, or symbols.
                  We use input devices, like the keyboard and mouse to do this.










                                                     Keyboard                          Mouse


                  Process


                  After the computer gets the input, it uses the
                  Central Processing Unit (CPU) to work on it. The
                  CPU is like the brain of the computer and does all

                  the calculations.
                  Output                                                              CPU Box                CPU

                  Output  is  the result we see after  the

                  computer has processed the information.
                  We see this result on output  devices

                  like  the monitor and printer.  With this,
                  we understand that a computer is  an
                  electronic  machine that  takes in input,
                                                                                 Monitor                  Printer
                  processes it, and then shows us the result.
