After calculating, we’ll find that the answer is                Just as ants build a colony
                  15. Similarly,  we give instructions  to  the                   together, computers gather

                  computer, and then the computer works on                        information to help us solve
                  the instructions and gives us the result.                        problems and learn new
                                                                                              things.

                  The working of a computer can be defined by three steps: input, process and
                  output.


                                  INPUT                      PROCESS                        OUTPUT


                     Input:  The  information  or data  given  to  the  computer  is  called  input.
                     A mouse is an example of an input device.

                     Process: The actions performed on the input to convert it into meaningful
                     information (output) is called processing. CPU is the brain of the computer.
                     It performs suitable actions on the input provided.

                     Output: The result of processing is called the output. The monitor shows the
                     result of the work done by the CPU. A monitor is an example of an output

                     device.

                       ▶  A computer works in three steps.

                       ▶  P in IPO stands for Process.
