Imagine, you have a magical input device that can take any object from the
                                   real world and put it into your computer. What would you put in, and what
                                   would you want the computer to do with it?



                 HOW COMPUTER WORKS?

                 A computer works in three steps:

                 1.  We give  values and instructions  to the computer. This is the
                   input.
                 2.  The computer then works on the instructions. This is the process.
                 3. Then, it gives us the result. This is the output.

                 For example,

                           5, 10, add                            5+10                                  15

                             INPUT                             PROCESS                              OUTPUT
                 given through an input device       done by the processing device      displayed on the output device


                 A computer uses its input devices (such as keyboard and mouse), processing device (CPU)
                 and output devices (such as monitor and printer) to follow each stage of the IPO cycle.

                   The letters, numbers, and symbols we give to the computer are called instructions.

                    Go to the computer lab with your teacher. Identify the input devices, processing device
                    and output devices of the computer and write their names.
