Scanner

                                 Scanner is an input device that is used to send documents or images
                                 from the paper to the computer. It works like a photocopier machine.



              Microphone

              Microphone is an input device which is used to record voice, music
              and sounds. These recordings can be stored on the computer.


                    PROCESSING DEVICE

              CPU is the processing device. It processes the input according to the
              instructions we give and returns the output to the output devices.

              It also manages all the work of a computer. The CPU is inside the                      CPU
              CPU box/cabinet.                                                                       116245 3836 975588

                    OUTPUT DEVICES

              The devices through  which  we get the result or output  after processing are called

              output devices. Let us study about some of them.

              Monitor

              Monitor is an output device that looks like a television screen.

              It is also known as Visual Display Unit or VDU. It displays all
              the work done on a computer.

              The front portion of the monitor is also called the screen.


                                                       Printer

                                                       Printer is an output device. It  is used  to print  the
                                                       result of the work done by the computer on a paper.

                The result we get on the monitor screen is called soft copy and the result we get on paper
                is called hard copy.




                                 If you could go inside a computer and see how it processes information,

                                 what do you think you would see? What kind of tiny creatures or machines
                                 might be working inside?
