Microphone

                  A microphone is an input device that is used to record voice, music
                  and sounds. These can be stored on the computer.

                                                                                                         Microphone
                   i +   PROCESSING DEVICE

                  The device that works on the input is called processing
                  device. CPU is the main processing device.
                  CPU stands for Central Processing Unit. It works

                  like the brain of a computer. CPU is fixed inside the
                  CPU box/Cabinet.

                                                                                     CPU            CPU Box/Cabinet
                   i +   OUTPUT DEVICES
                  The devices which help us get the results are called output devices. Some of the
                  commonly used output devices are monitor, printer, headphones and speakers.


                  Monitor

                  A monitor is an output device that looks like a television screen.
                  It is also known as the Visual Display Unit or VDU.

                  The front portion of the monitor is called the screen.
                  The monitor shows you the data that you input and its
                  result after the computer processes it.                                                Monitor


                                                      Printer

                                                      A printer is an output device used to print the result
                                                      of the work done by the computer on paper. There

                   Inkjet Printer    Laser Printer    are two types of printers:
                                                      •  Inkjet printer                 •  Laser printer


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



                  Speakers

                  Speakers are output devices that are used for
                  listening to music, voice and sound on a computer.

                                                                                                         Speakers
