                                                images from the paper to the computer. It works like a

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

                                                                                                     Microphone
                     OUTPUT DEVICES

                 The devices through which we get the result or output after processing are called
                 output devices. Some of the output devices are:

                 Monitor


                 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 the data that you input and its result after
                 the computer processes it.
                                                                                                     Monitor
                 Printer

                 Printer is an output  device used to

                 print the result of the work done by the
                 computer  on  a  paper.  There  are  two
                 types of printers:

                    Inkjet printer
                    Laser printer                                           Inkjet Printer           Laser Printer







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