Monitor

                                                A monitor looks like a television. It is also known as a Visual
                                               Display Unit or VDU. The monitor shows the data that you input
                                               and its result (output) after the computer processes it.





                  Speakers

                  Speakers are used to hear music, voice and sound on a computer.




                                               Headphones

                                                 Headphones are used  to  listen  to  music  and sound  without
                                               disturbing others as they are worn by an individual. But wearing
                                               them for a long time can affect your hearing power and cause
                                               damage to your ears.


                  Printer

                  A printer is used to print the result of the work done by the computer on paper. We can
                  print documents, drawings, images, etc. in black & white as well as in colour using a printer.
                  There are two types of printers.


                  Laser Printer

                  It uses a laser beam to print the hard copy.




                                               Inkjet Printer

                                               It sprays ink on the paper to print the hard copy.






                  Plotter
                  A plotter is used to print big sketches, diagrams and maps on long
                  sheets of paper. These are used by engineers, architects, scientists
                  and designers.



                                               Projector

                                               A projector projects or displays data of computer screen on a
                                               large screen or surface for audience. The image shown by the
                                               projector is larger in size then shown on the monitor.
