Laser Printers: These use a  laser  beam  to  produce
                                            high-quality prints by transferring toner onto the paper.

                 Plotters

                   Plotters are just like printers but are much bigger in size. The three main types of
                 plotters include:



                     Drum Plotter:  Uses a  roll  of  paper  and  a  pen  that
                    moves across the surface to create drawings.



                                                                                                Drum Plotter

                                                 Inkjet Plotter: Works like an inkjet printer but is capable
                                               of  printing  larger  formats,  using inkjet  technology  to

                                               produce high-quality images.

                     Flatbed Plotter:  It  has  a  flat  surface  where  the  paper  is
                    placed, allowing for precise printing of larger designs.




                                                       Speakers                                    Flatbed Plotter

                                                       Speakers are  output device that  produce music,

                                                       speech or other sounds, from the computer. They
                                                       convert  electrical  signals into audible sound,
                                                       allowing users to listen to audio content, whether
                               Speakers
                                                       it’s music, movies, or notifications.
                    Recap



                         The computer system is made up of two types of parts—Hardware and Software.
                        A computer works on the IPO (Input-Process-Output) cycle.

                        A computer accepts data and instructions through input devices.
                        Processing is done on the data (Input) entered into the computer, to convert it
                       into meaningful information.
                        The output devices are used to display the information and result of computation.
