Printer: A printer is an output device that produces a physical copy of digital documents on
                    paper. Printers are classified into two types: impact and non-impact. Impact printers create
                    images on paper by striking it with a metal pen, while non-impact printers use methods like
                    spraying ink. Common printers include:
                    •   Dot Matrix Printer: This type of impact printer functions similarly

                        to a typewriter. The printer head strikes the paper through an ink
                        ribbon to print characters.



                                          •   Inkjet Printer: Inkjet printers are non-impact printers that produce
                                             prints by spraying ink onto paper line by line. They are faster than dot
                                             matrix printers but are more expensive and consume more ink. Inkjet
                                             printers use ink cartridges.


                    •  Laser Printer: Laser printers, another type of non-impact printer,

                        use a laser beam to transfer  toner  onto paper. They offer faster
                        printing  speeds and  superior  print  quality compared  to inkjet
                        printers. However, they are more costly and are typically used where

                        high-quality printing is essential.
                    Plotters: A plotter is a specialised output device designed to produce high-quality, detailed

                    graphics  and  large-scale  documents.  Unlike printers  that  use ink or  toner,  plotters  draw
                    continuous lines with pens, making them ideal for precise technical drawings, architectural
                    plans, and large-format prints. There are two main types of plotters: drum plotters, which
                    rotate the paper, and flatbed plotters, which keep the paper flat while drawing. Plotters are
                    often used in architecture, engineering and design. They are great for making detailed plans
                    for things like buildings and maps.























                    Speakers: The speakers are output devices that produce sound
                    from a computer, including music, speech, and other audio. They
                    are commonly used for listening to music, watching movies, and
                    other audio-related activities.
