Monitor Monitors allow the user to see the results of the computer processing their information. Monitors come in different sizes and resolutions. Monitors are categorized by their ability to project an image and the size of their screen. The majority of monitors produced for PC computers are VGA (Video Graphics Array) 640 by 480 resolution or SVGA (Super Video Graphics Array) resolution upwards to 1024 by 1024. Macintosh computers are RGB (Red Green Blue) displays with resolution of 640 by 480 to 1024 by 768. The average monitor is 14 inches and has a resolution of 640 by 480. Monochrome (single color ) displays are popular with laptop buyers because they are cheaper to produce (cost less) and the single color doesn't drain the laptop's battery as fast.
Printer Printers give the computer user a "hard copy" of the results of the computer processing the input. This hard copy is usually paper but can be in overhead transparencies or wax thermal paper. Printers are classified by the method they use to produce an image on paper. Printer resolutions range from low resolution of 100 dpi (dots per inch) to high resolution of 600 dpi. Dot matrix printers and ink jet printers are popular because of their low cost ($100 - $300 for B&W) and the high quality of the outpu t . Laser printers are popular with businesses and schools because of the high quality output and moderate price ($500-$1500).
