Output devices convey processed data to users. Display devices like LCD and plasma monitors visually output text, graphics, and video. Printers produce hard copies on paper through inkjet, laser, or other methods. Audio output devices like speakers and headphones allow users to hear processed sound files. A variety of other specialized output hardware exists as well, such as data projectors, interactive whiteboards, and fax machines.
