Output devices convey information from a computer to users. There are four main types of output: text, graphics, audio, and video. Display devices visually output information through flat panel displays like LCD and plasma monitors, or CRT monitors. Audio output occurs through speakers, headphones, or earbuds. Printers output text and graphics onto paper through various technologies like inkjet, laser, or thermal printing. Other output devices include data projectors, interactive whiteboards, and game controllers.
