Equipment connected to a computer that is used to transfer data out of the computer, either to a human user (e.g. as images on a monitor or sound from a loudspeaker) or to some form of permanent record (e.g. printed text). Most output devices are electronic with electromechanical components (e.g. a printer or loudspeaker) and/or electro-optical (e.g. a display screen).Storage devices such as disk drives and magnetic tape drives act as both input devices and output devices (they are "read-write" devices), others such as some CD-ROMs may be input only ("read-only").
