OUTPUT DEVICESWhen a computer has finished processing information, the information needs to be

output so that it can be used.

Sometimes we just

need to see the

information, on screen or on paper, so

we use a monitor or

printer.

OUTPUT DEVICESPrinters:

• Produce a paper copy of the user’s

work: a ‘hard copy’• Come in three main

types: laser, inkjet and dot matrix.

Some businesses also use plotters.

Monitors:• Screens

or Visual Display Units

(VDUs)• Display

the effects of what the user is doing

• Can vary in size

and resolution

OUTPUT DEVICESWhen a computer has finished processing information, the information needs to be

output so that it can be used.

Sometimes we need to

hear the information, so we use

loudspeakers or

headphones.

Headphones:• Work in

the same way as

speakers.• Can be

cordless.

Speakers:• Are used

to output sound,

whether music or

voice• Vary a lot

in quality.

OUTPUT DEVICESWhen a computer has finished processing information, the information needs to be

output so that it can be used.

Sometimes we want it to control something, so we send a signal to a motor or a switch

that is part of another device,

like a robotic arm or a computerized sewing machine.

Device BenefitsCRT Cheapest monitor to buy; gives a sharp pictureLCD Slim screen; Used for laptops and digital displayTFT Slim screen; quick to refresh because each pixel

has its own transistorSpeakers Good for loud music; can address a whole roomHeadphones Can listen without disturbing others; good for private

conversationLaser Quick and best quality printer; large paper trayInkjet Cheap colour printing; good for printing photosDot matrix Impact printer; good for multi-part formsPlotter Large drawing size; clear lines for technical

drawingsControl Safe in all conditions; good for repetitive tasks

SUMMARY• There are four kinds of output

devices; devices that produce a visual or printed output, those that produce an audio output and others that use control as output.

• The three main types of monitors at Cathode Ray Tube (CRT), Liquid Crystal Displays (LCD) and Thin Film Transistor (TFT).

• There are three main types of printers: dot matrix, inkjet and laser.

• Sound devices include speakers and headphones.

• Control devices include hydraulics, pneumatics and motors.
