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 DEVICES

Printers:• 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








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.








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.






PRINTERS

Inkjet Printer Dot Matrix Printer

Laser Printer Plotter






MONITORS

LCD Screen CRT Monitor

TFT Monitor






Device Benefits

CRT Cheapest monitor to buy; gives a sharp picture

LCD Slim screen; Used for laptops and digital display

TFT Slim screen; quick to refresh because each pixel has its own transistor

Speakers Good for loud music; can address a whole room

Headphones Can listen without disturbing others; good for private conversation

Laser Quick and best quality printer; large paper tray

Inkjet Cheap colour printing; good for printing photos

Dot matrix Impact printer; good for multi-part forms

Plotter Large drawing size; clear lines for technical drawings

Control 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.
