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.
Lesson Aim• To explore
Output devices in real life situations.
Lesson OutcomesGood – will understand what an output device is and give a real life example.
Great – will be able to explain the 4 types of output. Visual, Printed, Audio & Control.
Fantastic – will be able to recommend and justify specific output solutions for real world problems.

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.
