5. When a computer has finished processing information, the information needs to be output so that it can be used.
Monitors:
screens or Visual Display Units (VDUs)
display the effects of what the user is doing
can vary in size and resolution.
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.
Sometimes we just need to see the information, on screen or on paper, so we use a monitor or a printer.

6. Speakers:
are used to output sound, whether music or voice
vary a lot in quality.
Headphones:
work in the same way as speakers
can be cordless.
Sometimes we need to hear the information, so we use loudspeakers or headphones.

7. 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.
