When 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 Outcomes Good – 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.

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 Lesson Aim To explore Output devices in real life situations. Lesson Outcomes Good – 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.

When 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. Lesson Aim To explore Output devices in real life situations. Lesson Outcomes Good – 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.

When 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.

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. Lesson Aim To explore Output devices in real life situations.
