The differences in functionality between the main varieties of printer. Outputs that are audible or take the form of signals which control devices. This lesson will cover:

3 © Boardworks Ltd 2010 3 of 11 Output devices Output devices allow us to harness the processing power of computers to produce the products we require. Can you think of any output devices that have an impact on your daily life?

4 © Boardworks Ltd 2010 4 of 11 When a computer has finished processing information, the information needs to be output so that it can be used. Monitors: are screens or Visual Display Units (VDUs) display the effects of what the user is doing can vary in size and resolution. Sometimes we just need to see the information on screen or on paper. We can use a monitor or a printer. 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. Output devices

7 © Boardworks Ltd 2010 7 of 11 Plotters Traditional plotters work by moving pens over the surface of a page. They were originally used for printing technical drawings made up of lines. Modern plotters tend to be big inkjet printers that can print up to A0 in size. They are expensive to buy and run, and they tend to be used by architects, design firms and engineers. This small plotter is fitted with a blade rather than a pen. It can cut letters and nets for 3D shapes like boxes. It is used mostly for craft purposes. Plotters

Look at the following video. What uses for 3D printers are there in modern business? 3D printers are quite expensive, but if they become cheaper they could become a common place household item. What uses could 3D printers have in the home? Video courtesy of Boxford Ltd

Sometimes we need to hear information, so we use audible output devices. Headphones: work in the same way as speakers can be cordless are used for personal listening. Audible output – sound

10 © Boardworks Ltd 2010 10 of 11 Sometimes we want to control something, so we send a signal to a motor or to a switch that is part of another device, like a robotic arm or a computerized sewing machine. Can you think of any other output devices in your home and school that are controlled by sending electronic signals? Signal output – control
