 * TASK 1: OUTPUT DEVICES **

Output devices let you see data that has been processed or is stored on the hard disk or any other storage media. A monitor lets you see data on the screen, a printer produces a paper copy that you can hold and read.

Complete the table below:

|| A monitor is the most commonly used output device. It allows you to see the document that you are working on. As you make changes to the document, the monitor automatically updates so that you can see your work. ||  ||    || A device that translates digital data into physical ink that can be read, also known as a hard copy. It is found all over the place and found especially more in offices where heavy high-quality printing is needed || The reason it is called a laser printer is becauses unique way of transferring ink to paper give it the warm touch after printing || || The ink-jet printer is the simplest and oldest variation of the printer. It is better than the laser-printer in that it is smaller and cheaper than the laser printer. || The term Xeroxed was actually from the Xerox paper printer which was the best of the time ||
 * ** Output device ** ||  ** Description **  ||  ** Extra fact you know/ found out **  ||
 * Monitor
 * Laser printer
 * Ink-Jet printer
 * Digital projector

|| The digital printer uses a high powered bright light to project the images from the computer to a screen. It is good in the way that it is smaller and more convenient than a tv but can not be seen in bright light || 1080p projectors do actually exist || || Plotters as the names imply plot information given to them, a plotter could plot when seismic tremors occur ore such. Plotters can be seen in research labs or such facilities. || The barometer is also a form of plotter ||
 * Plotter
 * Speakers

|| Speakers use magnets and vibrating components to create acoustical sound, the quality of the sound depends on the quality of the EQ and as with all ICT devices, Bad music in, Bad music out || Speakers use Neodynium magnets to produce sounds. || || Headphones are smaller more portable variations of speakers that also have a headband to keep them in place. || The original headphones were mono, then stereo, then surround, then 23.1 Ultimate 360 surround sound || || Led light stands for light emitting diode, these are more efficient than the modern lightbulb and create a brighter light. LED lights can also come in several colors. || LED light diodes used to look like little Z shaped lumps ||

 * LED Lights




 * TASK 2: FILL IN THE BLANKS **

Copy the sentences below and complete the blanks using words from the list. You should use each word only **__once__**.
 * ** LAPTOP ** ||  ** PIXELS **  ||  ** SIZES **  ||  ** SCREEN **  ||
 * ** INCH ** ||  ** OUTPUT **  ||  ** DOTS **  ||  ** EXPENSIVE **  ||

Monitors
These are the most common _Output__device. Sometimes they are called a __screen_ instead. All desktop computers have a separate monitor, but a ___laptop__ computer will have a monitor which is attached by hinges. Monitors come in different ____sizes_ but the larger they are, the more __expensive___ they tend to be. The picture on a monitor is made up of thousands of tiny coloured _dots_ called ___pixels__The quality of a monitor depends on the number of pixels per __inch__.

Printers

 * ** CARTRIDGES ** ||  ** INK-JET **  ||  ** CARBON **  ||  ** HARD **  ||
 * ** LASER ** ||  ** RIBBON **  ||  ** TONER **  ||   ||

Printers are useful for creating a __hard__copy of your work. There are two main types of printer:
 * Laser printer
 * Ink-jet printer
 * ____laser___ printers ** work much like a photocopier, powdered ink is fused onto paper by heat and pressure. They produce a very high quality output, are quiet and fast, although quite expensive to buy. They use ___toner____rather than cartridges.
 * _ink jet_ printers ** are cheaper to buy, offering black and white or colour printing with reduced levels of quality and speed. The nozzles fire a jet of liquid ink through tiny holes, hence the name, ‘ink-jet’. The ink is stored in___cartridges_.


 * TASK 3: CHOOSE THE MOST SUITABLE OUTPUT DEVICE **

Which output device would you recommend for the following tasks:


 * To produce a large number of letters in high quality || Laser printer ||
 * Producing very large sheets such as blueprints || Laser printer ||
 * Producing a small number of coloured leaflets || Laser printer ||
 * Looking at changes that you are making to the document you have open || Monitor ||
 * Display a presentation to an audience || Projector ||
 * Listen to music with friends || Speakers ||
