- LCD
- LCD stands for Liquid Crystal Display. They contain two layers of
polarized glass through which the liquid crystals both block and pass light.
- They can easily be
wall mounted.
- PROS
- They have a low power consumption.
- The heat release is very low.
- Brightness may make
it not suitable in certain uses.
- CONS
- It has static resolution
- Accuracy of colour is not the best
- They can easily be
wall mounted.

- CRT
- CRT stands for Cathode Ray Tubes. This method fires electrons at a
screen to make each pixel glow in the correct colour.
- CRT
runs the highest pixel resolutions generally available.
- PROS
- CRT displays are less expensive than other similar displays.
- CRT displays have fast response times so they’re useful for gamers.
- They’re not as bright as LCD
displays.
- CONS
- They’re not as sharp and produce more of softer images compared to LCD.
- They consume a lot of energy and produce a lot of heat.

- Pixilation is caused
by the over sizing of images which cause them to blur and become pixilated.
- Lumens measure how much light you are getting from a bulb. More lumens means it's a brighter light; fewer lumens means it's a dimmer light.
- OLED has self-illuminating pixels where as an LED screen uses LEDs to light the LCD screen. LED screens are a lot cheaper than OLED due to the technology used and the picture resolution it can produce.
- Printers
- A monochrome printer is a laser printer that only prints black however it is generally faster and produces higher-quality printouts than an inkjet printer.
- A multi functional printer may include a built-in scanner and so can be used as a simple photocopier, suitable for home or small office use.
- Dot matrix printers are used for receipt printing. As they require little amounts of ink and are small.
- Plotters are a specialist type of printer which is able to draw high quality images on very large pieces of paper.
- A thermal printer is a printer in which fine heated pins form characters on heat-sensitive paper.
