Q: What are the different types of monitors... explain them
A: LCD/LED - Liquid Crystal Display
     - contains groups of RGB diodes to form each pixel, typically backlit
     - reach maximum brightness almost instantly
     - image is sharper with more vivid colours
     - produce brighter light
     - allow for thin contruction
     - last almost indefinitly
     - consume little power
OLED - Organic LED
     - flexible/bendable as they can be made from plastic
     - much thinner than LCD
     - brighter and need no backlight
     - fast to refresh
     - produce truer colours
     - do not last as long and sensitive to water.

Q: Explain the different types of printers
A: Laser printer - high quality, high speed, use powdered ink called toner
Inkjet - spray minute dots of ink onto paper to create image
Dot matrix - Like a typewriter, slow and noisy, very cheap, can operate in poor conditions
3-D printers - print plastic onto a base to build 3D shape, expensive, used in prototyping.

Q: List some output devices
A: - Monitor (CRT, LCD, OLED)
 - Speaker (Loud, headphone)
 - Printer (Laser, Inkjet, Dotmatrix, 3D)
 - Projector
 - Actuators
