- 1CRT monitorCRT monitors are based on cathode ray tubes that fire electrons at a screen to make each pixel glow in the correct colour. Ctr monitors are deep due to the length of the cathode ray tube, they also take up a lot of space. They give clear sharp displays at a cheaper price.
- 2TFT monitor (Thin film transistor)TFT monitors are much flatter than CRT. They use liquid crystals to form the image. The image on them many not be as clear as on a CRT monitor.
- 3Inkjet printersPopular for home use as they tend to be cheaper to buy than lasers, tho they can be more expensive to run and are generally slow.
- 4Laser printersThe image is formed using a laser beam on a light-sensitive drum that uses electronic charges to attract toner particles. The page then passes over a heated fuse unit to melt the toner on to the page. Monochrome lasers are popular in offices.
