**Monitors** They are screens that allow you to be able to read the functioning of the computer, they allow you to see the images that you took through a camera, able for you to operate the computer... This is a key part of the computer because if you don’t have the screen you would have no idea what the computer is doing.

There are different types of screens, some are sharper, some are less sharp. This is due to their pixels. Each pixel have 3 different bars, the three major colors and the computer will process and would light up with different strength of light of each bar allowing us to see all colors. They are very small so you wouldn’t be able to normally see them. The resolution such as 1024 X 768 means that there are 1024 pixels across and 768 down meaning there is a total of 786432 pixels on the screen.

There are different types of monitors, such as CRT (Cathode ray tube) monitors, they are rather bulky. Monitors now are LCD (liquid crystal display) that allows the monitors to be flatter and thinner. It also consumes less energy.

Touch screens is another type of monitor, except this time there is an input device built on top of it allowing the user to touch the screen and input data.

**Printer** Printer is another basic output device, they allow people to print images that are captured, made, edited through computer. Printing usually printed as A4 but most computers can print in different sizes. Some printers can also be continuos and print multi amount of pictures. There are different types of Printers too:
 * 1) Inkjet printers - Using tiny sprays of ink on a piece of paper forming shapes and characters that were on the screen. These printers are naturally quiet and can produce very high quality images. But they are very slow as they have to print those tiny dots one by one.


 * 1) Laser Printer- as you know from the name, it is naturally fast printing. It sprays patterns in ink on a drum and then the drum would transfer the image to the paper then heating it so that the ink stays on the paper. This is a very expensive printer and normally black and white because colored would be very complicated and much more expensive.


 * 1) Thermal printers - these printers need special paper, they use heated wires to make dots on a surface of a heat-sensitive paper.


 * 1) Thermal dye transfer printers - this type of printer needs to heat up special dye into gas and process them through a special paper to print out the images. Very expensive though very accurate.


 * 1) Thermal wax transfer printers - this type of printer uses molten wax forming tiny dots of different colors on the paper and they would mix together to make different colors on the paper.
