Output devices

MONITOR/SCREEN

Cathode ray tube monitor

LED monitor

A monitor is an output device that displays what you are doing. The first monitors were made using cathode ray tubes, which were huge and required a lot of space. Then computer companies started making them using LED (Light Emitting Diodes); then LCD (Liquid Crystal Display); and then using OLED (Organic Light Emitting Diodes). LED, LCD, and OLED monitors are slim and save lots of space.

PRINTER

Printer

Printers are used to make a printout of what you see on the screen of your desktop. Usually the output of a printer is called “hard copy.” These days, many printers and scanners are embedded into one machine, and printers can produce two types of outputs—i.e., black-and-white and color prints. Some types of printers include laser printers, dot printers, inkjet printers, and daisy-wheel printers.
