Output devices are the components of a computer system that are used to display or print the results of the computer’s processing. Output devices can range from the simple, such as a monitor or printer, to the more complex, such as a projector or interactive whiteboard.
The most popular output device is the monitor. Monitors come in a variety of styles, including Cathode Ray Tube (CRT), Liquid Crystal Display (LCD), Light Emitting Diode (LED), and Plasma. CRT monitors are the oldest type of monitor, and are generally bulkier and heavier than the newer LCD, LED, and Plasma monitors. LCD monitors are the most common type of monitor, and are thinner and lighter than CRT monitors. LED monitors are similar to LCD monitors, but are more energy efficient and have a longer lifespan. Plasma monitors are the most expensive type of monitor, but they offer the best picture quality.
Printers are another popular output device. Printers come in two main types: impact and non-impact. Impact printers use a hammering action to print characters onto paper. Examples of impact printers include dot matrix, daisy wheel, line, drum, and chain printers. Non-impact printers use laser or inkjet technology to print characters onto paper. Laser printers are more expensive than inkjet printers, but they offer higher quality prints and are faster.
Projectors are also a popular output device. Projectors are used to display images onto a wall or screen. They are often used in classrooms, offices, and other public spaces to display presentations or videos. Projectors come in a variety of styles, including LCD, DLP, and LED.
In addition to the popular output devices mentioned above, there are also other output devices such as interactive whiteboards, speakers, and headphones.
Output devices are an essential part of any computer system, and are used to display or print the results of the computer’s processing. Monitors, printers, and projectors are the most popular output devices, but there are also other output devices such as interactive whiteboards, speakers, and headphones.
