Output Device

Output device data can appear in various forms such as graphics, laser light, sound, or text. Examples of output devices are monitors wich display data or information onscreen, printers wich create hard copy data, and speakers, which produce sound with data.

Examples of output devices follow.

Printers: 

Printers create images on paper, plastic, cloth, and other print media using technologies like ink transfer, heat transfer, chemical reactions, and physical force. Computer output tells printers what images, text, or designs to print.

Monitors:

A computer monitor is an output device that converts electronic signals into onscreen graphics, text, and images. Monitors are important because they give users a visual presentation of keyboard commands and mouse movements. Monitors, also called displays, are standard equipment with most computers and rely on   

varying types of technology. Monitors display output data and show users the end results of the processes taking place inside a computer.

Other Output Devices

A number of the other output devices serve many different functions. All output devices rely on the computer's output data. For example, computer speakers convert output data into sound. CD burners duplicate output data, permanently burning the data into compact discs. Digital projectors display output data as enlarged images for specialized viewing purposes.
