Definition and function of Computer Output devices
1- LCD projection panels
A projection panel (also known as a ceiling screen or LCD panel) is a device that, although no longer in production, was used as a data projector is today. It works with an overhead projector. The panel consists of a translucent LCD screen and a fan to keep it cool.
2- Monitor (LED, LCD, CRT, etc.)
The display device in modern monitors is usually a thin film transistor liquid crystal display (TFT-LCD) with LED back light which has replaced the back light with cold cathode fluorescent lamp (CCFL). Previous monitors used a cathode ray tube (CRT) and some plasma displays (also called gas-plasma).
3- Printers (all types)
A printer is a hardware output device used to generate a hard copy and print any document. A document can be of any type, such as a text file, an image, or a combination of both. … 2D printers are used to print text and graphics on paper, and 3D printers are used to create three-dimensional physical objects.
Types of printers
Solid ink printers.
Professional inkjet printers.
Home inkjet printers.
Multi function printers.
A plotter is a printer that interprets commands from a computer to make line drawings on paper with one or more automated pens. … Plotters were the first type of printer capable of printing with color and rendering graphics and full-size technical drawings. Typically, plotters are much more expensive than printers.
A projector or image projector is an optical device that projects an image onto a surface, typically a projection screen. Most projectors create an image by projecting light through a small transparent lens, but some newer types of projectors can project the image directly, using lasers.
Headphones are a pair of small speakers worn on or around the head above a user’s ears. These are electroacoustic transducers, which convert an electrical signal into a corresponding sound.
7-Computer output microfilm (COM)
Computer-Output-on-microfilm (COM) (also computer output microfilm) is. a process for copying data from a storage medium on a computer to microfilm. COM can be produced as microfiche or 16mm roll microfilm. a technology that allows the output of computers to be recorded directly on microfilm rather than on paper.
Loudspeaker is defined as an electrical device used to increase the volume of sound or music. An example of a loudspeaker is the way music is listened to in a car. … The definition of a speaker is a spokesperson or a person giving a speech. An example of a speaker is the person around whom people have gathered to hear about something.
9-Visual display unit
An electronic visual display, informally a screen, is a display device for the presentation of images, text or video transmitted electronically, without producing a permanent record. Electronic visual displays include televisions, computer monitors, and digital signage.
A film recorder is a graphics output device for transferring images to photographic film from a digital source.
Devices which are Input and output at the same time
- Network cards
- Audio cards / Sound card
- Headsets (the headset consists of speakers and a microphone.
- The speaker acts as an output device and the microphone acts as an input device
- Fax (FAX) (it has a scanner to scan the document and also a printer to print the document)
