Output Devices

Computer Hardware Components

Output device is a peripheral hardware device in computing.  It is used to communicate the results of processing carried out by a computer by converting the electronically generated information into human-readable form.  More...

Monitor is an output device in computing.  It is the most common output device, which has a visual display, electronic circuitry, and an enclosure.

Today, most of them are TFT (Thin Film Transistor) LCD (Liquid Crystal Display) screens while the older were mostly bulky CRT (Cathode Ray Tube) screens.  More...

Projector is an output device in computing.  It is an optical device that projects images onto a surface such as a projection screen.

Most projectors create an image by shining a light through a small transparent lens, but some newer types of projectors can project the image directly using lasers.  More...

Speaker is an output device in computing.  It is used to output sounds generated by the computer such as signals, songs or movies played.

Computers have their own built-in speakers on the monitors or keyboards.  For better quality, external speakers can be connected using an audio connector or USB (Universal Serial Bus) port.  More...

Headphone is an output device in computing.  It is a pair of small speakers that are held in place close to user's ears.

It converts electrical signals to corresponding sounds which are heard by the user through speakers.  Some are packaged with microphones so that they can be used as input/output devices and can be connected using a phone jack.  More...

Printer is an output device in computing.  It produces human readable representation of text and graphics on paper or similar media.

They are impact printers such as daisy-wheel, dot-matrix, line or non-impact printers such as laser, ink-jet, and now 3D printing.  More...

Plotter is an output device in computing.  It is a computer printer used for high quality output of vector graphics.

They are popular in printing engineering and architectural drawings and designs, which requires high quality and accuracy.  There are different types of plotters such as pen-plotters, electrostatic-plotters, cutting-plotters, etc.  More...

Braille Embossers
Braille Embosser is an output device in computing.  It is an impact printer that renders text as tactile braille cells.

Using braille translation software, a document can be embossed with relative ease, making braille production efficient and cost-effective.  More...
