Output devices
Out put devices are used to display results of processing to the user. They perform the following functions:
Examples include: Monitor, printer, plotter, speaker, and multimedia projector.
1. Monitor
Monitor is the most commonly used output device used to display results of processing. It has a TV like shape. Pictures on monitor are formed with picture elements called PIXEL. Monitors may be Monochrome that will display results in Black & White. Color Monitors are also available. They display results in multi colors. Monitor produces soft copy output.
2. Printers
Printers are used to produce hard copy out put. They print processing results on paper. Printers are divided into two main categories:
· Impact Printers
· Non Impact printers
Impact Printers.
These printers print with striking of hammers or pins on ribbon. For example Dot Matrix printer and daisy wheel printers are impact printers.
Non-Impact Printers.
These printers do not use striking mechanism for printing. They use electrostatic and laser technology. Quality and speed of these printers is better than Impact printers. For example Laser printer and Inkjet printers are non-impact printers.
3. Speaker
Speaker produces sound output. We can listen recorded voices, sounds or music with the help of speaker. Speaker produces sound output with the help of sound card.
4. Plotter
Plotters are used to draw different designs of buildings or internal structure of machines. Mostly Engineers and Architects use plotters.
5. Multimedia Projector.
Multimedia projector is used to produce computer output on a big screen. These are used in meeting rooms or in classrooms of educational institutes.

Out put devices are used to display results of processing to the user. They perform the following functions:
- Receive results from memory
- Convert data into human readable form
- Display results to the user
Examples include: Monitor, printer, plotter, speaker, and multimedia projector.
