By on 06:10

In my previous post I discuss about computer input devices and now I am discussing "What are computer output devices?Explain its different types with examples". Output devices are those devices which display the required result or in simple words which display the output of the final result.Output devices provide the output of data/information.

Output devices result are of 2 types:-

1)Soft copy output(Which is present in digital form in a computer).

2)Hard copy output(Which are present in paper form).

Examples of some common output devices:-

1)VDU:-It stands for Visual Display Unit.It may be a screen or a monitor.Monitor is like a TV screen(it can be plasma,LED,LCD).Resolution of monitor depends on the number of pixels per inches.

Monitor display text,images,video,audio,files,
document etc. on the screen.




2)Printer:-Printer is an output device which is used to show result in hard copy form or in paper form.




Type of Printer:-

Printer generally divided into two types namely Impact and non-impact printer.

1)Impact Printer:-In these type of printer hammer strikes against the paper through ribbon.Printing quality of impact printer is not good,it create noise while printing example dot matrix,daisy wheel etc.

2)Non-Impact Printer:-In these type of printer hammer doesn't strikes against the paper through ribbon.Printing quality of impact printer is good,it doesn't create noise while printing example laser printer,ink jet printer.

Plotter:-Plotter is a well known output device which produce high quality graphics in multiple colour.Plotter is used to create maps,charts etc. on a paper sheet.




Some other output devices are terminals,
Voice synthesiser,video adaptor,speech synthesizer,projector etc.
