Did you want to learn about Computer output devices? 

Well, you have already landed on the right web page. 

Today in this post I'm going to share with you the topic of what is a computer output device? Some commonly used Computer output devices.

So, Let's see...

What is Computer Output Device?


An output device is a piece of Computer hardware equipment used to communicate the results of data processing carried out by an information processing to the outside world. 

Some Computer Output Devices

  • Monitor
  • Printers
  • Speaker
  • Headphones
  • Projector
These are some commonly used Computer output devices. Below I described all these common Computer output devices.


The monitor is the display where you see the result of a Computer program. A monitor is of two kinds - a monochrome display monitor and a color display monitor. 

A monochrome display monitor uses only one color to display text and a color display monitor can display 256 colors at a time. 

An image on the monitor is created by a configuration of dots, also known as pixels. The refresh rate of a monitor is measured in Hertz (Hz). 


A printer prints information and data from the computer onto paper. It can print documents in color as well as in black and white. The quality of a printer is determined by the clarity of a print. Printer resolution is a numerical measure of print quality that is measured in Dots Per Inch (DPI). 


Speaker is an output device that receives sound in the form of an electric current. Speakers need a sound card that is connected to the CPU, sound card generates sound via a card. 

Computer speakers are the speakers which are attached internally or externally to a computer. 


Headphones are a pair of small loudspeakers, held close to a user's ears and connected to a signal source such as an audio amplifier, radio, CD player, or portable media player. Headphones are also called stereo phones, headsets, or cans. 


It's an output device that is used to project information from a computer onto a large screen so it can be viewed by a large group of people simultaneously. 

Nowadays projectors are widely used for classroom training or conference holes with a large audience. 

There are mainly two types of projectors are used, one is the Liquid Crystel Display (LCD) projector and the other is Digital Light Processing (DLP) projector. 

These are the most commonly used Computer output device.
