What are Output Devices? Types & Applications of Output Devices

Is output device information what you are looking for? Here you will find information about output devices, including their types and applications. 

We will discuss the different types of output devices and their applications to help you choose the most appropriate one for your application.


The output devices of a computer system allow users to view and interact with the information that the system processes.  

Devices that allow a computer to communicate the results of its processing to a user or another device are known as output devices. 

Each of the three types of output devices has a unique application in various fields, depending on its mode of output. 

To facilitate the communication of information and allow individuals to access and comprehend the processed data, output devices play an essential role.

What are Output Devices?

It is a type of output device that allows a computer to communicate the results of its processing to the user or another device. 

Visual, auditory, and tactile devices are used to present the processed data to the user in a manner that is easy to understand. 

Displays, speakers, printers, and monitors are among the examples of output devices.

Types of Output Devices:

Depending on the mode of output, such as visual, auditory, or tactile, there are various types of output devices available.

Visual Output Devices:

The visual output devices produce a visual representation of the processed data. There are several types of visual output devices, including:


Visual output devices such as monitors are the most commonly used. Users can view and interact with the information displayed on the screen. 

There are two types of monitors: cathode ray tubes (CRTs) and flat-panel displays (FPDs). 

The display of data on a CRT monitor is based on a cathode ray tube, whereas the display of data on an FPD monitor is based on liquid crystals or light-emitting diodes (LEDs).


Typically, printers are output devices that produce hard copies of the processed information. Inkjet printers, laser printers, and thermal printers are among the various types of printers available. 

To produce an output, inkjet printers spray the ink onto the paper using tiny nozzles, while laser printers use a laser beam. A thermal printer produces its output by using heat.


The purpose of a projection device is to display the processed data on a large screen or wall, enabling several people to view the data simultaneously. 

To project the image onto the screen, a light source and a lens system are used.

Auditory Output Devices:

A device that provides an auditory output of processed data is called an auditory output device. There are several types of auditory output devices, including:


The speaker is a device that produces sound, allowing the user to hear the data that is being processed. 

An external hard drive or a built-in hard drive can be used. Connecting external speakers to your computer via a cable or wirelessly is more convenient than using built-in speakers, which are integrated into your computer.

The term headphones refer to a device that produces sound and is worn over the ear. Using them, the user can listen to the processed data privately without disturbing anyone else.

Tactile Output Devices:

It is a form of tactile output when the processed data is presented in a physical form that can be touched. The following are some examples of tactile output devices:

Braille printers: 

There are several types of braille printers, which operate by producing braille, a system of raised dots that can be read by touch. 

Data processed by these devices can be accessed by individuals who are blind or visually impaired.

3D printers: 

The 3D printer is a device that produces physical objects by laying down successive layers of material. Various industries use them to produce prototypes and finished products.

Applications of Output Devices:

Various fields rely on output devices for a variety of purposes. Output devices are used for a variety of purposes, such as:


Educational institutions use output devices to display and print course materials, assignments, and other documents, such as monitors, projectors, and printers.


Providing and printing documents, presentations, and reports requires output devices such as monitors, printers, and projectors.


A monitor or printer is used in healthcare settings to display and print patient information, test results, and other medical records.


For gaming, watching movies, and listening to music, output devices such as monitors, speakers, and displays are used.


Manufacturing uses output devices such as 3D printers and braille printers to create prototypes and finished products, as well as to provide information to people with disabilities.

A computer system’s output devices are essential for displaying and interacting with the data processed by the system. 

Each output device has its application in different fields and is available in visual, auditory, or tactile formats. 

The output devices play a critical role in facilitating the communication of information and providing individuals with the ability to access and interpret the processed information.
