What is Output Device?

Definition: Output device is a hardware component that is going to use for displaying the results of processed data.

Output devices allow to convert the electronic information into the humans readable format. This format may be audio, visual, textual, or hard copy such as a printed document.

Key difference in between input device and output device is that input device helps to insert data to computer, but output device retrieve data from computer’s storage memory.

These output devices have two variants like as wired or wireless.

Let’s Get Started!!

How Does Output Device Work?

Output device receives data from a computer and then translate that data into another form, such as audio, visual, textual, or hard copy such as a printed document.

In order to work, an output device needs to receive a signal from the computer. An output device works by receiving a signal from the computer and using that signal to perform a task to display the output.

For example, if you type “H” on a computer keyboard (input device), it sends a signal to the computer. The computer processes the input and once completed, sends a signal to a monitor (output device). The monitor receives the signal and displays the “H” to the screen. If supported, that “H” could also be printed (outputted) to a printer.

Types of Output Devices

Computer output devices have ability of making audible, visible, interpretable or physically accessible result. As depend of these, output devices are classified into four categories like as Visual Output Devices, Data Output Devices, Print Output Devices, and Sound Output Devices; below shown different types of output devices in detail.

Now, getting start to explain in detail about most common used 10 to 12 examples of output device of computer along with their image



The monitor is commonly going to use as output device because it helps to show all result as the e graphical form. User requires serving the power supply to the computer monitor. The monitor is getting to link via VGA cable to CPU (Central Processing Unit). Monitor has two elements like as cathode ray tube and a fluorescent screen.

You can call monitor with another name as the “Video Display Terminal (VDT)” and “Visual Display Unit (VDU)“.

Function of Monitor

  • The monitor contains the various components like as circuitry, screen, and button for getting to adjust settings of screen, power supply, and casing that helps to keep all those components.

Types of Monitor Are:

TFT Monitors: TFT stands for “Thin Film Transistor”, and these transistors are also going to use for making high quality flat panel liquid-crystal displays (LCDs). It allows to display has transistor for every pixel on the screen.

LED Monitors:  LED stands for “Light Emitting Diodes”, and LED monitor is a flat screen flat-panel computer monitor. It can run at the lower temperature as well as consuming less power.

DLP Monitors: DLP stands for “Digital Light Processing”, and it is built with chip that is construct with tiny microscopic mirrors and a spinning color wheel to create an image. It is able to deliver great response time as well as 3D capabilities.

CRT Monitors: CRT stands for “Cathode Ray Tube”, and it is based on the cathode ray tubes. They are similar to vacuum tubes which produce images into form of video signals.

This is an expansion card that is embedded on the motherboard, and it helps to enhance the quality of video and other graphical content. Video card allows to increase the experience of playing game, photo, watching movies, etc.

Now these days, video card is attached by default inside the computer, but if you want to boost up your visual elements then it can be added as externally.

Function of Video Card

The video card processes images and video, enabling visuals to be seen on a display.

Braille Reader


Braille reader is a electronic hardware device that is very helpful for blind people for getting to read texts, which are displayed on the monitor screen.

There are several kinds of Braille reader such as large units of keyboard size for computer system and small units for tablets and laptops.

Function of Braille Reader

Computer system transfers text to the Braille reader, and it translates into Braille format and displayed by raising pins via flat surface. So it is also called the “Braille Display”.

Speech Synthesizer


This is a speech generating device that helps to convert text to speech.

Speech synthesizer speaks out loud the commands, which are inputted by the use in the form of text.

It is very helpful for individuals suffering from speech impairments.



Plotter is also hardware output device that is similar to printer but it allows to print wide format materials such as banners, brochures, pamphlets, etc.

Mostly, plotters are used in the engineering and basically draw a certain image on a number of straight lines.


Touchscreen devices are also called the ‘Input/output device’ because they are able to get input in the form of touch by nature and then process this input by the computer, finally display the output on same screen.

Touchscreens are mostly embedded into several devices cause of its portability. They are thin, lightweight panel designed to get output from a computer system. A touch screen has touch-sensitive or monitor that capable to provide the output as visuals or graphics format.

Touch screens are usually used into many modern devices like as tablets, smartphone, and laptop and so on.

Functions of Output Devices

Output devices assist to perform many mandatory functions for your computer system. These output devices are connected with computer through wired or wireless mode. Output devices grab the signals from computer as input and process this received signals to produce output in many formats.
