Explore What Are Output Devices with Real Examples
Published: 25 Oct 2025
When you watch a movie on your computer or print your homework, you’re actually using an output device. These amazing tools help us enjoy what the computer has done after processing our commands.
Output devices are parts of a computer that show, print, or share the results after the computer finishes working with the data. They turn digital information into something we can see, hear, or touch.
In this article, we’ll learn everything about what are output devices, how they work, the different types of output devices of computers, their examples, uses, and some common FAQs.
🖥️ What Is an Output Device?
An output device is a hardware component that shows or presents information from a computer to the user. It takes the data processed by the computer and turns it into a form that humans can understand, like text, sound, or images.
In simple words, an output device helps us see, hear, or feel the results of what the computer has done. It’s how the computer “talks back” to us after we give it commands.
Example:
When you type something and it appears on the monitor, or when you print your notes on paper using a printer, that’s output in action. These are perfect examples of output devices in computer systems that we use every day.
⚙️How Do Output Devices Work?
Output devices operate through a straightforward and clear process that consists of three main steps. Output devices make computer work meaningful and useful by sharing results with us in a human-understandable way.
Let’s understand it easily:
- User gives input → You press a key, click a button, or give a command to the computer.
- CPU processes data → The computer’s brain (CPU) works on that command and prepares the result.
- Output device displays or delivers the result → Finally, an output device shows, prints, or plays the result so you can see, hear, or use it.
For example, when you play music on your computer:
- You click the Play button (that’s the input).
- The computer processes the music file (that’s the CPU’s work).
- The sound comes from the speakers (that’s the output).
🧩 Types of Output Devices
Output devices are divided into different types based on how they present information to the user. Some show visuals, some produce sounds, some print results, and some even let users feel through touch.
Let’s understand these types one by one.
| Category | Description | Examples |
| Visual Output Devices | These devices show information on a screen or display. They help users see text, pictures, and videos. | Monitor, Projector |
| Audio Output Devices | These devices produce sound so we can listen to music, alerts, or spoken words from the computer. | Speakers, Headphones |

| Tactile Output Devices | These devices provide touch-based feedback, mainly used by visually impaired users to feel text or images. | Braille Display |
Each type of output device plays a special role in helping users experience computer results in different ways, by seeing, hearing, printing, or touching.
🖼️ Visual Output Devices
Visual output devices show information on a screen or surface that we can see. They display images, text, and videos so users can view the computer’s results clearly.
Two of the most common visual devices are the monitor and the projector.
Monitor
A monitor is the most common and important output device of a computer. It shows text, images, and videos that the CPU processes. Monitors are used in almost every computer system, from desktops to laptops.
There are different types of monitors, such as CRT (Cathode Ray Tube), LCD (Liquid Crystal Display), LED (Light Emitting Diode), and OLED (Organic Light Emitting Diode).
Example:
The screen on your laptop or desktop computer is a monitor.
Projector
A projector is another type of visual output device that displays computer output on a large screen. It is commonly used in classrooms, meetings, and cinemas where many people need to see the same information or video at once.
Projectors take the image from a computer and project it onto a wall or screen using light.
| Feature | Monitor | Projector |
| Display Size | Small | Large |
| Usage | Personal | Group viewing |
| Output Type | Visual | Visual |
| Portability | Low | Medium |
| Example | PC Screen | Classroom Display |
Both monitor output devices and projector output devices help users view visual information, but they differ in size, usage, and how they display images.
🔊 Audio Output Devices
Audio output devices are hardware components that produce sound. They convert the computer’s digital signals into sound waves that we can hear. These devices let us enjoy music, watch videos, play games, and listen to notifications or alerts.
The two most common audio devices are speakers and headphones.
Speakers
Speakers are popular audio output devices that turn digital signals from the computer into sound waves. They allow users to hear music, video sounds, game effects, or system alerts. Speakers can be built into the computer or connected externally for louder and better sound.
Example: The computer speakers you use to listen to songs or movie dialogues.
Headphones / Earphones
Headphones or earphones are audio output devices that allow private listening. They are perfect for situations where you don’t want to disturb others, such as during calls, online classes, or while watching videos in a quiet place.
They come in wired and wireless versions and are widely used with computers, mobile phones, and tablets.
Example: Wired or wireless headphones used during online meetings or while listening to music.
| Device | Purpose | Example |
| Speakers | For loud audio | Computer speakers |
| Headphones | For personal listening | Wired or wireless headphones |
Both speakers and headphones are output devices that help convert computer signals into sound, one for everyone to hear and the other for personal use.
🖨️ Print Output Devices
Print output devices are hardware tools that give us a hard copy of computer data. They take digital information and print it on paper or other materials.
The most common print output devices are printers and plotters.
Printer
A printer is a popular output device that prints digital data onto paper. It allows users to create physical copies of text, images, or documents stored on the computer. Printers are used at home, in offices, and in schools for everyday printing tasks.
Common types of printers include Inkjet, Laser, and Dot Matrix printers.
- Inkjet printers spray tiny ink droplets to create images.
- Laser printers use toner and lasers for fast, clean printing.
- Dot matrix printers use pins and ink ribbons to form letters or graphics.
Example: Printing reports, photos, or homework using a laser printer.
Plotter
A plotter is a special type of printing output device used to produce large and detailed drawings. It is mostly used by architects, engineers, and designers to create blueprints, maps, and technical plans.
Plotters draw lines using pens or cutting tools instead of spraying ink, which makes them ideal for vector graphics and precise line work.
Example: A CAD plotter used by an architect to print building plans.
| Feature | Printer | Plotter |
| Output | Text and images | Graphs and designs |
| Use | Office, schools | Engineering, architecture |
| Printing Type | Raster | Vector |
| Example | Laser printer | CAD plotter |
Both the printer output device and the plotter output device help us get real-world copies of our digital work, but they differ in size, purpose, and printing style.
🧏 Tactile Output Devices
Tactile output devices are special types of output devices designed mainly for people with visual disabilities. These devices help users feel information through touch instead of seeing or hearing it.
One of the most common tactile devices is the Braille Display.
A Braille Display converts text from the computer screen into raised dots that can be read by touch using the Braille system. This allows visually impaired users to read digital content such as emails, documents, or web pages.
Example: A Braille Display connected to a computer that shows letters as raised dots so users can read with their fingers.
These special output devices make computers more inclusive and accessible to everyone, regardless of their visual abilities.
