Human life is now so engrossed into the different devices that we almost forget to notice what is output device!
In this article, we would learn about the types of output devices, their uses, and many more things.
Keep reading, keep learning!
What is Output Device?
An output device in a computer system is an important component that converts the processed data from the computer into a form understandable and consumable by humans.
These devices take information generated by the computer and represent it in several ways; for instance, on screen, through speakers, or even printed materials.
Users would not be able to perceive their inputs, or the calculations done by the computer without output devices.
Different Kinds of Output Devices
Different Kinds of Output Devices
Output devices vary in how they provide information. There are four main kinds:
1. Visual Output Devices
Visual output devices, also called display output devices, present information graphically. This means users can view their outcomes of their computations.
- Monitors: The most frequently used output device, monitors are used to project text, images, and videos. There are several kinds of monitors: LCD, LED, and OLED.
- Projectors: These devices display computer images onto a big screen or on a wall, so these are often used for presentations.
- Screens: In mobile phones and tablets, screens display information in a compact way.
2. Print Output Devices
Print output devices create hard copies of digital documents.
- Printers: Printers transform digital documents into a physical paper copy. They can be mainly divided into:
- Inkjet Printers: They use liquid ink to print images on paper.
- Laser Printers: High-quality prints are made by using toner and heat to produce prints quickly.
- Dot Matrix Printers: A print head strikes an ink ribbon against paper for printing.
3. Audi Output Devices
These devices convert digital signals into sound.
- Speakers: Speakers take audio signals from the computer and make audible output of music, alerts, and other sounds that the user may use.
- Headphones: It is similar to speakers but for personal use. The device provides direct audio output into the user’s ears.
4. Other Specialized Output Devices
These are devices that perform special functions.
- Plotters: For printing large-scale graphics, such as architectural blueprints.
- Braille Embossers: It converts text into Braille form for the visually impaired users.
- 3D Printers: Build physical objects from digital models by printing layers of materials.
Uses of Output Devices
Uses of Output Devices
Output devices are used in many fields and applications:
- Education: Monitors, projectors are used in class for teaching purposes to show education materials to students.
- Business: Printers are used in businesses in order to print reports, contracts, and marketing material. Projectors are used during meetings to deliver presentations.
- Entertainment: Speakers and monitors make viewing films or playing video games more enjoyable by offering great audio and video.
- Healthcare: Doctors rely on monitors to show patient information and results of imaging tests. Printers are used in writing medical records and prescriptions.
- Design and Engineering: Plotters and 3D printers play a critical role in the development of prototypes and accurate designs in engineering and architecture.
How Output Devices Work
Output devices work by receiving signals from the computer’s processing unit. For instance:
- When a user enters data from an input device such as a keyboard, the computer processes that information.
- The processed information is then transmitted as a signal to an output device such as a monitor.
- The output device reads this signal and turns it into a human-readable format—displays text or images on the screen or audible sounds from speakers.
This process enables users to find or hear the results of their interactions with the computer effectively.
Wireless Output Devices
Wireless output devices are now gaining popularity since they are more convenient to use and flexible. They connect into the computer via Bluetooth or Wi-Fi instead of using traditional wired connections.
Examples include wireless speakers that play audio without needing to be physically connected to the computer and wireless printers through which printout documents can be accessed from any place within range without the need for direct cable connections.
Output Devices vs. Input Devices
Output Devices vs. Input Devices
The ability to understand the difference between output devices and input devices is crucial in understanding how computers work:
- Input Devices: These provide the means by which data are entered into the computer (keyboards, mice, etc.). They translate user instructions into machine-understandable languages that it can process.
- Output Devices: Conversely, these reflect the processed data back to the user, and examples are monitors or printers. They translate machine-generated information into information that humans understand.
While input devices are useful to communicate with the computer, providing commands and data, output devices complete this cycle by displaying the results back to the user.
Advantages and Disadvantages of Output Devices
Though output devices are an important part of computers and help in effective operation, output devices have their own set of advantages and disadvantages.
Advantages:
- User Interaction: Output devices help users interact with the computer by providing feedback on inputs.
- Information Availability: They make information available in various formats (visual, audio, printed), fulfilling the different needs of users.
- Enhanced Productivity: Output devices increase efficiency at workplaces by enabling the communication of results; for example, they can print reports.
- Entertainment Value: Output devices greatly enhance entertainment value by yielding sophisticated sounds and images through audio and visual outputting.
Disadvantages:
- Cost: Some output devices are quite expensive to acquire and maintain for example high-end printers or projectors.
- Space Requirements: Many output devices require significant physical space (e.g., large monitors or printers), which can be a limitation in small environments.
- Environmental Impact: Certain output devices, especially printers that use ink or toner cartridges, can contribute to waste if not managed properly.
- Technical Issues: Output devices can face malfunctions or compatibility issues with software updates or hardware changes.
Conclusion
Output devices are inseparable components of computers which allow effective communication between the users and the machines through the presentation of processed information in viable formats. They include visual displays, such as monitors, audio systems, such as speakers, and more. As such, they serve a wide variety of applications across different industries.
It is important to know what each of them does, their applications, advantages, disadvantages, and how they work for gaining maximum productivity in both personal and professional settings.
