The display device in modern monitors is typically a thin film transistor liquid crystal display (TFT-LCD) thin panel, while older monitors used a cathode ray tube (CRT) about as deep as the screen size. The Organic light-emitting diode (OLED) monitors provide higher contrast and better viewing angles than LCDs but they require more power when displaying documents with white or bright backgrounds.
Projector
It is a device used to project an image on the flat surface like computer screen. It is mainly used in presentations, seminars, and meetings. They are also used in schools. Home theater enthusiasts also use them as a good projector will display an image that looks better and more accurately represents the source material than most TVs on the market ever would.
Printer

Dot-matrix printers are now almost extinct. They used a ribbon and made a lot of noise.
Daisy Wheel printers are a typewriter printer; Results look hand-typed with excellent looking text, no real graphics and very loud.
Laser printers transfer tiny particles of toner onto the paper.
Speaker
Speaker is a hardware device that is connected to a computer’s sound card. The sound card outputs the sound generated by the computer.
Video Card
The video card is an expansion card that allows the computer to send graphical information to a video display device such as a monitor, TV, or projector. It is also known as Graphics Card, Video Board, or Video Controller or Video adapter.
Plotter

FAQs on Output Devices or Output Units - Computer Hardware, Computer Awareness - Famous Books for UPSC Exam (Summary & Tests)
| 1. What are output devices in computer hardware? |  |
Ans. Output devices in computer hardware are peripheral devices that provide information or results from the computer to the user. These devices take the electronic data processed by the computer and convert it into a human-readable form. Examples of output devices include monitors, printers, speakers, and headphones.
| 2. How do output devices function in a computer system? | |
Ans. Output devices function by receiving electronic signals or data from the computer and converting them into a form that can be perceived by humans. For example, a monitor receives digital signals from the computer's graphics card and displays them as visual output on the screen. Similarly, a printer receives data from the computer and produces printed copies of documents or images.
| 3. What is the importance of output devices in computer systems? | |
Ans. Output devices play a crucial role in computer systems as they enable users to receive and interact with the information processed by the computer. Without output devices, the computer's output would remain inaccessible to humans. These devices facilitate communication, provide visual or auditory feedback, and allow users to view, hear, or print the results of their input or processing activities.
| 4. Can output devices be used for input purposes as well? | |
Ans. While output devices are primarily designed to provide output to the user, some devices can also serve as input devices to a certain extent. For example, a touchscreen monitor can not only display information but also allow users to interact with the computer by touching the screen. Similarly, some printers have built-in scanners that enable them to scan documents and convert them into digital format, thereby performing an input function as well.
| 5. What are some common examples of output devices? | |
Ans. Some common examples of output devices include:
- Monitors: These display visual output by presenting images and text on a screen.
- Printers: They produce hard copies of documents, images, or other digital content.
- Speakers and headphones: These output devices produce sound or audio output for listening purposes.
- Projectors: They display visual output on a larger screen or surface, such as a wall or projector screen.
- Plotters: These devices are used to draw or print large-scale graphics, diagrams, or blueprints.
