What Is An Output Device? Definition, and Examples - VS COMPUTER CLASSES

 

What Is an Output Device?

An output device is a piece of computer hardware that receives data from a computer and then translates that data into another form. That form may be audio, visual, textual, or hard copy such as a printed document.

The key distinction between an input device and an output device is that an input device sends data to the computer, whereas an output device receives data from the computer.

For example, using a microphone to record a podcast is an example of using an input device. Listening to the recorded podcast through a connected speaker is an example of using an output device. Both output and input devices are examples of auxiliary, or peripheral, devices.

There are four different categories of output device:

• visual
• data
• print
• sound

Visual Output Devices

When output devices let uses to view the result or output as image or video format on the screen, then these output devices are known as ‘Visual Output Devices’. For examples are video card, projector, monitor and so on.

Data Output Devices

As the name suggests, when user are capable to read and understand. But it can’t get to access otherwise. These types of result are usually produced in textual format. For example – GPS and more.

Print Output Devices

These types of output devices let you to produce a printed hard copy of electronic data processed by computer system are known as print output devices. For example are plotter, printer, braille reader, and more.

Sound Output Devices

These kinds of output devices receive the information from the computer in audio formats is known as sound output devices. For examples are sound card, headphones, speakers, etc.

Examples of Output Devices

1. Monitor
2. Printer
3. headphones
4. Speakers
5. Projector
6. GPS
7. Sound card
8. Video Card
9. Plotter

1. Monitor

Mode: Visual

Function: A monitor consists of a screen, circuitry, a power supply, buttons to adjust screen settings, and a casing that contains all of these components. A monitor displays data from a computer onto a screen so the user can interact with the data via a digital interface.

Monitor is also called as the “Video Display Terminal (VDT)” and “Visual Display Unit (VDU)“.

Types of Monitor Are:

TFT Monitors: TFT stands for “Thin Film Transistor”, and these transistors are used 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.

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.

LCD Monitors: LCD stands for “Liquid Crystal Display”, and it is worked as the technology of liquid crystal display that is getting light weight than CRT monitor.

Plasma Screen Monitors: Plasma monitor also like as a flat panel display, and it totally based on the plasma display technology.

OLED Monitors: OLED stands for “Organic Light Emitting Diode”, and they are flat displays which are made with pixels from OLEDs rather than liquid crystal filled units.

2. Printer

Mode: Print

Function: The function of a printer is to create a copy of whatever is sent from the computer to the printer. Printers take electronic data sent from a computer and generate a hard copy.

Printers are divided into two categories, like as

• Impact Printers
  • Character Printer
  • Line Printer
• Non Impact Printers
  • Laser Printers
  • Inkjet Printers

3. Headphones

Mode: Sound

Function: Headphones output audio from a computer through two individual headphones for a single listener. Also known as earphones, headphones allow you to listen to audio without disrupting other people in the vicinity.

Types of Headphones

• Over-Ear Headphones
• In-Ear Headphones
• Ear buds
• Bluetooth Headphones
• Noise-Cancelling Headphones
• Closed-Back Headphones
• Open-Back Headphones
• On-Ear Headphones

4. Computer Speakers

Mode: Sound

Function: Computer speakers are hardware devices that transform the signal from the computer's sound card into audio. Speakers create sound using internal amplifiers that vibrate at different frequencies according to data from the computer. This produces sound.

Function of Speakers

The primary function of speaker is to transform the signals from the sound card of computer into audio. Computer speakers produce the sound with using of internal amplifiers which allow to vibrate at various frequencies according to data from the computer.

5. Projector

Mode: Visual

Function: As its name suggests, this output device "projects" computer images or video onto a wall or screen.

Types of Projectors

DLP Projector: DLP stands for “Digital Light Processing”, and it is getting more popularity because it is lightweight, as well as produces the crisp output.

LCD Projector: LCD stands for “Digital Light Processing”, and it is able to produce the ultra quality video output, so it is mostly used in the theaters.

CRT Projector: CRT stands for “Cathode Ray Tube”, and it uses a small, high-brightness cathode ray tube as the image generating element.

6. GPS (Global Positioning System)

Mode: Data

Function: GPS stands for “Global Positioning System“, and it is a space-based satellite navigation output hardware device that helps to calculate the location of your device. The aim of GPS is to produce the result related to providing location, weather conditions, and also tracking.

GPS (Global Positioning System) consists 24 satellites, and it scaled in space about 12000 miles about the earth’ surface

7. Sound Card

Mode: Sound

Function: The sound card controls the output of sound signals, enabling devices like speakers and headphones to work. The sound card is known as an expansion card, which means it can be added to the motherboard. Although a sound card is not essential to a computer's basic functionality, you need one if you wish to play games, watch movies, listen to music, and use audio and video conferencing.

Types of Sound Card

• USB Sound Cards
• PCMCIA / PC Cardbus
• On-Board Sound Cards

8. Video Card

Mode: Visual

Function: As with the sound card, the video card is an expansion card that slots into the motherboard. The video card processes images and video, enabling visuals to be seen on a display. Most computers have basic video and graphics capabilities built into the computer's motherboard, but for faster, more detailed graphics, a video card is required.

9. Plotter

Mode: Visual

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.

Other Output Device Examples

• Computer Output Microfilm (COM, or Microfiche): COM is used to create a film image of the page sent from a computer.
• Plotter: A plotter interprets vector graphics files and draws lines between points.
• Television: A television (TV) is fed video and sound data which is output to the user in the form of synchronized sound and pictures.

Devices That Both Output and Input Data

• Modem: A modem sends and receives information over a telephone line or cables.
• Touch Screen: Touch screens accept input in the form of touch and display the output from the computer.
• Network Card (NIC): A network card is an expansion card for a computer that allows the device to connect to the network or internet.
