Which devices typically generate computer output?

Computer output devices get information from the computer and transmit data that has been processed to the user. Output devices can provide data in various formats, including audio, visual, and hard copy media. These devices can be used for projection, display, and physical reproduction. Two of the most common output devices that are used with computers include printers and monitors.

All peripheral hardware is called computer output devices. They can be connected to a computer via cables or wireless networking.

There are many reasons to have an output device.

Without an output device, a computer can still work. Without an output device, however, it’s impossible to know what the computer is doing. There are no indicators of errors or the need for additional input. The computer will still work if the monitor is removed from it, but it won’t be very useful.

Examples of Output Devices


This is the most commonly used computer output device. This device creates a visual display that allows users to view processed data. There are many sizes and resolutions of monitors.

There are several types of monitors.

  • Cathode Ray Tube: This uses a bright dot to create the pixels that makeup displayed images.
  • Flat Panel Screen – This uses liquid crystals and plasma to generate output. To create pixels, light is transmitted through the liquid crystals.

A video card is the heart of all monitors. It can be positioned on the motherboard or in an expansion slot. The video card converts the computer data into images the monitors can display.

This device creates a hardcopy version of processed data such as documents and photos. The image data is transmitted to the printer by the computer. This then creates the image on paper.

Types of printers

  • Ink Jet – This printer sprays small ink dots onto a substrate to create an image.
  • Laser – This type uses toner drums that can roll through magnetized pigment and then transfer the pigment onto a surface.
  • Dot Matrix: Dot matrix printers use a print head to create images on a surface using an ink ribbon. These printers were popularly used in 1980 and 1982.


Speakers are speakers that are attached to computers for sound output. Sound cards are needed to allow speakers to work. There are many speakers, from simple two-speaker units to multichannel surround sound systems.

A headset is a combination microphone and speakers. This is a popular tool for gamers, but it can also be used to communicate with friends and family over the internet via VOIP programs.


The projector is a display device that projects a computer-generated image onto another surface, usually a whiteboard or wall. The image data is transmitted to the computer’s video card. This then sends the video image directly to the projector. It is used most frequently for watching videos or making presentations.


This generates a hardcopy of a digitally drawn design. The plotter receives the design via a graphics card. Once the design has been sent, the plotter forms the design using a pen. It is used for engineering purposes and draws an image using a series of straight lines.

Video Card

Mode: visual

Function The video card is an expansion that fits into the motherboard, just like the sound card. The video card can process images and video to enable visuals to be displayed on a monitor. Although most computers already have basic video and graphics capabilities, a video card is needed for more detailed and faster graphics.

Sound Card

Mode: Sounds

Function The soundcard controls the sound signal output, which allows devices such as headphones and speakers to work. It is also known as an extension cord. This means that it can be added to the motherboard. A sound card isn’t essential for a computer to function properly. Still, it is necessary if you want to use audio and video conferencing, play games, or watch movies.

GPS (Global Positioning System)

Mode: data

 Function GPS: A radio-based navigation system, GPS consists of a sender and receiver. The sender transmits signals to 24 satellites and pings the receiver with the sender’s exact location in the form of latitude and longitude coordinates. Satellites transmit information to the GPS using microwave signals. This includes vehicle speed and location.
