What are Output Devices?

Output devices are any piece of computer hardware that transforms data into a form that can be understood by humans or, historically, into a form that can be physically read by machines and used with other non-computerized equipment. Text, graphics, sound, touch, or video are all acceptable. The following are some examples: displays, printers, audio equipment, headphones, speakers, projectors, GPS units, optical mark readers, and braille readers.

What is an Output Device?

Any peripheral that receives data from a computer and uses it for display, projection, or physical reproduction is known as an output device. An inkjet printer, for instance, is an output device that prints out whatever is displayed on a monitor. Two of the most popular output devices used with a computer are monitors and printers.

Types of Output Devices

There are numerous instances of devices in the list below. Pick any of the listings with blue text to learn more about the output device.

  • Monitor
  • Printer
  • Speaker
  • Headphones
  • Projector
  • Video Card
  • Sound Card
  • Speech-Generating Device
  • GPS

What Do You Mean By Output Device?

Any physical component used to transmit data from a computer to a different device or user is called an output device.

The majority of output peripherals are typically designed for human usage, thus they take the computer‘s processed data and convert it into audio, video, or physical copies.

Monitors and projectors (for video), headphones and speakers (for music), or printers and plotters are common examples of output devices (physical reproduction in the form of text or graphics).

Output Device Definition

Computers can connect with people and other devices thanks to output devices.

This can include peripherals such as network interface cards (NICs), modems, IR ports, RFID systems, and wireless networking devices that can be utilized for input-output (I/O) functions, as well as mechanical output devices such as solenoids, motors, and other electromechanical devices.

Output devices, in a contrast to input devices, are not strictly required for a computer to function.

However, without them, a computer may lose its usefulness because it cannot be understood how the data is currently being processed or what the system is doing.

For example, the user may ask the printer (the output device) to print a hard copy of that photo by clicking the “Print Screen” button on his keyword (the input device).

The printer would still be able to print that screenshot even if the user couldn’t see it because the second output device (the monitor) is not necessary to process this signal.

Other more or less frequent output devices include GPS units, which process satellite geolocation signals to calculate position and time, and speech-generating systems, which convert plain text into audible sounds.

What are the output devices in a computer?

Each computer has a GPU, an audio jack, and a display (either onboard or discrete). These are all output devices. Additionally, computers are often used alongside printers. Depending on the type of computer and how the computer is used, other devices may be used with the computer. The best way to identify all the output devices on your computer is to look at the list above.

Why requirement for output devices in computers?

Although you can work on a computer without an output device, you won’t be able to tell what the computer is doing. You can easily view and get the results of computer input using these devices. With the help of the output device, we can see, read and print the result we input.

What functions do output devices have?

To show the output, an output device uses a signal it receives from the computer to accomplish a task. An output device’s fundamental operation is listed below as an illustration.

  • If you enter “J” on a computer keyboard (input device), the computer receives the signal.
  • Once the input has been processed by the computer, a signal is sent to a monitor (output device).
  • The display (output) of the “J” on the screen occurs once the monitor receives the signal.
  • Another example of an output device is a printer, which might print that “J” if it were supported.

If the computer was working and had no output devices, you could still type “J” on the keyboard and it would still be processed. Without an output device, you cannot see what happened or the input could not be verified.
