A peripheral device that helps a computer system to reproduce input data or instructions is called an output unit of a computer. After a user enters the raw data as input, the processor receives that information and processes the data. Then, the computer system distributes the processed data to the users through various output units. Output devices transform computer data into a human-understandable form. This tutorial is an easy way to learn more basic ideas on the different types of output devices and their utility.

What Are Output Devices?

Output devices are computer hardware capable of presenting desired output to the users. Its initial function is to transform and present that information into a human-understandable layout. Many output devices display the outcomes in various ways such as image, text, soft copy, hard copy, video, audio, etc.

Different Output Devices

Monitor

A computer system's prevalent output device is a monitor, usually termed the Visual Display Unit (VDU). It can portray the processed data in many ways, like text, videos, images, audio, and many more. It constructs these images by collecting microscopic dots in a rectangular pattern called the pixels. More numbers of pixels describe the acerbity of an image.

Monitors can be of many types. These are as follows:

Cathode-Ray Tube (CRT)

Plasma Screen Monitor

Printer

A printer is that output device of the computer system that helps the user print their document or any file. This document can be of any variety, such as text, image, or combination of both. When a user instructs a computer to print as needed, the processor processes it, and finally, the result is conveyed as a printed document that the user can physically access. Based on the printing style, the printers are of two different types, one is Impact Printers, and the other is Non-impact Printers.

Plotter

A plotter is a device helping its users; print drawings in high quality, in different forms of colors. It functions similarly to a printer, though it has more evolved functionalities. It is generally in printing large maps, blueprints of ships, buildings, architectural sketches, large-format printing, and assembling pictures, 3D postcards, advertisement signs, diagrams, and various designs of the inner structure of building machines. It creates line drawings on paper, employing multiple colors with automated pens producing graphs, sketches, charts, maps, etc. There are two types of plotters, namely drum plotters and flatbed plotters.

Speaker

Speakers are there for the computers to authorize sound as an output. Also, speakers comprise a sequence of amplifiers that reverberate at distinct frequencies, furnishing a significant potency to the signal, which is why users can hear a loud sound. They accept the audio input signals from the computer's sound card resulting in sound waves as audio outcomes.

Projector

A projector is a device that permits the users to project their output in a large area or a large screen. Users can use it to display the results of a computer and other devices onto a screen. It heightens texts, images, and films employing light and lenses. As a result, it becomes an ideal output device for providing presentations or teaching many audiences.

Video Card

A Video Card is an extension card through which a computer can share graphical data to a video display unit such as a TV, monitor, or projector. It processes photos, videos, and sound with additional functionalities; that the CPU typically executes. Since video cards have an adequate processing ability, Gamers and video RAM uses video cards. The video card permits the computer to fetch video or graphical messages to its user, having improved clearness.

GPS

Global Positioning System (GPS) is a satellite-based navigation technology that uses radio signals to locate precise locations. The sender device sends a radio signal to the satellites. Then the satellites compile information about location, time, speed, and other aspects and transmit it to the computer receiver for processing. This processed data can be interpreted to obtain information and, thus, can be included in the collection of data output devices.

Speech Synthesizer

A speech synthesizer is a mechanical device that accepts raw data, analyzes it, and produces audible words. It can be a computer card or a box fastened by a cable or software functioning with the system's sound card.

Computer output devices receive information from the computer and carry data that has been processed by the computer to the user. Output devices provide data in myriad different forms, some of which include audio, visual, and hard copy media. The devices are usually used for display, projection, or for physical reproduction. Monitors and printers are two of the most commonly-known output devices used with a computer.

Computer output devices are all peripheral hardware and are connected to a computer by cables, or by wireless networking.

Reasons for Having an Output Device

A computer can still function without an output device. However, without an output device, there's no way to determine what the computer is doing. There is no indicator of errors, nor of the need for additional input. For example, if you detach your monitor from your computer, the computer will still function, but it's not going to be very helpful.

Examples of Output Devices

Monitor - This is the most common computer output device. It creates a visual display by the use of which users can view processed data. Monitors come in various sizes and resolutions.

Common Types of Monitors

Cathode Ray Tube - this uses phosphorescent dots to generate the pixels that constitute displayed images.

Flat Panel Screen - this makes use of liquid crystals or plasma to produce output. Light is passed through the liquid crystals in order to generate pixels.

All monitors depend on a video card, which is positioned either on the computer motherboard or in a special expansion slot. The video card sorts out the computer data into image details that the monitors can then show.

Printer - this device generates a hard copy version of processed data, like documents and photographs. The computer transmits the image data to the printer, which then physically recreates the image, typically on paper.

Types of Printers

Ink Jet - this kind of printer sprays tiny dots of ink onto a surface to form an image.

Laser - this type utilises toner drums that roll through magnetized pigment, and then transfers the pigment onto a surface.

Dot Matrix - dot matrix printers utilise a print head to set images on a surface, using an ink ribbon. These printers were commonly used between 1980 and

Speakers - speakers are attached to computers to facilitate the output of sound; sound cards are required in the computer for speakers to function. The different kinds of speakers range from simple, two-speaker output devices right the way up to surround-sound multi-channel units.

Headset - this is a combination of speakers and a microphone. It is mostly used by gamers and is also a great tool for communicating with family and friends over the internet using some VOIP program or other.

Projector - this is a display device that projects a computer-created image onto another surface: usually some sort of whiteboard or wall. The computer transmits the image data to its video card, which then sends the video image to the projector. It is most often used for presentations, or for viewing videos.

Plotter - this generates a hard copy of a digitally depicted design. The design is sent to the plotter through a graphics card, and the design is formed by using a pen. It is generally used with engineering applications and essentially draws a given image using a series of straight lines.

Input/Output Devices

Input/Output devices don't only produce output, but can also be used as storage and input devices. The computer transmits data to the drive, where it is saved and can be later accessed.

Examples of I/O devices are CD drives, DVD drives, USB drives, hard disk drives (HDDs), and floppy disk drives.

CDs and DVDs are two kinds of optical disc that save data in a digital format. Data is written onto the disc using a laser writer that embeds the data directly into the disc's coating.

A floppy disk is a magnetic storage device. A layer of a magnetised material is placed within a proactive plastic casing. The computer then embeds the data into the magnetized material, by using a writing head.

Output Devices are those devices which show us the result after giving the input data to a computer system. Output can be in different forms like image, graphic audio, video, etc.

What is an Output Device?

Any peripheral that accepts data from a and prints, projects, or reproduces it is known as an output device. The output may be audio, video, hard copy - printed paper, etc. Output devices convert the computer to human understandable form. We give input to the computer using input devices and the computer performs operations on the data and displays the output to the user using the output device.

How Does an Output Device Work?

In order 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 'Hi Geeks' on a computer keyboard (input device), the computer receives the signal.

Once the input has been processed by the computer, an output device-a monitor-is signalled.

The display (output) of the 'Hi Geeks' on the screen occurs once the monitor receives the signal.

Another example of an output device is a , which might print that 'Hi Geeks' if it were supported.

If the computer was working and had no output device attached, you could still type 'Hi Geeks' on the keyboard and it would still be processed. Without an output device, you couldn't see what happened or verify the input, though.

Different Types of Output Devices

The various output devices are as below:

A computer's principal output device is a monitor, often known as a visual display unit (VDU) . It displays the processed data like text, images, videos, audios, etc. It makes images by arranging microscopic dots in a rectangular pattern, known as pixels. The sharpness of an image is determined by the number of pixels. There are two types of monitor viewing screens:

Cathode-Ray Tube (CRT): This type of monitor is based on a cathode ray tube. In which the cathode ray tube generates a beam of electrons with the help of electron guns they strike on the inner surface of phosphorescent of the screen to generate images. The CRT monitor holds millions of phosphorus dotes in three different colors, i.e., red, blue, and green. These dots glow when the beam struck on them and create an image. The main parts of the CRT monitor are the electron gun, fluorescent screen, glass envelope, deflection plate assembly, and base.

Display on a Flat Panel Monitor with a Cathode-Ray Tube (CRT): A flat-panel display is a type of video display with less volume, weight, and power consumption than a CRT. They can be put on the wrist or hang on the wall. Calculators , video games, monitors, , and graphical displays all use flat-panel displays.

Plasma Monitor: It is also a flat panel display but it is based on plasma display technology. In a plasma monitor, a small cell is present in between two glass surfaces and these cells contain a solution of noble gases and mercury. So when the electricity supply on the gas present in the cell converts into plasma and produces UV light that creates an image. It is much better than an monitor. The resolution of this monitor is also high up to 1920 x 1920. It has a good contrast ratio, high refresh rate, etc.

Characteristics of Monitor:

Resolution pixels: Pixels are the smallest element of any image

Size: The size of the monitor is diagonal measurement of a desktop screen is typically 14 to 25 inches.

Refresh Rate: Total number of times per second that an image on a display is repainted or refreshed.

Printers are information output devices that allow you to print data on paper. Or in other words, it is an output device that creates a hard copy of the processed data or information. Printers are divided into two categories:

Impact Printer: In impact printers, characters are printed on the ribbon, which is then smashed on the paper. Or we can say that such type of printer uses a print head or hammer to print the data on the paper. Here to print the paper the hammer or print head strikes an ink ribbon against the paper and the character starts printing. Some of the types of impact printers are:

Impact printers have the following characteristics:

Extremely low consumable costs.

Fairly noisy

It's perfect for large-scale printing because of its inexpensive cost.

Physical contact with the paper is required to form an image.

Non-Impact Printers: Non-impact printers print characters without the use of a ribbon. These printers are often known as page printers because they print a full page at a time. Some of the types of non-impact printers are:

Non-impact printers have the following characteristics:

They don't produce much noise.

Superior quality.

Supports a wide range of fonts and character sizes.

A plotter is a device that prints high-quality graphics in a variety of color formats. It works in a similar way to a printer, although it has more advanced features. It is used to print large maps, architectural drawings, large-format printing, and create pictures, 3D postcards, advertising signs, charts, and various designs of the internal structure of building machines, as well as create pictures, 3D postcards, advertising signs, charts, and various designs of the internal structure of building machines.
Characteristics of Plotter:

Large size prints can be taken via plotters.

It is slow and expensive.

A projector is a device that allows users to project their output onto a large area, such as a screen or a wall. It can be used to project the output of a computer and other devices onto a screen. It magnifies texts, photos, and movies using light and lenses. As a result, it's an excellent output device for giving presentations or teaching big groups of people.
Characteristics of Projector:
are connected to computers to allow sound to be output. For the working of speakers, sound cards are required. From simple two-speaker output devices to surround-sound multi-channel sets, speakers come in a variety of shapes and sizes. They take audio input from the computer's sound card and output sound waves as audio output.
Characteristics of Speakers:

Speakers are available in a wide range of qualities and prices.

Small, plastic computer speakers with low sound quality are often included with computer systems.

To hear the sound, use earbuds with your computer, laptop, or smartphone . It enables you to hear the sound without causing any inconvenience to others. To translate electronic signals into sounds without causing inconvenience to others. They can be wired or wireless and can be connected to computers, laptops, mobile phones , etc. They are connected with the devices via Bluetooth.
Characteristics of Headphones:
Sound cards are computer output devices that are inserted into the computer. A sound card, either external or internal, is required to produce sound on any computer (built-in). An external sound card enables for better overall sound generation and is required for wide and clear sound recording, as well as sound without noise and interference.
Characteristics of Sound Card:
An extension card via which a computer can transfer graphical data to a video display device like a TV, or monitor . It processes photos and video, as well as other functions that the CPU generally does. As they have a good processing capability and video , Gamers utilize video cards.
Characteristics of Video Card:

Heat sinks are required for video cards with high performance as they generate a lot of heat.

Also known as graphics card and require installation in addition to the hardware.

When working with huge files, video cards supply a significant quantity of video-only memory that frees up CPU resources, allowing the system to run more effectively.

9. Speech Synthesizer

A speech synthesizer is a computerized device that takes in data, interprets it, and generates audible words. It might be a computer card, a box connected by a cable, or software that works with the computer's sound card.
Characteristics of speech synthesizer:
The Global Positioning System (GPS) is a radio-based satellite navigation system that uses radio signals to pinpoint a specific position. The sender sends a radio signal to satellites, which collect data such as time, location, speed, and other variables and deliver it to the reception computer for analysis. Because this processed data can be evaluated to obtain information, it is considered as an output device.
Characteristics of GPS:

GPS satellites constantly communicate their position and time.

Solar storms , high storm cover, and other factors impair GPS equipment.

The Global Positioning System (GPS) is based on the mathematical idea of trilateration.

The GPS works independently of telephonic or reception and does not need the user to send any data, however, to improve accuracy both technologies can be used.
