What are the function of output device?
Output devices relay the response from the computer in the form of a visual response (monitor), sound (speakers) or media devices (CD or DVD drives). The purpose of these devices is to translate the machine's response to a usable form for the computer user.
What is the signal sent from the input device to the computer?
A signal is sent from an input device to the computer (e.g. the user clicks with the mouse on the “play” button of a video). The computer processes the input and then sends a new signal to the output device (e.g. the monitor and speakers).
How does an output device work?
In order to work, an output device needs to receive a signal from the computer after the information it has processed is ready to be displayed into its new format (e.g. audio or video). The process usually follows certain steps:

Is an output device necessary for a computer?
Unlike input devices, output devices are not strictly necessary for a computer to operate. However, without them the purpose of a computer may be defeated since there’s no way of determining how the data is currently processed or what the system is doing.
What is monochrome monitor?
A monochrome monitor is a type of CRT computer display which was very common in the early days of computing, from the 1960s through the 1980s, before color monitors became popular. The most important component in the monitor is the picture tube. CRT basically means cathode ray tube. The CRT use cathode-ray-tube technology to display images, so they are large, bulky and heavy like conventional or old televisions, because old televisions also used the CRT technology only to display the television films or television images. To form the image on the screen, an electronic gun sealed inside a large glass tube fires electrons at phosphorous coated screen to light up the appropriate pixels in the appropriate color to display images. The phosphors glow only for a limited period of time after the exposure of the electrons, the monitor image must be redrawn/refreshed on a continual basis. Typical refreshment rates are between 60 and 85 times in a second.
How many colors are there on a monochrome monitor?
Monochrome monitors actually display two colors, one for the foreground and one for the background. The colors can be black and white, green and black, or amber and black. The Colored Monitor is a display device capable of displaying many colors. The Color monitors can display anywhere from 16 to over 1 million different colors.
How many colors can a color monitor display?
In contrast, a monochrome monitor can display only two colors one for the background and one for the foreground. Color monitors implement the RGB color model by using three different phosphors that appear red, green, and blue when activated. By placing the phosphors directly next to each other, and activating them with different intensities, color monitors can create an unlimited number of colors. In practice, however, the real number of colors that any monitor can display is controlled by the video adapter.

What is a projector?
A projector is a display output device because it receives images from a computer and transfers those computer images to a wall, surface, or projection screen. Specifically, the computer first sends the signal to the video card, which then transmits the signal to the projector to project the images on the surface.
What is a VDU monitor?
It is also known as VDU (Visual Display Unit). It consists of several components, such as screens, circuitry, power supplies, screen adjustment buttons, and more, which are assembled into a casing. The monitor provides output from a computer on a screen so that users can interact with or view data digitally.
1. Monitor
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.
2. Printer
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:
3. Plotter
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.
4. Projector
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.
5. Speakers
Speakers 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.
6. Headphones
To hear the sound, use earbuds with your PC, 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.
7. Sound Card
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.

Auditory
A speaker is an output device that produces sound through an oscillating transducer called a driver. The equivalent input device is a microphone.
Speakers are plugged into a computer's sound card via a myriad of interfaces, such as a phone connector for analog audio, or SPDIF for digital audio. While speakers can be connected through cables, wireless speakers are connected to the host device through radio technology such as Bluetooth.
Tactile
A refreshable braille display outputs braille characters through the use of pins raised out of holes on its surface. It is ordinarily used by visually-impaired individuals as an alternative to a screen reader.
Haptic technology involves the use of vibration and other motion to induce a sense of touch. Haptic technology was introduced in the late 1990s for use in game controllers, to provide tactile feedback while a user is playing a video game. Haptic feedback has seen further uses in the automotive field, aircraft simulation systems, and brain …
Printing devices
A printer is a device that outputs data to be put on a physical item, usually a piece of paper. Printers operate by transferring ink onto this medium in the form of the image received from the host.
Early printers could only print text, but later developments allowed printing of graphics. Modern printers can receive data in multiple forms like vector graphics, as an image, a program written in a page description language, or a string of characters.
Headless operation
A computer can still function without an output device, as is commonly done with servers, where the primary interaction is typically over a data network. A number of protocols exist over serial ports or LAN cables to determine operational status, and to gain control over low-level configuration from a remote location without having a local display device. If the server is configured with a video output, it is often possible to connect a temporary display device for maintenance or administration purposes while the server continues to operate nor…
