Output Devices Of Computer (Lession- 5)

Output Of Computer, Our previous research covered both the definition and nature of an output device. Taking a look at the output devices of a computer is the next step in this process. It is common knowledge that computers make use of output devices in order to show findings or information in a variety of forms, such as text, graphics, sound, or printed copies. A computer uses its output devices to obtain information and results. Now, let’s examine the top ten output devices used for this purpose. Here are a few examples of output devices:

Output Devices Of Computer

• Monitor
• Printer
• Speakers
• Projector
• 3D Printer
• Plotter
• GPS
• Headphones

Monitor :

Among the several types of output devices, a monitor is the most common example. Sometimes referred to as a Visual Display Unit (VDU), the primary purpose of a monitor is to display processed data, including photos, videos, text, audio, and various other types. A monitor creates its pictures by arranging little dots, also known as pixels, in a rectangular pattern. An image’s sharpness is directly proportional to the number of pixels that are present in it.

Printer :

Printers are yet another type of output device that is often used. The information that is communicated by the computer is made into a copy by the printer, which is often a hard copy or a Xerox copy. This is the primary function of the printer. It is the printer that is responsible for receiving electronic data from the computers and producing a tangible copy of the data that has been processed. Impact printers and non-impact printers are the two categories that are used to determine the classification of printers.

Speakers :

Speakers are the output devices that link to computers to enable sound output. Sound cards send signals to speakers, where they undergo audio processing. This allows speakers to function properly. There is a wide range of forms and sizes available for speakers, ranging from simple two-speaker output devices to very sophisticated multi-channel surround-sound systems. These speakers can adjust the loudness or amplitude of sound by using built-in amplifiers that vibrate at different frequencies.

Projector :

A projector, an output device that accepts pictures from a computer and allows users to display their output onto the screen, can project user output onto a wide area, such as a screen or a wall. The computer first sends the signal to a video card, which then relays it to the projector, which projects the pictures onto the surface. Using light and lenses, projectors enlarge images, including movies, photographs, and text. Therefore, it serves as an excellent output device for educating large audiences or delivering presentations to large groups of people.

3D Printer :

A 3D printer is an output device that prints layer upon layer of material based on digital models to create three-dimensional objects.

Plotter :

A plotter is a sort of output device that is used for the purpose of producing graphics, drawings, or large-format photographs of superior quality. Plotters are frequently used in engineering, architecture, and design, as well as other fields that demand precise and detailed graphical representations.

GPS :

The “Global Positioning System,” or GPS, is a radio-based satellite navigation system that consists of a constellation of several satellites. The Global Positioning System (GPS) is able to locate a precise position by using radio signals. The user transmits a radio signal to the satellites, which then gather data such as time, position, speed, and other factors and transport it to the receiving computer for processing. Users may then utilize this information to make decisions. GPS is considered an output device because it allows for the assessment of processed data to extract information.

Headphones :

We can use headphones, which are the output devices, to listen to the audio that a computer produces. With the assistance of headphones, we are able to listen to the audio in a private manner without bothering anybody else in the vicinity. These headphones come in a wide range of sizes and brands, and they can connect to computer systems either wired or wirelessly.

Sound, or audio, is produced by computers in the form of electronic impulses, which humans are able to experience by wearing headphones. The headphones can convert electrical energy into mechanical energy, enabling us to listen to music or audio on computer systems once this conversion has occurred. While computer speakers are cumbersome and bulky, headphones are lightweight and portable.
