In the architecture of a computer, one can see that a computer consists of Input devices, Output devices, Memory unit and CPU. We already have discussed the Input devices and the Memory units in other articles. In this article, we are going to discuss the 10 examples of output device for computer and their uses.
Examples of Output devices in computer
Some of the examples of the output devices used in computers are
- Sound Card
- Video Card
- Speech Synthesizer
What is output device in computer?
An output device is the electronic part of a computer that can convert the electronic information or the data into a readable form. These output devices give electronic data in the form of human languages. For example – a Monitor shows the readable text, images, videos, and other files on the screen. Again, a printer gives the printed documents which can be read physically.
Output device for computer with use:
Here are the 10 examples of output device for the computer with their uses. Check the list of output devices and their uses at below.
The Monitor is the all-time used output device in a computer. It is used in Computers, Laptops, TVs, etc. The main component of a Monitor is its screen. Monitor displays all the information on the screen. A monitor is basically the coordinator between the CPU of the computer and the users. Users can view the soft copies of a file, text, photos, graphics, tables, and videos on the screen of the Monitor.
In the early days, the available screens were the Cathode Ray Tube (CRT) or the fluorescent screens. But in recent days LED screens, screens of plasma, liquid crystal display (LCD) are the very much popular monitor screens for the TVs, computers or the laptops. Different sizes of the Monitor or screens are also available.
Some of the popular Monitor displays or screens are –
- CRT Screen (Cathode Ray Tube Screen)
- LED Screen (Light Emitting Diode made screen)
- LCD screen (Liquid Crystal Display)
- OLED screen (Organic Light Emitting Diode based monitors)
- Plasma Monitor
The Printer is one of the most popular and frequently used output devices in computers and PCs. Printers are the external devices that can provide electronic data in the paper-printed form. That means a printer converts the soft copy of the data or information into the hard copy. It uses paper and ink to print the data. The quality or the resolution of the image of the printed data is measured in the unit of dots per inch (DPI). In the early days printers use to print only Black and white images, but in modern days colored printers are also available.
Another popular output device is Speaker. It is a hardware output device that produces the audio files of the electronic data. A speaker converts the electrical signal into a sound wave. It receives the analog audio from the sound card and amplifies the sound. Computers, Laptops, TVs, Smartphones, Androids use speakers to represent the information in audio form. Speakers may be in-built in computers or externally connected to the computers.
Using Plotter one can print the graphics, maps, charts, advertising signs, etc. with high-quality images and different colors. Printers not only print on plain papers but also on cardboards, films, T-shirts, bags, cups, and other synthetic materials. This makes the plotters different from the printers. Electrostatic plotter and cutting plotter are the two types of plotters.
Better accuracy and high-speed response make the plotters useful in engineering fields such as the drawing of the building plans, maps, city planning, etc. Companies print their brand name or other images on the products with the help of plotters.
Projectors project images or videos or animations of electronic data on the wall or screen. A projector can be used in seminars, conferences, meetings, cinema theatres to represent the discussion in image or video or in graphics form. Projectors can produce both 2D and 3D images of an object. In modern classrooms, teachers are using projectors instead of boards to arrange the lectures.
Almost all Smartphone and iPhone users use headphones. The Headphone is also a popular output device. This hardware output device is also known as the earphone. It produces an audio file of electronic information or data. It is similar to a speaker, but they are different in construction and amplification power. In digital technology, the headphones have many advantages over the speakers in listening to an audio file. Using headphones or earphones the users can listen to the audio without any external disturbance. Nowadays, all the headphone companies producing headphones with an input jack of 3.5 mm diameter which is suitable for almost every smartphone and laptop. JBL, Sony, Bose are the most popular headphone brands.
Advantages of a headphone over a speaker:
- Headphones can be used privately.
- Headphones are almost noise-free.
- One can buy a headphone with low cost.
- One can listen to audio without any external disturbance by using headphones or earphones.
The full form of GPS is Global Positioning System. It is also an output device. GPS is satellite navigation that can collect and send the data or information related to the position of an object, time, vehicle speed, etc. It uses microwaves to communicate with satellites. We are very much familiar with the GPS system in google maps. GPS can also be used to reduce crimes. Police can track the criminals by GPS location. People can find their destination easily by using GPS tracking. Also, one can know about the Weather condition by using GPS.
Sound cards have significant applications to create sounds. We already know that in listening to the audio files we have the output devices like speakers and headphones. But the sound card is the device that enables the speakers and the headphones to work. Sound card converts the digital audio files into analog form and transfers it to the speakers or the headphones to create the sound wave.
The Sound card may be in-built or externally connected. It produces high-quality analog sound signals which helps in listening to the audio files clearly via speakers or headphones. Sound cards are more useful in gaming.
The Video card is a hardware output device. All the Computers and laptops have in-built video cards. A video card or the video adaptor converts the digital signal into image or video form. This enables us to watch the images and videos smoothly and stably on the screen of computers and laptops. Video cards are the video counterparts of sound cards. Both are very much useful in Gaming and 3D animations.
Speech Synthesizer is one of the latest output devices for computer applications. It is an electronic device that can produce human speech artificially. It is available in both hardware and software form. A Speech synthesizer can convert the text into speech.
