1. Output devices allow to convert the electronic information into the humans readable format. This format may be audio, visual, textual, or hard copy such as printed document.

2. There are different types of output devices, which are used for displaying processed data into various formats; below explain each one – 1.Monitor 2.Printer 3.Headphones 4.Computer Speakers 5.Projector 6.GPS 7. Sound card 8. Video card 9. Braille reader 10 Speech Synthesizer 11. Plotter

3. The monitor is commonly used as output device because it helps to show all result as the e graphical form. User requires serving the power supply to the computer monitor. The monitor is getting to link via VGA cable to CPU (Central Processing Unit). Monitor has two elements like as cathode ray tube and a fluorescent screen.

4. Printer is a hardware device that helps to provide the hard copy version, after getting of processed data from computer. A printer allows to users for getting output in the form of text and graphic format.

5. Headphones are also called the “Earphone“, and user can plug headphone with computer, mobile, and laptop to hear the voice. Mostly, users use the headphones to hear the sound without getting any hindrance to other person. They are also output device of computer.output device of computer Firstly, Headphone was developed for using in the US navy, in 1910.

6. Computer speakers are output hardware devices, which are connected with computer for getting sound. Computer’s sound card allows to generate sound with using of the signals, which come from speaker. Commonly, computer speakers consist the internal amplifier that allows to enhance level of volume as per the need of users.

7. Projector is an output hardware device that allows to user to project the output on the big screen, wall, or other large surface. Projector enables to light and lenses to provide magnified text, image, and videos. Mostly, projectors are used offices for showing their presentations at the front of clients, classrooms, places of worship, auditoriums, and watching movies with enabling group of people.

8. GPS stands for “Global Positioning System“, and it is a space-based satellite navigation output hardware device that helps to calculate the location of your device. The aim of GPS is to produce the result related to providing location, weather conditions, and also tracking.GPS GPS (Global Positioning System) consists 24 satellites, and it scaled in space about 12000 miles about the earth’ surface. Today, you can use “Global Positioning System” in your smart phone, vehicle, and other tracking devices.

9. Sound card is also called as the “Audio Adapter“, and it is a expansion card or integrated circuit that is embedded on the different types of motherboard. Sound card receives the signals from motherboard then process them, and finally convert them into audio. It helps to increase the audio experience. Sound card is very helpful for watching video, playing game, listen music, when you need. types of motherboard

10. Video card is an expansion card that is embedded on the motherboard, and it helps to enhance the quality of video and other graphical content. Video card allows to increase the experience of playing game, photo, watching movies, etc. Now these days, video card is attached by default inside the computer, but if you want to boost up your visual elements then it can be added as externally.

11. Braille reader is a electronic hardware device that is very helpful for blind people for getting to read texts, which are displayed on the monitor screen. There are several kinds of Braille reader such as large units of keyboard size for computer system and small units for tablets and laptops.

12. Speech synthesizer is a speech generating device that helps to convert text to speech. Speech synthesizer speaks out loud the commands, which are inputted by the use in the form of text. It is very helpful for individuals suffering from speech impairments.

13. Plotter is also hardware output device that is similar to printer but it allows to print wide format materials such as banners, brochures, pamphlets, etc. Mostly, plotters are used in the engineering and basically draw a certain image on a number of straight lines.
