What Is An Output Device?

Complete Information About What Is An Output Device?

Complete information about what is an output device: The computer gives instructions and data from Input Devices and processes it and returns the results. To show this result, he needs some special equipment. Which are called Output Devices?

In this lesson, we will give you complete information about the computer's output devices. We have selected the major output devices here. Which are the most popular and used? Because the output device can also change according to the result.

Monitor

Monitor, also called VDT - Video Display Terminal and VDU - Video Display Unit. The main output of the computer is the Output Device. Which is used by Computer Output Display? These outputs can be Video, Text, Images, anything.

Monitor uses Pixels to display any output. The more Pixels, the more the object will be clean. You can consider Pixels a Dot.

The design of the monitor is similar to that of your TV. Which includes things like Screen, Button, Power Supply, Case, etc. These monitors are divided into two categories based on their manufacturing technology.

1. CRT Monitor
2. FPD Monitor

1. CRT Monitor

The CRT's full name is Cathode-Ray Tube. CRT is an Electron Beam. Which revolve on the screen. It is called Pixel in a common language. The more CRTs on the screen, the more quality the object appears.

A CRT Monitor is like your old TV. Which is also very heavy. And also consumes more electricity. These monitors were mostly used in third and fourth generation computers.

2. FPD Monitor

FPD's full name is Flat-Panel Display. Which is a thin screen? Which you can hang on the wall, wear in your hand. They are very light, small and strong. They are used in Calculators, Digital Clocks, Laptop Display, Smartphone Screen, etc.

You can think of FPD as a TV hung on the wall. Which you also know as LCD - Liquid Crystal Device and LED - Light Emitting Diodes. Nowadays the only LCD and LED Monitors are used in computers.

Speaker

A speaker is an output device that the computer uses to provide sound output. Songs you listen to the dialogues of movies. They are all heard by the speaker. The computer tells the sound results through the speaker itself.

Printer

The printer is another important output device. Stored Digital Data is printed on paper on computer. When data is printed on paper, it is called Hard Copy. And on a computer, it is called Soft Copy.

We can print the data available on the computer in many types and quality. For this, we need different types of printers. Whose names are given below?

1. Dot Matrix Printer
2. Drum Printer
3. Line Printer
4. Laser Printer
5. Inkjet Printer
6. 3D Printer

Projector

The projector is an output device that is used to display computer images, videos, texts, or other items on a wall or other flat surface. He sends light to the wall for this work called Projecting. Hence this device is called Projector.
The projector acts as a monitor that displays the output on something else. It is used a lot in Business Meetings, Class Room Teaching, Public Shows, Theaters, etc. The output of the Projector is larger, flat and more colorful than the actual size.

Headphone

The headphone can also be used for sound output. But through this, you can also give Sound Input to the computer. Through this, you can record your own voice. Hence it is also called the Input Device.

What Have You Learned?

In this lesson, we have provided you complete information about the Output Devices of the computer. You have learned that different output devices are used in computers for different tasks. We hope that this Lesson will prove useful to you.
