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.
OR
Based on the command given by you, the information processed is given to you by the output computer which is received by you output device or output unit. Out device is hardware. Output device is the best example of your computer monitor. This is called I / O devices -
In this lesson, we will give you complete information about 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.
Output Devices-आउटपुट डिवाइस
- Monitor
- Speaker
- Printer
- The projector
- Headphones
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-CRT मॉनिटर
The CRT's full name is Cathode-Ray Tube. CRT is an Electron Beam. Which revolve on the screen. It is called Pixel in common language. The more CRTs on the screen, the more qualit 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 मॉनिटर
FPD stands for Flat-Panel Display. Which is a thin screen. Which you can hang on the wall, wear in your hand. It is very light, small and strong. They are used in calculators, digital clocks, laptop displays,smartphone screens etc.
You can consider FPD to be a TV hanging on the wall. Which you also know as LCD-liquid crystal device and LED-light emitting diode. Nowadays only LCD and LED monitors are used in computers.

Printer-प्रिंटर
Printer is another important output device. The use of which Stored Digital Data is printed on paper in the 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 in computer in many types and quality. For this, we need different types of printers. Whose names are given below.
1.Dot Matrix Printer(डॉट मैट्रिक्स प्रिंटर)
2.Drum Printer(ड्रम प्रिंटर)
3.Line Printer(लाइन प्रिंटर)
4.Laser Printer(लेजर प्रिंटर)
5.Inkjet Printer(इंकजेट प्रिंटर)
6.3D Printer(थ्री डी प्रिण्टर)
Projector-प्रक्षेपक
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 a light to the wall for this work which is called Projecting. Hence this device is called Projector.
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 Projector is larger, flat and more colorful than the actual size.
Headphone-हेड फोन्स
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 Input Device.
