CRT (Cathode Ray Tube) Monitors:

CRT stands for Cathode Ray tube. These monitors employ the Crt tachnology used most commonly in the manufacturing of television screens. In this, a stream of intense high energy electrons is used to from images on a fluorescent screen. A cathode ray tube is a basically a vacuum tube containing an electron gun at one end and a fluorescent screen at another end. From this electron gun, a process called thermionic emission generates a strong beam of electrones. These electrones travel thorugh a narrow path within the tube with high speed using various electro-magnetic devices and finally strike the phosphor points present on the fluorescent screen, thus creating an image**.

Advantages of CRT Monitors:

1. These moniotors are highly rteliable and efficient, and are capable of generating a resolution of up to 2048*1536 pixels. Thereby providing a clear picture quality. Also, CRT monitors that are now available are capable of producing thousands of different colors.

2. CRT monitors are affordable and cost effective.

3. Unlike conventional CRT monitors, modern technological advancements have resulted in the development of flat screen CRT monitors that reduce the glare and are good for the eyes.

Disadvantages of CRT monitors:

1. Heavy weight.
2. Occupy more place
3. High power consumption
4. High rediation and supports low resolution
