what is Monitor?


what is Monitor?

Out of all the output devices, monitor is perhaps the most important, because it is the output device that people interact with most intensively.
Computer information is displayed, visually with a video adapter card and monitor.
Information processed within the CPU, that needs to be visually displayed, is sent to video adapter. The video adapter converts information from the formal used, in the same manner as a television displays information sent to it by a cable service.
TWO BASIC TYPES OF MONITORS ARE USED WITH MICROCOMPUTERS, WHICH ARE AS FOLLOWS:

1.      CRT

2.      LCD

Cathode Ray Tube (CRT):



The first is the typical monitor that you see on a desktop computer. It looks a lot like a television screen, and works the same way. This type uses a large vacuum tube, called cathode ray tube (CRT).

Liquid Crystal Displays:


The second type, known as a flat panel monitor, is commonly used with notebook computer. Most of these employ liquid crystal displays (LCDs) to render images.
Either of these types can be monochrome, displaying one colour against a contrasting back ground (often black), or displaying all colours.

When people talk about the capabilities of various monitors, one critical statistic is the resolution of the monitor. Today, most monitors have a resolution of at least 800 x 600 pixels. High-end monitors can have resolution of 1024 x 768 pixels or even 1280 x 1024 pixels. Thus both, monochrome and coloured monitors are available either in low resolution or in high resolution.
