difference between DVI and regular video cable

I was just wondering if I should choose DVI or regular video cable to connect my computers monitor? what is the difference between them?

DVI

DVI (Digital Video Interface) is a specification created by the Digital Display Working Group (DDWG) to accommodate analog and digital monitors with a single connector. There are three different DVI configurations: DVI-A, designed for analog signals, DVI-D, designed for digital signals, and DVI-I (integrated), designed for both analog and digital signals.
Using a DVI connector and port, a digital signal that is sent to an analog monitor is converted into an analog signal. If the monitor is a digital monitor, such as a flat panel display, no conversion is necessary. Many monitors now include a DVI connection and many video adapters include a DVI port along with, or instead of, the traditional 15-pin Video Graphics Array (VGA) port.

Only use DVI if your LCD monitor has true DVI. Don't bother if it isn't going to be digital all the way.
. Of course your video card also has to have the DVI connector. There are several different DVI cables, so be sure to get the one that matches your system - they aren't cheap... You may need to check the mfr's web sites to determine the needed cable.
