DVI-I and DVI-D

Could someone please tell me what the difference is between DVI-I and DVI-D? Is one better than the other?

Thanks.
 
Thanks for the informative article. A few questions arose from this:

Does DVI-D have better image quality than DVI-I since DVI-D is fully digital?
If my monitor is DVI-D only, can I plug it into DVI-I port on a video card that only has DVI-I?

DVI-I = DVI-D + support for analog output (usually via a DVI->VGA adapter cable, although technically you could create a "DVI-A" input that would accept the analog over a DVI-I cable). There's no 'loss' in quality; it just lets you transmit either DVI or VGA through the DVI-I output.
 
There is no quality differences between DVI-I and DVI-D. The analog part (DVI-A)is just there to give the end user the flexibility to add a DVI-A to VGA adapter so you can use the DVI-I port for an analog monitor if you want to use the video card to run two analog monitors (like a pair of CRTs).

The DVI cable for a LCD flat panel simply connects the DVI-D part of the DVI-I port to the DVI-D input of the panel. Since there are no pins on the cable coonector to plug into the DVI-A section, the monitor never knows they are there, so it doesn't make a difference to the monitor if the port is a DVI-I or a DVI-D.
