What are DVI connectors?

What's the difference between DVI-I and DVI-D with respect to digital TFT displays? I know that there is a subtile difference in the pin configuration between the two and that one also has the capability to run an analogue signal through it (so you could still connect a CRT using this terminal). I also believe that one is downwards compatable but which one. Any insight into this topic or even a link to another techincal site would be greatly appreciated.

About DVI connectors

A DVI connection can be one of three types - DVI-I, DVI-D or DVI-A (very rare!) .

DVI-I:

DVI-I contains both the digital and analog connections, (DVI-D DVI-A) , it's essentially a combination of DVI-D and DVI-A cables within one cable.

DVI-D:

DVI-D (like DFP or P&D-D (EVC)) is a digital only connection If both devices being connected support a Digital DVI connection (DVI-I or DVI-D compatible) and are compatible in resolutions, refresh rates and sync, using a DVI-D cable will ensure that you are using a digital connection rather than an analog connection, without playing around with settings to assure this
