    I know that FDDI is a sort of enhanced token ring set-up.
    It is a dual ring, 100Mbps technology that uses fibre optic cable :D

    What I am not sure about is if (this is going to sound daft tommorow) each ring has a token.
    Or is it that the second ring is purely for fault tolerance so if the first ring devolps a fault the second ring can merge to it :blink
    The seed of doubt in my mind contradicts the whole token ring technology as the sending computers have to wait for possesion. Unless of course the two rings are operating seperately :blink

    Looks like the second ring is for fault tolerance and is not used unless there is a failure of the primary ring.

    I thought that was what I was reading but you know what it is like when you have something in the back of your mind you want cleared up! :blink

    I don't think you will really need that detailing an understanding of FIDDI for the N+ Boyce. Just the cable it uses, it's speed and possibly what the initials stand for would probably be enough. :)

    Cheers Modey. That's what I like about David Groth's book. It covers the course in plenty of detail. :D
