Hi all

I like to know how things in my puter work but I have never been able to figure out how an 80 wire 40 pin UDMA IDE cable can alow faster data transfers over there 40 wire 40 pin counterparts?

I once asked a chap in my local puter shop and he said its done with multiplexing, though I have an understanding of multiplexing I am still non the wiser.

Can any one enlighten me?

The simple answer is that the additional wires act as 'sponges', absorbing electrical cross-talk that effectively limits the maximum data speed of the original 40 wire design.

As jazzypop say's they are extra earth cables that filter the signal
