I have always wondered why there are "crossover" and "straight through" network cables! I was trying to find some information on the net, but can only find info on how to use them. Maybe somebody here knows?
I know the basic concept, like for going between two NIC's you need the "send" on one end to end up at the "receive" on the other end, hence the crossover, but why not just wire the ports on the hardware (switches, etc.) just like a NIC? Then you would only ever need crossover cables, right? There must be some reason for this-
