As a friendly FYI: 10+ years ago, the term crossover cable meant that
the ethernet cable in question had the relevant input and output wires
switched from a normal ethernet cable, so that the output of port A
talked to the input of port B and vice versa.

This was necessary/convenient if you wanted to have two machines
communicate and you did not have a hub or switch available (and a second
ethernet cable).

Since ~2005, however, no special crossover cable is needed as all (to my
knowledge, anyway) ethernet cards have built-in hardware logic to
auto-negotiate which wires are input and output upon connection. So,
when he says "crossover cable", you can translate that in your mind to
just "cable". (Unless of course you're working with hardware older than
2005!)

Cheers,

Kevin
