To give you a technical answer, your 10 or 100 base Ethernet port has a pair of wires that transmit data and a pair of wires that receive data. On a hub, the transmit and receive ports connections are reversed so that when you wire with a straight through cable the transmit on the hub is connected to the receive on your computer and vice versa. If you connect a computer to a computers or a hub to a hub you have to switch the receive and transmit connection so that the inputs still go to the outputs. For 1000 base it takes 4 pairs of wires for receive and four pairs of wire for transmit data. But since there are only 4 pairs of wire in the cable the send and receive share the same pins and circuitry selects which way to switch the connection. Therefore, 1000 base doesn't care, it sorts it out no matter what. -- G-Books is sponsored by <http://lowendmac.com/> and...
