Its the maximum rate that bits that can be transferred over the wire. Whatever protocol runs on the wire subtracts from the bit rate. There there's the question of utilisation, there will be times at which nothing's actually happing on the bus (depending on the protocol). -- Barry Barry@netbox.com ------ (I should put something down here).
