Etherswitches learn which ports are using what MAC addresses, and only direct traffic to the right ports. Etherswitches are basically bridges with lots of ports. They even support bridging protocols like 802.1d to support networks with lots of interconnected switches. A hub is just a repeater. It may detect some kinds of errrors, but probably just jabber errors. Tom
