OK folks, time to clear a few things up here.
Hubs -- These are basicaly a multi port repeater. Everything that comes in on one port goes out on all the ports.

Switch-- This will direct traffic to the correct port using the MAC address included in the packet header. The switch will build a table up over time, as it learns which address is at what port.

Router-- There are a few different classes of routers the most popular for home users is a "single protocal" router. It acts kind of like a switch, but instead of using MAC addresses, a router will use the TCP/IP address to route the packets. A router also will build a table of what address is on what port.
The other type of router is the "multi protocal router". This type will route based on the address in the packet using many different protocals, such as IPX, TCP/IP, APPLETALK. These are the kinda of routers found in large networks.

hope this helps
