Tech:

A hub broadcasts signed packets: (192.168.0.2 / 192.168.0.3 /192.168.0.4 ) down a single wire. This is a holdover from old (like me) linear network configurations (daisy chains). Hubs are slow when you have more than 2 computers on the network.

Now. Routers are smarter. They send it down the right wire. (a 'star' configuration).

Christ. I hate technology.
