Re: Need a metaphor for routing

I have to explain the difference between hubs, switches, and routers to
a audience with weak networking backgrounds so I need some simple (if
slightly inaccurate) analogies or metaphors. I'm considering the
following:

A hub is like a PA system what goes in is broadcast to all the outputs
(in the mike and out the speakers, in one port and out all others).

A switch is like a telephone switch board: it establishes
point-to-point connections (albeit you dial a phone and a switch
learns, but I'm not too concerned about that detail)

But how do I describe a router?

Continuing your telephone analogy, how about a router provides connections to switches in other area codes?
