Definitely not true. Each machine needs only *one* Ethernet jack.
A multi-port router has a (4 or 5 port) switch built into it so that
you access the internet *and* the other machine over the same wire.
Plug your cable modem and Macs into this one unit, and then they'll
all see each other.

Is "common sense" really valid?
For example, it is "common sense" to white-power racists that
whites are superior to blacks, and that those with brown skins
are mud people.
However, that "common sense" is obviously wrong.
