Hear, hear, Jerry! This is how I have always heard them referred to when
I worked as a network admin. A router is a router, and a "cable modem"
may or may not (usually not!) have any routing capability. It is really
a bridge connecting two networks, as I mentioned previously. It doesn't
do any modulating or demodulating. It simply allows the packets to go
from one network to the other.
