That's probably because sometime they are both. My modem (the one
supplied to me by my ISP) is also a router. It's an Actiontec GT701-WG,
"DSL Modem with Wireless Gateway." Sometimes an ISP sends you a modem
that is just a modem and nothing more.

I bought one of these because my modem/router has has only one ethernet
port. I wanted to connect two computers to the internet, and I didn't
want to use wireless and I didn't want to use one of my machines as a
gateway for the other. The switch sits between my modem/router and each
computer -- that is, the ethernet for each computer is connected to the
switch, and the ethernet for the switch is connected to the
modem/router. I could have bought a hub instead of a switch, but
there's very little price difference and a switch seemed like the better
buy. In this way, each computer can reach the internet independently of
the other through my ISP assigned IP address, and each computer has it's
own internal IP address (192.168.0.2 and 192.168.0.3), so I can transfer
files between them easily.

If my modem had been "just a modem" and not a modem/router, I would have
bought a router instead of a switch, and done the same thing I'm doing
now.

I'm not sure why you would need one of these?

I think maybe you are confusing a "bridge" with "bridged mode." Many
(most? all?) routers can be configured to operate in "bridged mode" if
you want or need that. Otherwise, they operate in "router mode." In
bridged mode, you would need a PPPoE (or PPPoA) client on your machine
to login in order to connect. In router mode, your router is the bridge
between you and your ISP.
