a router forwards data to the relevant computer on a LAN, on a bigger
scale it can decide whether info for USA is sent via
undersea cables or satelite etc for best path for cost.
A broadband router acts as a gateway between computers on the LAN and
the rest of the world, again deciding whether traffic
should go between pc's and/or to the net.
A ADSL router does the same as a broadband one, but I think there is
mod/demod going on as data signals are encoded to a frequency to high
human ears (to get more packed in). Hence the reason for the
microfilters which stop you hearing any squeaks on you phone.
I may be partly or completely wrong on some or all points! ;-)
