Yes, they're called switches.  In addition, more and more of them appearing
nowadays are auto-sensing 10/100, at least one one or two ports.

well, a FD NIC is no good without a FD hub :-)   one end FD with the other
end HD will just result in an ungodly number of collision on the HD end...

this one, OTOH, is more difficult... aside from the fact that I don't live
in the Netherlands, I haven't seen any switches with coax ports.  You could
always get an 8 port switch, and a 10bT <-> coax media converter,
though...

This is a switch I think.

Fact. It's referred to as a "switch".

Fact. This also requires a switch which supports full duplex mode. Many do
not.

Humm. I would assume somewhere???? ;)

It's not unusual to have 1 coax on a switch/hub you can use it for SNMP in

case U use Side-stream management. Otherwise if you use it for connecting
your network I don't believe it will take advantage of that FD 10mbit. And
all
data the switch doesn't know how to route will drop at that coax-line.
IMHO it's usefull for management information.

Kind regards,

This is only 10Mbps in each of two directions, which isn't as useful
as a 20Mbps "real" bandwidth IMHO.
