Replying to "Nuno Ferreira"
The (umm.. NETGEAR 8 Port 10/100 Mbps Ethernet) switch is something I bought 7
years ago when I first started to network my SOHO. Win 95 and 98. So I have
always felt compelled to keep it. Ethernet switches allow your Ethernet cards
to operate in Full Duplex mode. It's mainly a hub, bridge.
I use it as a uplink for others devices, workstations, servers. Keep the
work-horse off of the firewall/router, if and when I share *LARGE* files on
my LAN. Sending and receiving data at the same time, gets dedicated bandwidth
instead of shared bandwidth.
Separating systems that have sensitive data from the rest of the network
decreases the chances that people will gain access to information they are
not authorized to see.
There is something about this that eliminates the need for other workstations
attached, to examine each packet broadcast on the netwok, I think.

See Figure 2. It's like my basic SOHO.
