Re: Max Devices on ethernet adapters

Hubs purpose is to regenerate and re-times network signals and cannot make 
any decisions. Also a hub is one giant collision domain. A switch is a 
Layer 2 device  and make their decision based on MAC address and Hubs do 
not.  A Switch will send the data to the correct port that the host is 
connected to. A Hub sends it to every port. You are starting to see Layer 
3 switches coming into play that allow decisions based on a network 
address.

Okey Dokey... (I understand the "depends" concept very well)

You said Hubs will kill you ... Why ???

If a hub will kill you, how come a switch won't ???

By the way, I don't think processor speed has much to
do with the ethernet speed issues but that's just me.
Any processor worth it's salt in the last 8 years could
handle a billion ethernet requests standing on it's head.

Full Duplex according to all the books I have ever seen or
read requires 4 wires. Don't most garden variety ethernet
wiring setups use 2 wires ???

If you were doing a BRAND NEW installation today
and there no existing network wires, what would you
have on the back of the box and all points forward for
the connections ???

I make it easy...(810  with 100 devices 80 pc's 20 printers
all ethernet attached. All in the same building. To make it
interesting, 5 of the printers are 1000lpm and are used 70%
of the day.

To make it more interesting, NO tech people ever at this site.

(this is just for fun so don't take this serious)
