the building in question is 3 networks. One is the Point of sale
network where i don't want any slowdown. The second floor is the
office/acct computers. The third floor are packaging appliances where
network speed isn't important since the network access is only needed
to update their individual databases.
But i rather just have gigabit ethernet all over the place. using hub/
switch/bridge to segment the 3 places (depending on what's cheaper,
how many ports i need, etc.)
but since i'm lazy i just want to serially connect the 3 computers in
the office together. I've read somewhere that i need a terminator plug
at the end of the cat5. so it's one line to the hub, have that
connected to a wallplate, then use another line to connect a second
wallplate to the first wallplate. Bus network eh.
