You'll likely get a lot of answers, but here is the quick one.

Twisted Pair is aka "unshielded twisted pair"....used in high
quality telephone wiring--thus its advantage.

For Ethernet, it is called 10BaseT or 802.3i.  

It is star-wired to a central smart hub.  Although the DTE's
think they are on a bus topology, these smart hubs can do a LOT
for network reliability and fault isolation.  No More BeeperNet!

With the advent of twisted pair Ethernet and the fault isolation
advantages of the accompanying smart hubs, IMHO Ethernet will do
a lot to stem the rising incidence of Token Ring in all but true
blue IBM shops....OR in situations where the deterministic
thru-put of T/R is an absolute requirement..

PLEASE NOTE that that last is a personal opinion....ONLY.
