Twisted Pair (10BaseT) Ethernet

For various reasons, this is now the preferred Ethernet technology. In this system, stations are "star-wired" to a central hub, using a 4-wire variation on standard telephone cabling:
UTP Ethernet hub
The hub acts as a repeater, so whilst this superficially looks like a group of point-to-point links, all stations still "see" each other's transmissions, just the same as the bus topology. In other words, it's still a "shared medium" network.
