10baset
The 10BaseT Ethernet architecture runs at 10 Mbps and uses baseband transmission.
It uses a star topology with a hub or switch at the center, allowing all systems
to connect to one another. The cable it uses is CAT 3 UTP, which is the UTP
cable type that runs at 10 Mbps. Keep in mind that most cable types are backward
compatible, so you could have CAT 5 UTP cabling in a 10BaseT environment. But
because the network cards and hubs are running at 10 Mbps, that is the maximum
transfer speed you will get, even though the cable supports more. Like all Ethernet
environments, 10BaseT uses CSMA/CD as the access method.
