- Ethernet 10BaseT or 100BaseTX
- Unshielded twisted pair (UTP) cable
- RJ-45 connectors
- Star topology – hosts connected by hub
- MDI (NIC) vs. MDI-X (hub)
- The ends of a BaseT connection are different (one is sending, one
receiving on a pair of wires)
- To connect 2 hosts or 2 hubs you need a crossover (just like using a
null modem cable for serial ports)
