Ethernet (802.3) vs Token-Ring (802.5)

• Physical Layer

  • Ethernet primarily uses UTP wiring
  • Token-Ring Networks primarily use shielded twisted pair (STP) wiring

• Topology (Layout) of the Wiring

  • Ethernet always uses bus (broadcast) topology
  • Token-Ring always uses a ring topology (connectivity)

• Access Control

  • (Control of When Stations May Transmit)
  • Ethernet always uses CSMA/CD
  • Token-Ring always uses token passing
