Which channel access method is traditionally associated with classic shared Ethernet networks?

Options

  • A. CSMA/CD
  • B. CSMA/CA
  • C. Token Passing
  • D. Polling
  • E. None of the above

Correct Answer (Detailed Explanation is Below)

A. CSMA/CD

Detailed Explanation

Correct Answer: CSMA/CD

  • CSMA/CD stands for Carrier Sense Multiple Access with Collision Detection.
  • It was traditionally used in shared, half-duplex Ethernet networks.
  • Devices listen to the medium before transmitting.
  • If a collision occurs, devices stop transmitting and retry after a random backoff period.
  • Modern switched full-duplex Ethernet does not use CSMA/CD.
