Computer Networks · Question 11 · Medium
CSMA/CD (Carrier Sense Multiple Access with Collision Detection) is the medium-access method of:
- Classic wired Ethernet (IEEE 802.3)
- Wi-Fi (IEEE 802.11)
- Token Ring
- Bluetooth
Answer and explanation
Answer: A. Classic wired Ethernet (IEEE 802.3)
Explanation: Classic shared-medium Ethernet uses CSMA/CD. Wi-Fi uses CSMA/CA (collision avoidance), because a wireless station cannot reliably detect collisions while it is transmitting.
