Which access method is used in IEEE 802.11 networks?

A.
Token passing

B.
Half duplex

C.
CSMA / CA (Carrier Sense Multiple Access / Collision Avoidance)

D.
CSMA / CD (Carrier Sense Multiple Access / Collision Detection)

Explanation:
IEEE 802.11 is Wireless Ethernet which uses CSMA / CA (Carrier Sense Multiple Access /
Collision Avoidance).
Incorrect Answers:
A: Token passing occurs in Token Bus and Token Ring.
B: Full duplex describes a transmission characteristic in which data can be transmitted in both
directs simultaneously. This is not an access method.
D: Ethernet uses CSMA / CD (Carrier Sense Multiple Access / Collision
Detection).Reference:David Groth and Toby Skandier, Network+ Study Guide (4th Edition),
