What method is used to manage contention-based access on a wireless network?
- CSMA/CD
- priority ordering
- CSMA/CA
- token passing
| Explanation & Hint:
The method used to manage contention-based access on a wireless network is CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance). Unlike Ethernet networks that use CSMA/CD (Carrier Sense Multiple Access with Collision Detection), wireless networks cannot reliably detect collisions due to the “hidden node problem.” Therefore, they use a method to avoid collisions before they happen, which is what CSMA/CA is designed to do. |
