6 Questions
Why do wireless LANs and wired LANs use different protocols for medium access control?
In a wireless LAN, frames may not reach all devices connected to the LAN.
Why is CSMA/CD not preferred for wireless networks?
It is not a secure protocol that encrypts communication.
What makes the usage of a 'random access' protocol challenging in wireless communication?
The radio spectrum is a limited resource regulated by authorities.
Why can't collisions be allowed to happen on a wireless network?
Collisions may result in data loss and network congestion.
What factor determines the choice of MAC protocol for wired LANs and wireless LANs?
The properties and characteristics of the medium used for communication.
How does the limited radio spectrum impact the choice of MAC protocols in wireless networks?
It restricts the use of protocols based on 'random access'.
Explore the differences between wireless local area networks (LANs) and wired LANs in terms of medium access control (MAC) protocols. Learn why separate MAC protocols, like CSMA/CA for WiFi and CSMA/CD for Ethernet, are used for wireless and wired networks respectively.
