Which media communication type does not require media arbitration in the data link layer?
- deterministic
- half-duplex
- full-duplex
- controlled access
Answers Explanation & Hints: Half-duplex communication occurs when both devices can both transmit and receive on the medium but cannot do so simultaneously. Full-duplex communication occurs when both devices can transmit and receive on the medium at the same time and therefore does not require media arbitration. Half-duplex communication is typically contention-based, whereas controlled (deterministic) access is applied in technologies where devices take turns to access the medium.
