On a point-to-point network, which communication type is used when two devices can both transmit and receive but not at the same time?

• controlled access
• deterministic
• full-duplex
• half-duplex

Explanation: 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. Half-duplex communication is typically contention-based, whereas controlled (deterministic) access is applied in technologies where devices take turns to access the medium.
