half-duplex
Talk, then listen
Half-duplex describes a communication channel that transmits in both directions but only one direction at a time.
Walkie-talkies are half-duplex—one person talks while the other listens, then they switch.
Contrast with full-duplex, where both parties can transmit simultaneously, as in a telephone conversation.
