full-duplex

Both directions simultaneously

Full-duplex describes a communication system where data can flow in both directions simultaneously.

A telephone conversation is full-duplex—both parties can speak and hear at the same time.

This contrasts with half-duplex systems like walkie-talkies, where only one side can transmit at a time: The network switch supports full-duplex connections.
