full-duplex communication; full-duplex transmission
Technical computing term for simultaneous two-way data transmission.
In full-duplex communication, transmission and reception can occur simultaneously.
半二重通信 is half-duplex, where communication can occur in both directions but only one direction at a time, unlike 全二重通信 which allows simultaneous two-way communication.
Compound of 全 (full), 二重 (double, duplex), and 通信 (communication). A direct calque of the English term 'full-duplex communication'.
