Computer Science for IGCSE & O level - Data Transmission (Section 12 - No. 8)
What is the main difference between half-duplex and full-duplex data transmission?
Half-duplex transmits data in one direction, full-duplex transmits data in two directions simultaneously.
Half-duplex transmits data in one direction at a time, full-duplex transmits data in two directions, one at a time.
They are the same.
Half-duplex uses parallel transmission, full-duplex uses serial transmission.
解释
Full-duplex allows two-way simultaneous data transfer; half-duplex requires alternating directions.
