Which statement about half-duplex and full-duplex communication is true?

  • Gigabit Ethernet and 10 Gb/s NICs can operate in full-duplex or half-duplex.
  • Full-duplex communication is bidirectional.
  • Half-duplex communication allows both ends to transmit and receive simultaneously.
  • Half-duplex communication is unidirectional, or one direction at a time.

Explanation: Full-duplex communication allows both ends to transmit and receive simultaneously, offering 100 percent efficiency in both directions for a 200 percent potential use of stated bandwidth. Half-duplex communication is unidirectional, or one direction at a time. Gigabit Ethernet and 10 Gbps NICs require full- duplex to operate and do not support half-duplex operation.
