Your network adapter has a setting called “duplex” that is currently set to full-duplex. What does this mean?
A) Your network card can either send or receive information at a time, but not both simultaneously
B) Your network card can send and receive information simultaneously
C) Your network card can operate at only 100 megabits per second
D) Your network card can operate at either 10 or 100 megabits per second, depending on the network configuration
The answer: B) Your network card can send and receive information simultaneously
Half-duplex networking was normal when we all shared a single media, but the introduction of switched networks brought with it the ability to have every device on the network connected at full-duplex. With full-duplex, devices can send and receive information at the same time, greatly improving the efficiency of traffic flows. With full-duplex, there’s no need to wait until the end of a transmission to begin sending traffic.
