When you compare the differences between half-duplex and full-duplex Ethernet, which of the following characteristics are exclusive to half-duplex? (Select two answer choices)
选项
A、Half-duplex Ethernet operates in a shared collision domain.
B、Half-duplex Ethernet operates in an exclusive broadcast domain.
C、Half-duplex Ethernet has efficient throughput.
D、Half-duplex Ethernet has lower effective throughput.
E、Half-duplex Ethernet operates in an exclusive collision domain.
答案
A,D
解析
Explanation:
A single device could not be sending a frame and receiving a frame at the same time because it would mean that a collision was occurring. So, devices simply chose not to send a frame while receiving a frame. That logic is called half-duplex logic.
Ethernet switches allow multiple frames to be sent over different ports at the same time. Additionally, if only one device is connected to a switch port, there is never a possibility that a collision could occur. So, LAN switches with only one device cabled to each port of the switch allow the use of full-duplex operation. Full duplex means that an Ethernet card can send and receive concurrently.
Incorrect Answers:
B. Full duplex effectively doubles the throughput of half-duplex operation, because data can be both sent and received at the full 10/100 speed.
C, E. In half duplex operation, the network is shared between all devices in the collision domain.
