F. The hosts will do nothing, as the higher layers are responsible for data error correction and re-transmission.


正确答案：C
C 解析：Explanation:
When a host on an Ethernet LAN has information to send, the following steps are taken:
1. A device with a frame. to send listens until Ethernet is not busy.
2. When the Ethernet is not busy, the sender begins sending the frame.
3. The sender listens to make sure that no collision occurred.
4. Once the senders hear the collision, they each send a jamming signal, to ensure that all stations recognize the collision.
5. After the jamming is complete, each sender randomizes a timer and waits that long.
6. When each timer expires, the process starts over with step 1.
