Two stations on the Ezonexam LAN transmit at the same time, resulting in a collision. What happens when a collision occurs on the network? (Choose all that apply)
选项
A、Each device on the Ethernet segment stops transmitting for a short time.
B、A jam signal informs all devices that a collision occurred.
C、When data transmission resumes, the devices that were involved in the collision have priority to transmit.
D、The devices that are involved in the collision stops transmitting for a short time.
E、The collision invokes a random back-off algorithm.
答案
B,D,E
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.
Incorrect Answers:
A. Only the stations involved in the collision stop transmitting for a short time, not all stations on the LAN.
C. No priority is given to any stations once a collision has occurred.
