What happens when a data collision occurs on an Ethernet bus?
- The CRC value is used to repair the data frames.
- All devices stop transmitting and try again later.
- The device with the lower MAC address stops transmitting to give the device with the higher MAC address priority.
- The MAC sublayer prioritizes the frame with the lower MAC address.
Explanation: Ethernet uses CSMA/CD. When a collision is detected on the media, all devices stop transmitting to allow the collision to clear. After the collision has cleared, devices will again attempt to transmit.
