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.
