How does a host on an Ethernet LAN know when to transmit after a collision has occurred? In a CSMA/CD collision domain, multiple stations can successfully transmit data simultaneously. In a CSMA/CD collision domain, stations must wait until the media is not in use before transmitting. You can improve the CSMA/CD network by adding more hubs. After a collision, the station that detected the collision has first priority to resend the lost data. After a collision, all stations run a random backoff algorithm. When the backoff delay period has expired, all stations have equal priority to transmit data.
