Computer Networking How does a host on an Ethernet LAN know when to transmit after a collision has occurred?1. In a CSMA/CD collision domain, multiple stations can successfully transmit data simultaneously.2. In a CSMA/CD collision domain, stations must wait until the media is not in use before transmitting.3. You can improve the CSMA/CD network by adding more hubs.4. After a collision, the station that detected the collision has first priority to resend the lost data.5. 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. 2 and 5 1,3 and 4 1 and 3 2 and 4 2 and 5 1,3 and 4 1 and 3 2 and 4 ANSWER DOWNLOAD EXAMIANS APP
