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. 1 and 3 2 and 5 1,3 and 4 2 and 4 1 and 3 2 and 5 1,3 and 4 2 and 4 ANSWER DOWNLOAD EXAMIANS APP
Computer Networking Which statement is true regarding classless routing protocols?1. The use of discontiguous networks is not allowed.2. The use of variable length subnet masks is permitted.3.
