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 4 2 and 5 1,3 and 4 1 and 3 2 and 4 2 and 5 1,3 and 4 1 and 3 ANSWER DOWNLOAD EXAMIANS APP

Computer Networking Ethernet networks can be cabled in a number of topologies, depending on what works best in each environment. As more nodes are added, the efficiency of Ethernet decreases. Select the best answer as to why Ethernet becomes less efficient as size increases. Cable terminators do not reflect the signal properly Network collisions occur "Line echo" occurs due to the impedance of the cable Repeaters cannot increase the signal strength sufficiently Cable terminators do not absorb the signal properly Cable terminators do not reflect the signal properly Network collisions occur "Line echo" occurs due to the impedance of the cable Repeaters cannot increase the signal strength sufficiently Cable terminators do not absorb the signal properly ANSWER DOWNLOAD EXAMIANS APP
