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.

These addresses are meant for nonrouting purposes, but they are almost globally unique so it is unlikely they will have an address overlap.
These are like private addresses in IPv4 in that they are not meant to be routed.
Packets addressed to a unicast address are delivered to a single interface.
