The organizationally unique identifier (OUI) is assigned by the IEEE to an organization

address also comprised of 24 bits, or 3 bytes, that’s supposedly unique to each and
every adapter it manufactures.

_____________on an Ethernet network is the retransmission delay that’s enforced when
a collision occurs.

Back 2

Back-off on an Ethernet network is the retransmission delay that’s enforced when
a collision occurs. When that happens, a host will only resume transmission after the
forced time delay has expired. Keep in mind that after the backoff has elapsed, all
stations have equal priority to transmit data.

_____________on an Ethernet network is the retransmission delay that’s enforced when
a collision occurs.

Back 3

When using a hub all ports are in the same collision domain which will introduce
collisions as shown between devices connected to the same hub.
