Question

In ITEx a host is transmitting a unicast. Which host or hosts will receive it?

a) All hosts on the network.
b) Only the destination host.
c) The source host.
d) All hosts except the destination host.

Answer 1

Only the destination host will receive a unicast transmission in ITEx, as it is a one-to-one form of communication in networking.

Step-by-step explanation:

When a host transmits a unicast in ITEx, the message is intended for one specific recipient. Therefore, the correct answer is b) Only the destination host will receive this unicast message. A unicast is a direct transmission from one source to one receiver, making it distinct from broadcasts that are sent to all network devices or multicasts that are sent to a group of subscribers.
