Unicast communication

Unicast communication
The unicast process occurs between two hosts only. A single destination address is used to
ensure that data is sent to only one host. This could be client-to-server, server-to-client, or peerto-
peer. It doesn’t matter, so long as the frames are addressed to a unicast address. So when one
host wants to send data to multiple hosts or to all the hosts on the same network segment, things
have to change. That is where multicast and broadcast communication comes in.
