lecture 10 : IP Addressing II
There are three types of Addressing in communication:

Unicast communication
Broadcast communication
Multicast communication
In an IPv4 network, the hosts can communicate in one of three different ways:

Unicast communication: The process of sending a packet from one host to an individual host.

Broadcast communication: The process of sending a packet from one host to all hosts in the network.

Multicast communication: The process of sending a packet from one host to a selected group of hosts.
The most common type of communication is unicast.
This is the normal host-to-host communication in both a client/server and a peer-to-peer network.
For unicast communication, the host addresses assigned to the two end devices are used as the source and destination IPv4 addresses.
During the encapsulation process, the source host places its IPv4 address in the unicast packet header as the source host address and the IPv4 address of the destination host in the packet header as the destination address.
