When you have a device on the network, it will need to send data to other devices in the network. It can do this in three ways.

Unicast
The source device sends data packets directly to a destination individual host.

Broadcast
Sends data packets to all device on the network, DHCP protocol uses broadcast packets.

Multicast
Sends data packets to a selected group of hosts on different networks.
