8-Types Of Communications.

In an IPv4 Network , The hosts can communicate one of three different ways.


(1)Uni-cast Communication 
(2)Broadcast Communication
(3)Multicast Communication 

Uni-cast Communication :

This types of communication represents a single LAN interface, It means . A uni-cast frame will be sent to a specific destination address only , It does not send anything  a group of devices on the network.

(2)Broadcast Communication:

This types of communication represents all device on the LAN.A broadcast  Frames sent to a broadcast address will be delivered to all devices on the network .

If you will talk about switch network then , The broadcast address has the value of FFFF.FFFF.FFFF (all binary ones). The switch will flood broadcast frames out all ports except the port that it was received on.

(3)Multicast Communication :

This types of communication represents a group of devices in a LAN. A multicast frame sent to a multicast address will be forwarded to a group of devices in the network .
