7.COMMUNICATION TYPES IN NETWORKING

      

The network communication types in IPV4 there are 3 types but there is no BROADCAST in IPV6.

1.UNICAST

2.MULTICAST

3.BROADCAST

1.UNICAST

Defination: When communication is sent for  a single device is called as UNICAST communication.

Ethernet is multiaccess medium,when one device send data with only one destination address then packet will go to all device but is ment for only one device is called as UNICAST.

Unicast is a type of communication where data is sent from one computer to another computer.

UNICAST COMMUNICATION

Example:

1) Browsing a website. (Webserver is the sender and your computer is the receiver.)

2) Downloading a file from a FTP Server. (FTP Server is the sender and your computer is the receiver.)

2.MULTICAST

Defination: When packet is sent for group of device then communication is called as MULTICAST communication.

MULTICAST COMMUNICATION

Example:

when multiple clients require same data at the same instance (for example, online TV) we can use multicast instead of unicast.

3.BROADCAST

Defination: When packet is sent for all device in the network is called as BROADCAST communication.

BROADCAST COMMUNICATION

Switches by design will forward the broadcast traffic and Routers by design will drop the broadcast traffic. In other words, Routers will not allow a broadcast from one LAN to cross the Router and reach another Network Segment. The primary function of a Router is to divide a big Broadcast domain to Multiple smaller Broadcast domain.

Example: ARP Request message, DHCP DISCOVER Message
