Broadcast
Broadcast transfer (one-to-all) techniques and can be classified into two types : Limited Broadcasting and direct Broadcasting. In broadcasting mode, transmission happens from one host to all the other hosts connected on the LAN. In simple words, broadcasting is a communication mechanism where data is sent to all the nodes in a network. The broadcast address is a special reserved address bits for broadcasting messages in a network, we can calculate the broadcast address given its IP address and the subnet Mask.
Devices such as bridge uses this. A protocol like ARP implements this, in order to know the MAC address for the corresponding IP address of the host machine. ARP does IP address to MAC address translation. RARP does the reverse.
Difference Between Broadcast and Multicast
The world of computer networks has a variety of communication mechanisms and protocols that provide a set of guidelines and rules to be followed while transmitting data from one node to another. These mechanisms and protocols determine the efficiency and reliability of the inter-connected and intra-connected network systems. In this article, we’ll learn about the difference between two of the most commonly used message distribution mechanisms – Broadcast and Multicast, shedding light on the unique characteristics of both.
Broadcast and a Multicast are two different communication mechanism in computer networks for transmitting data between the nodes in a network.
