Difference Between Broadcast and Multicast
Broadcast | Multicast |
---|---|
It has one sender and multiple receivers. | It has one or more senders and multiple receivers. |
It sent data from one device to all the other devices in a network. | It sent data from one device to multiple devices. |
It works on star and bus topology. | It works on star, mesh, tree and hybrid topology. |
It scale well across large networks. | It does not scale well across large networks. |
Its bandwidth is wasted. | It utilizes bandwidth efficiently. |
It has one-to-all mapping. | It has one-to-many mapping. |
Hub is an example of a broadcast device. | Switch is an example of a multicast device. |
It increases network traffic because the data packets are sent to every other node in the network |
It doesn’t increase network traffic |
The message to be sent should be tripled checked as some sensitive or confidential information shouldn’t be distributed to everyone in the network |
No such issue, because the message is target to only selected people. |
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.
