What do you meant by Multicast ?

Hi everyone, on today we are going to learn about multicast in simple definition to understand easily.

Multicast is a communication method and data delivery scheme in which a single source sends the same data to multiple receivers simultaneously.

In simple points to remember we can say as;

• The multicast process involves a single sender and multiple receivers.
• User datagram protocol (UDP) is the most common protocol used with multicasting.
• Multicast is one of the packet types in the (Internet Protocol version 6) IPv6. 

Examples: 

1. Email is the best example of multicast, where a user can choose to send mail to many different addresses, rather than a complete contact list. 
2. Another example is the one-to-many multicasting of a streaming video toward many users from a single server. 
3. Another good example is Internet protocol (IP) multicasting, where network nodes, like switches and routers, handle data packet replication through multicast groups.
