Multicast
Multicast is a network communication method where data is sent from one sender to multiple receivers simultaneously, using a single transmission over the network. It efficiently distributes data to a group of interested devices, reducing bandwidth usage compared to unicast (one-to-one) or broadcast (one-to-all) methods. This is commonly used for streaming media, online gaming, and software updates across networks.
Developers should learn multicast for applications requiring efficient one-to-many data distribution, such as live video streaming, IPTV, or real-time multiplayer games, where minimizing network load is critical. It's essential in network programming, IoT systems, and distributed computing to optimize resource usage and ensure scalability in large-scale deployments.
