Multicast

Multicast is a method of communication where one sender transmits data to multiple specific recipients simultaneously over a network. Instead of sending individual copies to each recipient (unicast) or broadcasting to everyone (broadcast), multicast efficiently delivers information to a selected group. Think of it like a radio broadcast: all listeners tuning into the same station receive the message at the same time. This approach reduces network load and speeds up data delivery, making it ideal for applications like live streaming, online conferences, or software updates shared across many devices.
