Unicast, Multicast, Broadcast. What Does It Mean?

Unicast, Multicast, and Broadcast are different network transmission methods.

Unicast transmission

Unicast is a transmission between a single sender and a single receiver identified by a unique address over a network.

Multiple unicast transmissions

For video, even though multiple client computers might request the same video at the same time, a separate unicast data stream is transmitted to each client computer.

Multicast transmission

Multicast is a transmission between a single sender and multiple receivers simultaneously. The clients that receive the multicast may have a common set of criteria, or be specifically set up as a multicast group. A special kind of multicast, referred to as "anycast" is a communication between any sender and the nearest receivers in a network.

Broadcast transmission

Broadcast is a transmission from a single sender to all clients on the network. Routers can be used to divide a network into separate broadcast domains. A broadcast is then limited to a broadcast domain. The IP address indicates a broadcast, and this address is never forwarded by routers.
