What is broadcast communication?

Broadcast communication refers to the process of transmitting a message from a single sender to multiple receivers simultaneously. It is commonly used in scenarios where information needs to be disseminated to a large audience, such as in radio or television broadcasts, public announcements, or certain types of network communications.

In computer networks, broadcast communication means sending a message to all devices within a specific network or subnet. All devices on the network receive the message, even if only some are intended to act on it. This is in contrast to unicast (sending a message to a single recipient) or multicast (sending a message to a specific group of recipients).

Broadcast communication is efficient for disseminating information quickly but can lead to unnecessary network traffic if used excessively.
