Which type of connection allows a single node to communicate with multiple nodes?

The point-to-multipoint connection is characterized by a single node being able to communicate simultaneously with multiple nodes. This type of configuration is often used in scenarios such as wireless networks or telecommunications, where one central transmitter sends data to several receivers. The single node acts as a hub or source, while all other nodes serve as endpoints that receive the data sent from the hub.

For example, in a wireless networking environment, a router can connect multiple devices, allowing each device to receive data from the router without needing to establish individual connections for each communication. This makes point-to-multipoint connections efficient for broadcasting information to many recipients at once.

In contrast, a point-to-point connection refers to a direct link between two nodes, limiting communication to just those two. A broadcast connection typically suggests that a signal is sent out to all nodes in a network but does not imply that there is a defined structure of communication, as each node may receive the broadcast but doesn’t necessarily send back data to the sender directly. A star connection, while allowing many nodes to communicate with a central node, doesn't clearly define the ability of the central node to communicate back to all others simultaneously in the same structured manner as point-to-multipoint.
