Which of the following best explains the function of a network switch?

The function of a network switch is to forward data only to the desired recipient, making it a crucial component in data networks. When data packets arrive at a switch, it examines the destination address of each packet and then sends that packet to the appropriate port that connects to the intended device. This targeted approach reduces unnecessary traffic on the network, allowing for more efficient communication and improved performance.

A switch operates at the data link layer (Layer 2) of the OSI model, maintaining a MAC address table that helps it learn which devices are connected to which ports. This capability enables it to deliver data specifically to the right location instead of broadcasting it to all connected devices, as would be the case with a hub. This specificity is especially important in environments with many connected devices, such as in audio networks utilizing technologies like DANTE, ensuring that audio data flows seamlessly without collision or interruption.
