How does IP multicast traffic differ from IP broadcast traffic?

Multicast traffic is distinct because it specifically targets selected modem addresses rather than sending data to all devices on the network. This selective distribution allows for more efficient use of bandwidth as it ensures that only those devices that are interested in receiving the multicast data acknowledge it. In contrast, broadcast traffic sends the same data to every device on a network segment, resulting in all devices processing the incoming data, irrespective of their interest.

This targeted approach of multicast reduces unnecessary network load, which is beneficial in scenarios where data, such as streaming video or real-time applications, is meant for a particular group of users. By employing multicast, network performance is optimized because bandwidth is conserved, and the network is not overwhelmed by irrelevant data for those users not part of the multicast group.

In contrast, the other options present misconceptions about multicast and broadcast traffic. For instance, suggesting that multicast traffic is sent to all modems misrepresents the nature of multicast delivery. The idea that broadcast traffic is more efficient fails to recognize that it can actually lead to congestion, particularly in larger networks, as it requires all devices to process unwanted data. Lastly, the assertion that multicast traffic has no impact on network performance ignores the fundamental principle that while multicast is generally more efficient than broadcast, it
