Question 95/107

IP multicast effectively conserves network bandwidth and reduces network load. Therefore, it is widely used in network services, such as IPTV, real-time data transmission, and multimedia conferencing.

A. TRUE

B. FALSE

Correct Answer: A

Comprehensive and Detailed Step-by-Step Explanation:
1. Overview of IP Multicast:
* IP multicast is a method of delivering data from one source to multiple destinations simultaneously.
* Unlike unicast (one-to-one communication) or broadcast (one-to-all communication), multicast is one- to-many, allowing data to be sent only to subscribers (multicast group members).
* This significantly conserves bandwidth and reduces the load on the network because the source only sends a single stream of data, which is replicated by multicast routers as needed.
2. Use Cases for IP Multicast:
IP multicast is widely used in network services that involve real-time or large-scale data delivery, such as:
* IPTV (Internet Protocol Television): Broadcasting live TV streams.
* Real-Time Data Transmission: Delivering stock market data, sensor updates, etc.
* Multimedia Conferencing: Supporting group calls, webinars, and online meetings.
3. Why the Statement is TRUE:
* IP multicast reduces unnecessary traffic and maximizes efficiency, making it ideal for these types of network services.
