Which type of network topology is commonly used for video distribution in VDV systems?

• A. Star topology
• B. Ring topology
• C. Bus topology
• D. Mesh topology

Answer: (A)

Star topology is commonly used for video distribution in Voice-Data-Video (VDV) systems due to its advantages in scalability and performance. In a star configuration, all devices are connected to a central hub or switch. This design allows each device to communicate directly with the hub, which simplifies the process of managing data traffic. For video distribution, the central hub can efficiently manage multiple video streams, ensuring that bandwidth is utilized effectively and reducing the likelihood of data collisions. Since video data requires significant bandwidth to maintain quality, having a central point for distribution helps streamline the delivery process. Additionally, the star topology makes it easier to add or remove devices without disrupting the entire network, which is beneficial in dynamic environments where new video sources or displays may need to be integrated. In contrast, other topologies like ring or bus can introduce complexities and limitations when handling high-bandwidth applications like video.
