Which local area network topology is represented?

1. star

2. ring

3. common carrier

4. bus

The correct answer is: star

The local area network topology represented in this question is a star topology, which is characterized by a central hub or switch that connects all network devices. In a star topology, each device is connected to the central node independently, allowing for easy troubleshooting and management since each connection can be monitored individually. This structure also enhances performance because devices communicate primarily through the central hub, minimizing data collisions that can occur in other topologies. The star topology is well-regarded for its scalability and flexibility; additional devices can be added to the network without disrupting existing connections. In a scenario where one device fails or requires maintenance, the rest of the network remains operational, ensuring continuous communication among other devices. This resilience is a significant advantage over other topologies, such as ring or bus topologies, where the failure of a single connection can bring down the entire network. Understanding this topology is critical for AV professionals, as many modern systems are designed with a star configuration to maximize efficiency and reliability in data communication processes.
