What is the main advantage of a star topology in network structures?

• A. It has lower installation costs
• B. It enhances fault tolerance
• C. It simplifies data routing
• D. It requires less cabling

Answer: (B)

The main advantage of a star topology is its enhanced fault tolerance. In a star network, all devices are connected to a central hub or switch. If one of the connections or devices fails, it does not affect the rest of the network. Other devices can continue to communicate with each other through the hub, ensuring that the entire network does not go down due to a single point of failure. This design significantly improves reliability and simplifies troubleshooting, as technicians can easily identify and isolate issues to specific segments without affecting overall network functionality. In contrast, other network topologies may not provide such robust isolation from failures, making star topology particularly advantageous in environments where network uptime and stability are critical.
