Which type of network topology is the most common?

The star topology is the most common network configuration used today due to its centralized nature. In a star topology, all devices are connected to a central hub or switch. This design allows for easier troubleshooting, as a failure in one connection does not affect the rest of the network; only that specific device would be disconnected. It also simplifies the process of adding or removing devices without disrupting the network.

Additionally, the star topology scales well; as network demands grow, more devices can be added without significant changes to the existing structure. The central hub can also manage traffic effectively, enhancing performance compared to other topologies. This combination of reliability, ease of management, and scalability makes the star topology the most prevalent choice in modern networks, particularly in home and business environments.
