Star Topology is a network structure where all devices are connected to a central hub or controller. This central node manages communication and acts as the single point of control. It is simple to implement and makes troubleshooting easier, as issues are usually isolated to individual connections. However, the hub represents a single point of failure - if it goes down, the entire network stops working. Star topology is often used in small IoT setups where ease of management is more important than redundancy. It provides good performance but less fault tolerance compared to mesh topology.
