Spanning Tree Protocol (STP)

Spanning Tree Protocol (STP) is a networking method used to prevent loops in computer networks, especially those involving switches. When multiple pathways connect switches, data can circulate endlessly, causing network congestion. STP works by designating a single, optimal path for data to travel while blocking any additional routes that could create loops. If the primary path fails, STP can quickly reactivate a blocked path to ensure continuous network communication. This helps maintain a stable and efficient network, allowing devices to communicate without interruptions.
