What is stp meaning?

STP stands for Spanning Tree Protocol. It is a network protocol that prevents loops in local area networks (LAN) by creating a single path between network nodes. The protocol works by automatically detecting and blocking any redundant paths between network switches, thereby ensuring that data is transmitted over a single path. This helps prevent network congestion and ensures reliable network performance. STP is widely used in Ethernet networks, especially in larger corporate networks where multiple switches are used to connect different LAN segments.
