Explain What is STP?

The STP also stands for Spanning Tree Protocol constructs a loop-free logical topography for Ethernet networks. It is a network protocol. Preventing bridge loops along with the broadcast radiation that results from them are the primary functions. If an active link fails, spanning tree consequently allows a network design to include backup links so that it could provide fault tolerance.

As denoted, STP creates a kind of spanning tree within a network of connected layer-2 bridges, along with disabling those links that which doesn’t form part of the spanning tree, leaving a single active path between any two network nodes. Radia Perlman invented the algorithm on which STP is based. At that time she was working for Digital Equipment Corporation.
