What does STP stand for in networking?

STP stands for Spanning Tree Protocol, which is an essential network protocol used primarily in Ethernet networks to prevent loops. In a switched network, redundant paths can create a loop, leading to broadcast storms and network instability. STP operates by identifying the topology of the network and selectively blocking certain paths while ensuring a loop-free operational environment.

Through a process of exchanging Bridge Protocol Data Units (BPDUs), STP calculates the best path for data transmission and designates a root bridge, from which all other switches' paths are determined. It effectively allows for the simultaneous use of redundant links while ensuring that only one active path is in use at any given time.

The other terms mentioned do not relate to the core functions of networking associated with loop prevention and topology management like STP does. Thus, Spanning Tree Protocol is the correct and relevant answer in the context of network technology.
