Spanning Tree Protocol (STP) is a link management protocol that helps to prevent 
undesirable loops occur in the network. For an Ethernet network to function properly, 
only one active path can exist between two stations. If a loop exists in the network 
topology, duplication of messages will occur and this might confuse the forwarding 
algorithm and allow duplicate frames to be forwarded. 
 
In short, the main purpose of activating STP is to prevent looping when you have 
redundant paths in the network. Without activating STP, redundant topology will cause 
broadcast storming.
