you need to implement stp when you are having multiple or you can say redundent connectivity with other switch.
spanning tree is used to prvent the loop in the swithcing network. It will elect the root bridge from the whole switch network. Root bridge is elected using lower priority and lowest MAC address..which is known as the Bridge ID. It means switch with the lowest bridgeID will become a root bridge. and then it will elect the root port as well as designeted port and put some port in blocking state so that loop will not occur.
Paths through a network all relate back to the Message Priority Vetor [Bytes 6 - 27 of the actual BPDU, so starting with the 23rd bytes of the ethernet frame].
The Root Path cost [Bytes 14 to 17 of the actual BPDU] shows the "rolled-up" cost back to the Root Bridge and a switch will select the lowest cost back to the root Bridge when selecting it's root port.
