The overall entropy of a system may only ever increase or stay constant during spontaneous processes, according to the second law of thermodynamics.
What is the second law of motion?According to the second rule of thermodynamics, entropy does not decrease in a closed system.
In other words, if the system is originally in an ordered, low-entropy state, its condition will tend to naturally drift toward a maximum-entropy state (disorder).
Therefore, the second law of thermodynamics states that the total entropy of a system may only ever increase or remain constant during spontaneous processes.

During the process of convergence, STP goes through several port states, including listening, learning, blocking, and forwarding. Once STP has completed convergence, the port states will either be in a blocking state or a forwarding state.
In the blocking state, the port will not forward any frames and will only listen for BPDUs (Bridge Protocol Data Units). In the forwarding state, the port will forward frames and also listen for BPDUs. These two states are considered stable because they do not change unless there is a change in the network topology.
