Information entropy is a concept from information theoryit tells how much information there is in an eventin general, the more uncertain or random the event is, the more information it will contain. Define energy be able to state the first and second laws of thermodynamics entropy is a measure of the degree of randomness or disorder of systems explain. The second law of thermodynamics (the entropy law or law of entropy) was formulated in the middle of the last century by clausius and thomson following carnot's earlier observation that, like the fall or flow of a stream that turns a mill wheel, it is the fall or flow of heat from higher to lower temperatures that motivates a steam engine.
