Whis is black holes entropy
Beckenstein said that: the total generalized entropy never decreases. Beckenstein gave the generalized second law, that always holds: in any process, the total generalized entropy never decreases. The Beckenstein-Hawking entropy or black hole entropy is the amount of entropy that must be assigned to a black hole in order for it to follow the laws of thermodynamics as they are understood by the observers external to the black hole.
The Beckenstein bound says that the maximum possible entropy of a black hole is S = A/4, where A is the two-dimensional area of the black hole's event horizon in units of the Planck's area.
