WebApr 11, 2024 · Entropy is a concept from information theory that measures the uncertainty or randomness of a system. It can also be used to quantify the complexity and diversity of digital communication data and ... WebEntropy is a measure of the disorder of a system. Entropy also describes how much energy is not available to do work. The more disordered a system and higher the entropy, the less of a system's energy is available to do work. Although all forms of energy can be used to do work, it is not possible to use the entire available energy for work.
