In thermodynamics, computer science thermodynamics is the application of thermodynamics to the study, operation, modeling, and design of computer systems. A closely related filed is information theory, which relies on Shannon entropy to study information.

The first formal connection between thermodynamics and computation was made by Hungarian-born American chemical engineer John von Neumann who in a 1949 lecture asserted that any computer operating at a temperature T must dissipate at least kT ln 2 unit of energy, approximately 3E-21 joules at room temperature, “per elementary act of information, that is per elementary decision of a two-way alternative and per elementary transmittal of one unit of information.” [1]
