  A unification of thermodynamics and information theory is proposed. It is
argued that similarly to the randomness due to collisions in thermal systems,
the quenched randomness that exists in data files in informatics systems
contributes to entropy. Therefore, it is possible to define equilibrium and to
calculate temperature for informatics systems. The obtained temperature yields
correctly the Shannon information balance in informatics systems and is
consistent with the Clausius inequality and the Carnot cycle.
