Comment on "Entropy Generation in Computation and the Second law of Thermodynamics", by S. Ishioka and N. Fuchikami

This brief note argues that, contrary to the claim of Ishioka and Fuchikami (chao-dyn/9902012), Landauer's principle is concerned a priori with entropy generation in computing processes. The concept of heat, in this principle, is only relevant when a connection with thermodynamics is established.
