Reversible computing is a computational paradigm that allows computations to be run in both forward and reverse directions. In other words, it enables the reconstruction of input data from the output without any loss of information. This property contrasts with conventional (irreversible) computing, where information is often lost during operations (e.g., through processes like erasure of bits), which is linked to energy dissipation and entropy increase according to the second law of thermodynamics.
