Line 1: In [[computer science]] and [[information theory]], '''data differencing''' or '''differential compression''' is producing a [[difference]] between two sets of data – a source and a target. Formally, a data differencing algorithm takes as input source data and target data, and produces difference data ("differencing"), such that given the source data and the difference data, one can reconstruct the target data ("patching" the source with the difference to produce the target). == Examples ==
