Line 1: In [[computer science]] and [[information theory]], '''data differencing''' or '''differential compression''' is producing a [[technical description of the 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 ==
