I want to know the answer to the following question:
What is made up of producing a difference given a source and a target?
All the background I'm provided with is that "Data compression can be viewed as a special case of data differencing: Data differencing consists of producing a difference given a source and a target, with patching producing a target given a source and a difference, while data compression consists of producing a compressed file given a target, and decompression consists of producing a target given only a compressed file.". Is that enough to answer the question?
Answer: yes
