The latter is a general term for the whole procedure, and DNA extraction is just one part of it. To put it simply, it is the methodology used to isolate and purify the DNA in a sample. In the isolation process, there may be a tad of contamination. In contrast, extraction decontaminates the DNA with some physical or chemical methods.
