Which concurrency model do multiple process/thread programming belong? : https://en.wikipedia.org/wiki/Concurrency_(computer_science)#Models says

Which model(s) do multi-process programming (as in C, Java, Python) belong to?

Which model(s) do multi-threading programming (as in C, Java, Python) belong to?

Thanks.
