http://www-2.cs.cmu.edu/afs/cs/academic/class/15213-f02/lectures/class28.pdf contains a good description of what is thread-based, what is process-based. And the "whys" and "hows" of one or the other.

Some operating systems are traditionally stronger at handling multiple processes. Others are stronger at handling multiple threads within a process. Oracle simply uses one or the other technology depending on which OS it is running on and how realtively efficient each is.
