I have always wanted to throw this in. We know that Unix (Linux) is a OS
that uses Virtual memory concepts. But where is the address memory that
is paged in and out of real memory. It is not in the swap partition.
swap is an old concept that implements roll in and roll out that existed
before OS were equipped with Virtual memory.

It is used too augment the processing of the Paging activities.
