Real memory is, indeed, the RAM.
Virtual memory is - as the term suggests - not real! It is NOT strictly the
paging space. Rather, it is the total amount of memory allocated to a
process. Some of this might be backed by Real memory; some of it might be
on paging space. Some of it might not exist anywhere at all, except as
pointers in control blocks.
