Swapping occurs when whole process is transferred to disk,
while paging is when some part of process is transferred to
disk while rest is still in physical memory. There are two
utilities to monitor memory, called vmstat (for bsd, etc),
sar( for system V, etc). Page-ins and page-outs are pages
moved in and out from physical memory to disk, swap-ins and
swap-outs are processes moved in and out of disk.
