For each of the four processes P1, P2, P3 and P4, the total size in kilobytes (KB) and
the number of segments are given below.
The page size is 1 KB. The size of an entry in the page table is 4 bytes. The size of an
entry in the segment table is 8 bytes. The maximum size of a segment is 256 KB. The
paging method for memory management uses two-level paging, and its storage
overhead is P. The storage overhead for the segmentation method is S. The storage
overhead for the segmentation and paging method is T. What is the relation among
the overheads for the different memory management methods in the concurrent
execution of the above four processes?
