Each active job has its own Page Map Table (PMT), which contains the vital information
for each page—the page number and its corresponding page frame memory address.
Actually, the PMT includes only one entry per page. The page numbers are sequential
(Page 0, Page 1, Page 2, through the last page), so it isn’t necessary to list each page
number in the PMT. The first entry in the PMT lists the page frame memory address
for Page 0, the second entry is the address for Page 1, and so on.
