In the system of page storage management, the logical address space of a job J is 4 pages (2048 bytes per page), and the known page image table (page table) of the job is as follows:
Page number     block number
0                                    2
1                                     4
2                                    6
3                                    8
What is the physical address corresponding to the valid logical address 4865 in decimal system.

Solution:
The page number and page offset of logical address 4865:
page number: 4865/2048 = 2
page offset: 4865 - 2048*2 = 769
We can know the block number according to the page number 2 is 6.
physical address : 2048*6 + 769 = 13057
