Given your own example for segment table and logical addresses, calculate the physical addresses.

Answer

In the system of page storage management the  logical address space of  a job I 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                             3


• 2                              7


• 3                             9

What is the physical address corresponding to the valid logical address 5678?

Calculate the page number and page offset of logical address 5678

Page number: 5678/2048=2

Page offset: 5678-2048*2=1582

Query table and find the physical block corresponding to page 2

Is 7

And calculate: 2048*7+1582=15918
