frame size = 512
page size = 512
(1)2345
page number = 2345/512 = 4
page offset = 2345 mod 512 = 297
Page-4 maps to frame number 2
Physical address = frame number * page size + page offset
Physical address = 2 * 512 + 297 = 1321
(2)1024
page number = 1024/512 = 2
page offset = 1024 mod 512 = 0
Page-2 maps to frame number 10
Physical address = frame number * page size + page offset
Physical address = 10 * 512 + 0 = 5120
(3)6780
page number = 6780/512 = 13
page offset = 6780 mod 512 = 124
There is no mapping for page-13 in page table.

Suppose that we have a computer system using 32-bit logical address and 46–bit physical address. It also uses paging for memory management with a single-level page table organization. The page size is 4K bytes and each page table entry is 32 bits or 4 bytes in size. Calculate the number of bits in each field in the logical address, the size in bytes of the page table, and the number of frames.
