Questions:
In a system with 32 bit virtual addresses and 1KB page size, use of one-level page tables for virtual to physical address translation is not practical because of
|
A |
the large amount of internal fragmentation |
|
B |
the large amount of external fragmentation |
|
C |
the large memory overhead in maintaining page tables |
|
D |
the large computation overhead in the translation process |
Solution:
Option (C) is Correct.
Page size = 1KB
Virtual address = 32 bit = 232
No. of page level entries = 232 / 210
= 222
= 4M (Too large size)
