Question

Mark each statement as T (true) or F (false), or fill in the blank. Logical addresses are the same as virtual addresses. Virtual addresses are the same as physical addresses. Suppose that memory holes are sized 4, 6, and 8 (in order). Then the worst-fit allocation for a request of size 3 is: For a given system, all pages are the same size. Suppose a system has 32 pages. The required number of bits for page number is: For the above system, first page number is: For the above system, last page number is: There is a single master page table for all processes in an OS. Suppose a process is allocated 100 units of memory. It uses 80 units of memory. Then the internal fragmentation is: Page tables translate: to. (Please turn over)

Explanation / Answer

1) FALSE (can be true only x86 architecture chips)

2) FALSE

3)worst fit of size 3 allocation is 8 because in worst fit , we allocate the largest to satisfy the request

4)TRUE

5)32 pages representation is required . Therefore , the no of bits required is 5

i.e 2^5 = 32

6) PAge number = 00000

7)page number = 11111

8) TRUE
