Question

Solve each of the following questions:

a)      If the total number of frames inthe main memory are 64 and the size of each frame is 64 bits thenwhat will be the size of main memory in bytes?

b)      Calculate the size of the pagetable (in bytes) if there are 8 pages and there are 256 frames inthe main memory? (assuming that page table just contain theinformation of |f|+|d|)

c)      If 8 bits are used to representthe page number, what will be number of pages in the logicaladdress space of a process?

Explanation / Answer

Dear User,           a) Thesize of the main memory in bytes = 64 x 64 = 4096                                                                                      = 4096/8                                                                                      = 512 bytes          b) The numberof pages = 8 = 23                                       So, 3bytes            The number of frames = 256           The size of the page table in bytes = 256 * 3=768 bytes                                       So, 3bytes            The number of frames = 256           The size of the page table in bytes = 256 * 3=768 bytes                      c) Thenumber of pages in the logical address space of a process =8pages I hope this will helps toyou
