Ye kin lectures men se he reference lecture please

its from lecture no. 32 and 33

Can you please mention formulas you used?

      no. of pages = 4

  1. Number of bits required for pages  = 2 

no. of memory frames= 16

no. of bits required for frames = 4

 The corresponding physical address (f , d) = (2 , 3) = 0010 011

The corresponding physical address (f , d) = (3 , 6) = 0011 110

REMEMBER ME IN PRAYERS STUDENTS

5) ka b answer bata dein please

How you find out the physical address

kindly explain ...

Doa cs 604 assignment solution pllzzzz

 

after calculating the no. of bits using formula p =ceiling[log2 4]

d= ceiling[log2 8]

f= ceiling[log2 16]

address are calculated using page table and appending the offset

how you find out the number of pages?

Ceiling ka kea mean he?
