Q: Consider a system which has Logical Address = 4 GB, Physical Address PA= 64 MB, Page Size = 4 KB, then calculate Number of pages =? Number of frames =? Number of entries in Page Table =? Size of Page Table =?
This question was already asked on Bartleby however the two level table was not created. A computer system uses 16-bit addresses for virtual and physical addresses, and each page and frame has a size of 256 bytes. 1. suppose that the OS uses a two-level page table. Draw the page table using the same structure and logic as the image provided, from an article found online this logic can be anazyed through the link https://sonsh0824.tistory.com/entry/MultiLevel-Page-Table . (Assume that frames 7 through 221 are free, so you can allocate space for the page table there.) In addition, suppose that the page-table directory storage comprises a whole number of consecutive full frames. (For examples: if the directory entry is 2 bytes, the entry’s storage comprises 1 frame; if the directory entry is 260 bytes, the entry’s storage comprises 2 consecutive frames.) 2. What is the size of the two-level page table given in question I(f)? 3. Now, translate the virtual addresses to physical…
