Hi everyone,
can anyone plz help me in solving the below questions, it's from modern operating system(2nd edition) book by Tanenbaum

4.7. For each of the following virtual address, compute the virtual page number and offset for a 4-KB page and for an 8 KB: 20000, 32768, 60000.

6.21. Free disk space can be kept track of using a free list or bitmap. Disk addresses require D bits. For a disk with blocks, F of which are free, state the condition under which the free list uses less space than the bitmap. For D having the value 16 bits, express your answer as a percentage of the disk space that must be free.
