    Q1
    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.

    Q2
    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.
