Memory Management Worksheet

Explain the difference between internal and external fragmentation.

$2\mathrm{.}4$ On a system with paging, a process cannot access memory that it does not own. Why?

Consider a simple paging system with the following parameters: $2^{32}$ bytes of physical memory; page size of $2^{10}$ bytes; $2^{16}$ pages of logical address space.

a$)$ How many bits are in a logical address?

b$)$ How many bytes are in a frame?

c$)$ How many bits in the physical address specify the frame?

d$)$ How many entries in the page table?

For each of the following decimal logical addresses, compute the page number and the offset given a $4-$KB page size and an $8-$KB page size: $24000$ and $32850$
