3. Suppose the page size in a paging system is 512 bytes.

(a) If most of the files are large—that is, much greater than 512 bytes—what do you suppose is the average internal fragmentation

(in bytes of unused space) for each file? Explain your reasoning.

(b) How would your answer to part

(a) change if most of the files were much smaller than 512 bytes?

(c) How would your answer to part

(b) change if you expressed the fragmentation in terms of the percentage of unused space instead of the number of unused bytes?
