1: Pure Swapping is the procedure of copying an entire process from main memory to secondary storage. What are the advantages and disadvantages for using demand paging over pure swapping? (Hint: page-replacement is used in both demand paging and pure swapping, one is more specific in purpose.)

2:

Only when a forked process actually writes to the memory,, a new private copy is created that is not visible to other processes. Give an example, with respect to operating systems system calls, of Copy-On-Write!
