Q5. describe why is segmented paging significant (as compared to the paging system)? Illustrate the various pieces of the virtual address in segmented paging system?

Q6. Assume that the two processes enter the ready queue with the given properties:

Process 1 consists of a total of 8 units of work to perform, however after every 2 units of work, it should perform 1 unit of Input-output (therefore the minimum completion time of this process is 12 units). Suppose that there is no work to be done given the last Input output operation.

Process 2 consists of a total of 20 units of work to perform. This process occurs just behind P1.

Show the resultant schedule for the shortest first job (preemptive) and the round-robin algorithms. Suppose that a time slice of 4 units of RR. Illustrate the completion time of each process under each and every algorithm?
