a) Draw the GANTT chart for the Round Robin time quantum -5) scheduling algorithm. Use the same
implementation you used for the programming assignmenti.e. the processes should always run in PID order.
Assume there is no context-switch overhead. Show your work for partial credit.
b) Write your answer to the following performance metrics given your above CANTT charts. Show your work
for partial credit.
Average Response time:
Average Wating time:
Average Turnaround time:
Consider a file currently consisting of 10 blocks. Assume that the file control block and the new block
information to be added are already in memory. Calculate how many disk I/O operations are required for the
linked allocation strategy, if, for one block, the following conditions hold:
HINTS: 1) ignore disk I/O associated with the file control block. 2) each read and each write is an explicit disk
I/O. 3) assume a pointer to the end of the list for linked allocation
a. The block is added at the beginning.
b. The block is added in the middle.
c. The block is added at the end.
d. The block is removed from the beginning.
e. The block is removed from the middle.
f. The block is removed from the end.

For simplicity, assume that processes never block on any event and simply switch between the CPU and the ready queue. Also, assume that a process is still in the ready queue while a context switch is happening. a) What happens if Q is much smaller than S? What happens when Q→→ ∞, i.e. is much larger than the maximum turnaround time of all the processes? Be brief (1-2 sentences max) in your answer. b) If you use RR for scheduling, which of the three performance metrics (waiting, response, turnaround time) is more likely to be improved?

- Add a new class Checking Account that inherits from the BankAccount class, and has a double instance variable overdraftLimit in addition to the variables inherited from the superclass. Create a constructor for the Checking Account class that takes in the account number, account holder name, initial balance, account type and overdraft limit as input, and uses the super keyword to call the constructor of the superclass, passing in the account number, account holder name and initial balance, account type. Re-write the withdraw() method in the CheckingAccount class so that it first checks if the withdrawal amount is less than the current balance plus the overdraft limit. If it is, the withdrawal is allowed and the balance is updated. If not, the method should return an error message "Insufficient funds".
