1. What is the difference between a Ready State and a Waiting State?

2. When a process makes an I/O request, what state is it put into? Explain.

3. Using a round robin scheduling algorithm, when a process has its time quantum expire and is not yet done, what state does it get put into? Explain.

4. Consider preemptive and non-preemptive scheduling algorithms.

a. What is the difference between the two?

b. In a non-preemptive scheduling algorithm, is a job that is not yet completed ever taken away from the CPU and replaced with another job? Explain.

c. What is one advantage of a preemptive scheduling algorithm?

d. What is one advantage of a non-preemptive scheduling algorithm?
