1HW1 Explain the transition “interrupted” and “event wait.” Describe how they are different. NewReadyRunningTerminated Waiting (Blocked) admitted Dispatched to a CPU interrupted I/O or event wait I/O or event completion exit

2HW2 CPU Ready Queue admitted dispatched exit interrupted Event 1 wait Event 1 occurs Event 1 Blocked Queue Event 2 wait Event 2 Blocked Queue Event 3 wait Event 2 occurs Event 3 occurs This process mgt scheme assumes that each process waits for an event. A process may want to wait for multiple events at the same time. When can this make sense? Provide an example. How do you design process queues?

3HW3 Choose an OS, and describe –Where the OS places virtual memory –How to configure (change) the total size of virtual memory on the OS.

4HW4 For the 7-state process behavior model –Draw a queuing diagram.
