=====Operating Systems=====

Course catalog description:
Basic principles of operating systems: addressing modes, indexing, relative addressing, indirect addressing, stack maintenance; implementation of multitask systems; control and coordination of tasks, deadlocks, synchronization, mutual exclusion; storage management, segmentation, paging, virtual memory; protection, sharing, access control; file systems; resource management; evaluation and prediction of performance. Students are expected to spend at least three hours per week gaining hands-on experience in using and modifying a small operating system.

The course comprises both lecture-format classes to discuss course topics and practice/study/observe (PSO) sessions to give hands-on experience with the topics covered in lecture.

===== Textbook =====
D. Comer, Operating System Design - The Xinu Approach, Second Edition CRC Press, 2015. ISBN 9781498712439.

===== Grading Policy =====
Students will solve homework problems, and take in-class exams and quizzes. In addition, each student will participate in a laboratory exercise once per week. Lab problems include the design, implementation, modification, testing, and measurement of operating system components. 
The grading criteria are as follows:
  * Midterm exam: 20%
  * Final exam: 25%
  * Labs: 50%
  * Quizes: 5%
===== Late Policy =====
There is no partial credit for late assignments.  However, each student is granted three grace days (24-hour periods) that can be used for any laboratory or homework assignment any time during the semester.  The three days can be applied to a single assignment (e.g., a lab) or one day can be applied to each of three assignments.  Grace days must be used in increments of one day.  Once your three grace days have been used, no further exceptions will be made.  Grace days cannot be used to extend the due date beyond the last day of regular classes.

===== Grade Disputes =====
Feedback on graded material will be posted on Blackboard in as timely a manner as possible.  Once feedback for a graded assignment is posted, you will have 1 week from the posting date to dispute a grade.  No regrade requests will be honored after 1 week from posting feedback.

===== EMERGENCY PREPAREDNESS – A MESSAGE FROM PURDUE =====

To report an emergency, <html><span style="color:red;">call 911</span></html>. To obtain updates regarding an ongoing
emergency, sign up for Purdue Alert text messages, view http://www.purdue.edu/ea.

There are nearly 300 <html><span style="color:red;">Emergency Telephones</span></html> outdoors across campus and
in parking garages that connect directly to the PUPD. If you feel threatened or
need help, push the button and you will be connected immediately.

If we hear a <html><span style="color:red;">fire alarm</span></html> during class we will immediately suspend class,
evacuate the building, and proceed outdoors. Do not use the elevator.

If we are notified during class of a <html><span style="color:red;">Shelter in Place requirement for a tornado</span></html>
warning, we will suspend class and shelter in [the basement].

If we are notified during class of a <html><span style="color:red;">Shelter in Place requirement for a
hazardous materials release, or a civil disturbance</span></html>, including a shooting or
other use of weapons, we will suspend class and shelter in the classroom,
shutting the door and turning off the lights.
