No Office Hours Next Week

Due to a business trip of the instructor, there will be no office hours on February 4.

OS This Week

This week, we will cover the rest of Chapter 5 with emphasis on Sections 5.3 (I/O SOFTWARE LAYERS), 5.4 (DISKS) and 5.8 (POWER MANAGEMENT). These sections are your reading assignments.

Since we will have the last class this week, you should be prepared to ask questions for any material covered in the class (for the preparation to the final exam).

Next week, the instructor will be on a business trip and therefore will not be available for the office hours (or any other in-person assistance). However, we plan to have an extra help session on the 2nd week of February for those in need of assistance toward the final exam.

OS Ex12 Deadline Extension

Due to the review of the past exercise problems, we extend the deadline submission of today's exercise to 1620 today. This is a hard deadline and submission system automatically closes at this time.
