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 This Week

This week, we will proceed to Chapter 5 "Input/Output." It is expected that we will cover first three sections of the chapter. These sections are your reading assignments.

The student who has not finished the Homework 1 needs to demonstrate that the program works this week (the last chance; no more extension)

  • In addition to the best-fit, the first-fit algorithm is also implemented and correctly working
  • the statistical information is collected and it should reflect the difference of allocation algorithms

We will review the problems of Exercises 8 and 9. Make hard copies of your own work and bring them to the class so that you will understand whether you have solved the problems correctly.

OS Next Week

On January 7, we will proceed to Chapter 4 "File Systems" and expect to cover first three sections (i.e. up to Section 4.3 "File System Implementation"). These sections are your reading assignments.

In the 2nd period, we will first review the homework 1; students need to prepare demonstration of your program using the debug input files (and hopefully your own input files).

After the review of the homework 1, we will work on the problems related to the materials covered by the lecture (i.e. Sections 4.1 to 4.3).
