Any sections not marked as "updated" may be subject to change.


  1. This version of these course notes was originally assembled Spring 2006 by John Bell, for CS 385 at the University of Illinois Chicago and is currently being updated ( again ) for Spring 2013.
  2. The required textbook for this course is "Operating System Concepts, Ninth Edition " by Silberschatz, Galvin, and Gagne. Most of the material in these pages was originally taken from the seventh edition of that book, later updated to the eighth edition, and then to the ninth edition.
  3. Some material was taken from the current literature in the field of operating systems and similar sources. Accreditation for these items is provided where such material appears.

Course Notes, by Topic ( and Chapter Where Appropriate )

Note: Any topic which does not have a page linked to it, or for which the linked page is unavailable, is under consideration and/or under development, and is subject to change. In particular, "future" chapters have probably not been updated from edition 7 to edition 8.

Disclaimer: The following note pages are just that - notes. They serve as reminders to myself of what I want to talk about, but not much more. They do not replace the need for students to take their own notes during class, and they certainly do not replace reading and studying the material in the required textbook.
