Here is the list of topics covered in this course. The mapping to chapters from the text may be modified as the course progresses.

The reading material for the various chapters are as follows:

You might check out the assignment timeline to help you plan for doing homeworks, projects and exams.


Slides from the in-class lectures will be available shortly after they are presented, depending upon how things go. Here is what we have so far:


There are 3 short homework assignments. Homeworks are to be turned in individually. Discussion of problems among students is encouraged, but when it comes to ultimately solving the problem, your answers must be your own.

Homework and due-dates will be placed here as they are defined. Here is what we have so far:


The projects (I often call them labs) are the programming assignments you will have for the course. I encourage you to work in groups of two for the projects. I'd prefer to limit the groups to only 2, but if you really want a larger group, come talk to me. Working in groups will give you valuable ``real-world'' experience as well as provide you with a ``built-in'' source for help. Do remember, however, that all exams will be taken alone. Make sure each group member understands the programs completely!

With the exception of project 0, you will need to turn in your assignments on-line. Check here for information on how to turn in your assignments.


In this section are any code samples discussed in class, practice exams or any other demonstration-type class materials. Samples will be updated soon after the discussion in class begins.

Final exam stuff:

Here is the simple "Up Yours" client-server example that shows the use of threads as in Project 4. They use the same socket libraries as the client-server sample from Project 3:

Here are the demos that have separate add and subtract threads that access a global variable:


Here is the simple "Bite Me" client-server example that shows the use of the socket wrappers used in Project 3:

Mid-term stuff:

Here are some sample semaphore and shared memory programs:

Here are some samples showing the use of software signals:

Here are some sample curses programs:

Here are some sample Java programs:

Here are some sample programs concerning Process stuff :

Here are some code samples of the SOS:

Here are some code samples from Linux:

OS Hotlinks


Linux is a completely free Unix operating system. Linux runs primarily on 386/486/Pentium PC's, but has been ported to various other architectures. If you like Unix, want to learn more about system administration and have access to a PC, I recommend checking it out. Read a short info sheet or a more detailed info sheet for more information.

I, Cringely

A weekly column by Robert X. Cringely that provides a humorous but profound look at the world of Information Technology.
"What makes Cringely such an interesting writer is the way he combines a solid understanding of technology, the ability to explain it simply, and an irreverence for those who, at the highest levels, hawk it" IEEE Spectrum, May 1997.


Your text book mentions the Nachos System in the Appendix (pages 699-714). Although this system is too advanced for an intro course on operating systems, keen students may like to look further into the Nachos software.


You might also want to check out "The Cathedral or the Bazaar", an interesting look at open source software development.

Some useful course material (e.g. slides, notes, Java simulations, etc.) includes:

You can also have a look at the Yahoo! Operating Systems pages and related WWW pages:

Or perhaps you would like to know more about some of the companies involved in commercial Operating Systems:
