Here are the solutions to the practice exams:
(only the last question has the answer).
The final exam is Thursday (12/22) at 10:05 am in room CS 1221. Good luck!
We will have a review for the final exam on Tuesday (12/20) from 10 to 11 in CS 1325.
Discussion notes from 12/12 available

We have two practice exams for the final: the first is on

This course assumes familiarity with basic computer organization (e.g., processors, memory, and I/O devices as covered in cs354) and data structures (e.g., stacks and hash tables). You will need to be able to program in
(not C++, and definitely Java) to perform the assignments in the course. If you don't have much experience in this language, don't worry (too much), we will spend some time covering background, but of course, learning on your own is important and valuable (in this class and in real life). For those of you who are new to C (e.g., you just know Java), realize this is an opportunity to broaden your skill set! (i.e., stop complaining).
However, you can check the
to see if you've missed anything.
There is also a project question mailing list (firstname.lastname@example.org). Check the email@example.com mailing list
for Q and A about the projects.
You should have ONE of the following two textbooks:
Operating Systems (3rd Edition)You should also own:
Deitel, Deitel, Choffnes
Pearson, Prentice Hall
Operating System Concepts (6th or 7th Edition)
Silberschatz, Galvin, Gagne
The C Programming Language (2nd edition)
Kernighan and Ritchie
ISBN: 0-13-110362-8 (paperback)
You must use C on the system programming assignments in the class. The best C book in the world is
Kernighan and Ritchie's
The C Programming Language.
It is worth purchasing. Also useful is
Expert C Programming
Peter Van der Linden.
Finally, if you are interested in mastering the Unix programming environment, the absolute bible is
Advanced Programming in the UNIX Environment
by the late, great
W. Richard Stevens.
Buy this book too; it is worth every penny.
Here is a short, free, and incomplete overview of the C programming environment by y.t., available for your viewing convenience in both
It would also be useful to figure out how to use the debugger,
Here is a
to a short tutorial -- there are others on the web too. Learning how to use such tools is a good idea.
Project 1 (due Thursday, September 22 at 9pm).
Project 2 (due Thursday, October 20 at 9pm).
Project 3 (due Tuesday, November 22 at 10pm).
Project 4 (due Thursday, December 15, at 10pm).
As part of the course, you will complete four or five programming assignments. You may perform these projects on PCs running the Linux operating system.
New Unix users and novice Unix users new to the CSL Unix facilities are encouraged to attend an orientation session as early in the semester as possible. You may also purchase a copy of
(An Introductory Manual to the Unix Operating System and the Computer Sciences Department's Instructional Computing Environment) at the DoIT Tech Store (first floor of the Computer Sciences and Statistics Building).
The projects are a fundamental part of this course. Although the first assignment will be relatively easy, the remaining projects each require a significant amount of time, so
do not procrastinate!
It is likely things will take longer than you expect. Do not wait until the day before the assignment is due to start. These assignments should be
started well over a week
before they are due, ideally right when they are handed out. All information necessary to complete the assignments will be available from the class web page.
As stated above, all of the assignments will be in C and not Java. We assume that you have enough programming background that learning the basics of a new language (if it is indeed new to you) will not be difficult. C is actually quite similar to Java, as those who invented Java were C experts.
For the projects, you will be graded on how well your implementation works. We will test your program on a suite of input sets. Your grade will be based on how many of the tests your application passes and how well you are able to answer our questions about the program; we will only briefly examine your code to ensure that you followed the specifications of the assignment.
