Description

Modern computer software can run without specific knowledge of the underlying components of the physical machine. For instance, a program such as Microsoft Word can run on computers with varying amounts of RAM and can print a document without needing to know the make and model of the target printer. Physical resources such as memory and peripheral hardware are managed by the computer’s Operating System software. This course examines the abstractions that an Operating System provides to user-level software and how to most efficiently allocate resources between competing programs. Specifically, we will examine how to share and manage the CPU, memory, persistent storage, I/O devices, and communications.

Prerequisites

Successful completion of CS 0447 – Computer Organization and Assembly Language and CS 0449 – Introduction to Systems Programming is required to enroll in CS 1550. If you have any questions about the prerequisite material for the course, please ask at the beginning of the term.

Course Purposes and Goals

This course is intended to introduce the fundamental concepts that modern operating systems use to manage the physical computer. Beyond the concepts introduced in lecture, course projects will take one such operating system, Linux, and examine source code. Students will be asked to implement additional features into the core of the operating system, known as the kernel.

By the end of the course, students will be able to:

Class Policies

Exams:  There will be a midterm and a final. The exams will be closed book/notes. The final exam is Wednesday, December 16, 2009 during regular class time in the normal classroom.

Cheating on exams will not be tolerated.  Anyone caught cheating will be given a zero for the test and reported to the department following University procedures.

Projects:  There will be four out-of-class assignments given.  These are to be completed in the given time (no extensions will be given without a valid excuse.)  These are meant to be your own work; anyone found to be collaborating will be given a zero for the assignment.  Collaborating also means using code from previous terms, other universities, your friends, or finding it on the internet.

Quizzes:  There will be short, unannounced quizzes to make sure you are keeping up with the class material.

Participation:  Attendance will not be taken, but in a small class, any absence will be noticed.  Several unexcused missed classes will adversely affect your grade.


Grading

Your grade will be based upon 2 exams, 4 projects, quizzes (the lowest one of which will be dropped), and participation:
