CS149: Introduction to Operating Systems

Course Syllabus Spring 2010

San Jose State University

 

 

 

 

Description:††† Introduction to computer operating systems principles.Topics for discussion will focus on the fundamental responsibilities of an operating system kernel including hierarchical memory management, CPU and task scheduling, resource management, input/output processing, and file management.Several alternative algorithms associated with the implementation for each of the major topics will be studied along with an analysis of their properties, advantages, and disadvantages.Hardware characteristics of generic computer architectures and devices are analyzed to the extent necessary to emphasize the role of the operating system as a resource manager and controller.Related topics such as inter-process communication and synchronization, deadlocks, reliability, security, and distributed systems are also presented.Programming projects will be used to demonstrate implementation techniques for various ideas presented in class.

Student Learning Outcomes:

 

Upon successful completion of this course, students should be able to understand:

 

       The role that the operating system software plays in the management of the various hardware subsystems of the computer system

       The memory hierarchy including Locality of reference and how it is used to perform effective memory hierarchy management, the various mapping, replacement, and dynamic allocation algorithms for cache and virtual memory management

       The alternative CPU scheduling schemes, their tradeoffs, and their applications to other queue processing situations

       Why and how deadlocks can happen, the difficult tradeoffs faced when attempting to deal with the resource deadlock problem, and distinguish between the different deadlock prevention and avoidance schemes

       Software race conditions, their origin and the problems they can cause, along with knowing how to apply semaphores to mitigate the race condition problem

       The various operating systems issues associated with I/O and file management.

General University Policies

 

DISABILITIES:

If you need course adaptations or accommodations because of a disability, or if you need special arrangements in case the building must be evacuated, please inform the instructor as soon as possible.Presidential Directive 97-03 requires that students with disabilities register with DRC to establish a record of their disability.

 

ACADEMIC INTEGRITY:

Academic integrity is essential to the mission of San Josť State University.  As such, students are expected to perform their own work (except when collaboration is expressly permitted by the course instructor) without the use of any outside resources.  Students are not permitted to use old tests, quizzes when preparing for exams, nor may they consult with students who have already taken the exam. When practiced, academic integrity ensures that all students are fairly graded. Violations to the Academic Integrity Policy undermine the educational process and will not be tolerated.  It also demonstrates a lack of respect for oneself, fellow students and the course instructor and can ruin the universityís reputation and the value of the degrees it offers.

 

We all share the obligation to maintain an environment which practices academic integrity.  Violators of the Academic Integrity Policy will be subject to failing this course and being reported to the Office of Judicial Affairs for disciplinary action which could result in suspension or expulsion from San Josť State University.

 

CHEATING:

At SJSU, cheating is the act of obtaining or attempting to obtain credit for academic work through the use of any dishonest, deceptive, or fraudulent means. Cheating at SJSU includes but is not limited to:

 

Copying in part or in whole, from anotherís test or other evaluation instrument; Submitting work previously graded in another course unless this has been approved by the course instructor or by departmental policy.Submitting work simultaneously presented in two courses, unless this has been approved by both course instructors or by departmental policy.Altering or interfering with grading or grading instructions; Sitting for an examination by a surrogate, or as a surrogate; any other act committed by a student in the course of his or her academic work which defrauds or misrepresents, including aiding or abetting in any of the actions defined above.

 

PLAGIARISM:

At SJSU, plagiarism is the act of representing the work of another as oneís own (without giving appropriate credit) regardless of how that work was obtained, and submitting it to fulfill academic requirements. Plagiarism at SJSU includes but is not limited to:

 

The act of incorporating the ideas, words, sentences, paragraphs, or parts thereof, or the specific substances of anotherís work, without giving appropriate credit, and representing the product as oneís own work; and representing anotherís artistic/scholarly works such as musical compositions, computer programs, photographs, painting, drawing, sculptures, or similar works as oneís own.
