Description: This course provides an introduction to computer systems from a programmer's perspective. Topics include machine-level representation of data and programs, linking and loading, processes, virtual memory and memory allocation.

Prerequisites: Grade of C or better in CS 262 (or CS 222) and grade of C or better in ECE 301 (or ECE 331).
Prerequisites will be strictly enforced.

Course Outcomes: Upon completion of this course, students should be able to:

• Demonstrate an ability to design and implement C programs that use dynamic memory allocation and advanced data structures.
• Demonstrate knowledge of computer arithmetic and logic operations and representations of data at the machine-level.
• Demonstrate knowledge of machine-level representations of (C) programs.
• Demonstrate an ability to use debuggers.
• Demonstrate an understanding of object file linking and related ideas such as relocatable object files and symbol resolution.
• Demonstrate an understanding of the idea of a process, how processes are created and laid out in memory, how processes use virtual memory, and how they are manipulated via interrupts, signals, and context switches.
• Demonstrate an understanding of dynamic memory allocation and garbage collection schemes.

Readings: The required textbook is Computer Systems: A Programmer's Perspective by Randal Bryant and David O'Hallaron (Prentice Hall, Second Edition, 2011).

Graduate Teaching Assistant (GTA): Nasrin Akhter (nakhter3@masonlive.gmu.edu)
GTA Office Hours: Wednesday and Friday, 11:00 AM – 1:00 PM, and by appointment (location TBD)

Undergraduate Teaching Assistants (UTAs):
Tien Khoa "TK" Nguyen (tnguye90@masonlive.gmu.edu)
Office Hours: Monday 10:45 AM – 11:45 AM; Tuesday 3:00 PM – 5:00 PM (location TBD)
Kevin Dec (kdec@masonlive.gmu.edu)
Office Hours: Tuesday 11:00 AM – 12:00 noon; Thursday 3:00 PM – 5:00 PM (location TBD)

Grading: Grading components will be as follows.

• Homeworks and Quizzes: 20%
• Lab assignments: 35%
• Midterm exams: 20%
• Final exam: 25%

No early midterm/final exams will be given and make-up exams are strongly discouraged.  A student should present an official and verifiable excuse to miss a midterm/final exam (such as a doctor's note).

All exams are closed book. The final exam will be cumulative; that is, it will include all topics discussed during the term. Unlike the midterm and final exams, the timing of the quizzes will not be announced in advance.

Late homework/assignment submissions will be marked down 25% for each day. The students are responsible for keeping back-ups of their work while they are working on an assignment.

All students must abide by the GMU Honor Code and CS Department's Honor Code and Academic Integrity Policies during the semester. The students are supposed to work individually on the assignments. Collaboration will be allowed only for the group assignments/labs, within each group. We reserve the right to use automated tools such as MOSS to detect plagiarism. Violations of the Honor Code will result in an F. Those violations will be also reported to the GMU Honor Council.

Class Home Page: Throughout the term, all course material (announcements, slides, handouts, etc.) will be available on the GMU Blackboard system and/or the Piazza system (Section 001, Section 002), as determined by the instructor of the section.

Computer Accounts: All students should have accounts on VSE Unix cluster (aka zeus.ite.gmu.edu). Instructions and related links can be found here. Your programs will be tested and graded on the VSE Unix Cluster. If you develop your programs on systems other than zeus, it will be your responsibility to port them to zeus before the submission deadlines.

Contacting the instructors/TAs: The preferred communication medium is Piazza. The students can send private messages to the instructors (professor, GTA, UTA) as well as post public questions visible to all students and tag everything by topic. The students should make sure to sign up to the Piazza page of their own section.

Classroom Behavior: During the lectures, the students should avoid behavior that may distract others, including chatting, sleeping, playing games. The use of electronic devices (including laptops, tablets, cell phones, smartphones, etc.) is not allowed in this class. If you feel that your learning will be hampered by not having access to your tablet/laptop computer for note-taking or other course-related purpose, you should speak to the instructor at the beginning of the term.

Disability Statement: If you have a learning or physical difference that may affect your academic work, you will need to furnish appropriate documentation to GMU Disability Resource Center. If you qualify for accommodation, the DRC staff will give you a form detailing appropriate accommodations for your instructor. If you have such a condition, you must talk to the instructor during the first week of the term about the issue.
