Course Description

Introduction to Computer and Operating Systems; Processes; Threads; Interprocess Communication; Process Scheduling; Process Synchronization; Deadlocks; Memory Management and Virtual Memory; File Systems: Interface and Implementation; Mass-Storage Structure and Management; Input/Output Systems; Examples from Operating Systems such as Linux and Windows.
Credit units: 4. ECTS Credit units: 6.5.
Prerequisites: CS 202 and CS 224 are mandatory. You are recommended to take this course in the second semester of your third year in the curriculum, after taking the courses like MATH 230 (Probability and Statistics) and CS 315 (Programming Languages). Part of homeworks and projects will require Probability and Statistics knowledge to do experiments and analyze the results.

Textbooks

Grading Policy (tentative)

Projects: 30%. Around 4 projects.
Homeworks-Quizes: 10%.
Midterm: 30%. Closed book and notes.
Final exam: 30%. Will cover all topics. Closed book and notes.
Note that passing the course without taking a midterm exam or final exam is not possible. If you don't take an exam and the associated makeups you will get an FX from the course. You need to have a doctor report to take a makeup exam. If you did not take an exam and have a doctor report, you need to inform the instructor immediately so that you can take a makeup exam.
You should expect a makeup exam to be more difficult, since you have more time to study.
Students whose project average is less than a threshold value will not be able to pass the course (will get F), no matter what the other grades are. Threshold may be determined after final exams. You should expect project threshold to be around 40/100 (project average) (tentative and may change).
You should expect F threshold to be around 40-45/100 (course total) (tentative and may change).
Attendance is mandatory. A student missing for more than 25 % will fail the course automatically (will get FZ, FX, or F), no matter what the grades are. Hence required attendance is 75 % of all lectures hours done by the end of semester. It is the responsibility of the student to join to a zoom session with an email address that is registered in STARS so that attendance for the student can be checked; otherwise student will be absent from the session.
Grades are posted to the SAPS system.

Other Information

There will be around 4 projects. Projects are very important and will be done in Linux operating system using C programming language, unless otherwise stated. Every student needs to do her best to do a project. The teaching/learning approach of the course will be Learning by Doing. Therefore it is very important that you do the projects to really learn and understand in a long-lasting manner.
Exams may include questions from homeworks and projects.
We may do a quiz at any time (pop-up quiz).
Some projects/homeworks may be done in groups.
You need to learn C immediately. Today, buy a C book and start writing some small C programs. Make sure that you can write programs in C.
All 4 hours in a week may be used if necessary.

ABET

The course addresses the following ABET outcomes:

b5) Able to design and conduct system level experiments and analyze the results.
[measured through parts of Homeworks and Projects. Reports are used in projects. Out of 5.] Will require Probability and Statistics Knowledge.
c2) Able to design and implement a software system to meet desired needs.
[measured through Projects. Out of 20. ]
e3) Able to solve engineering problems related to computer systems and applications.
[measured through Midterm and Final Exams. Selected questions - one or more questions in midterm(s) and/or final exam will be used to measure. Out of 100. ]

Academic Honesty

Plagiarism is defined as the action of using or copying someone else's idea or work and pretending that you thought of it, or created it. Bilkent University requires that you be aware of the concept and dangers of plagiarism. In order to conform to international academic standards, you must respect the individual thoughts, ideas, and expressions of other authors in sources. In the exams, home-works, and projects in this course, occurrences of plagiarism will be seriously dealt with, leading to punishment through disciplinary procedures which call for a term or two terms of dispelling from the university.
