Course description and aims

Operating systems (OS) is software that abstract computer hardware and manages computer resources. In this lecture, we explain the basic concepts and functions of OSes. Also, deepen understanding through exercises.

Student learning outcomes

A student understands and master te following basic concepts and functions. In particular, he/she can make efficient use of hardware by understaindng how OSes connect application software and hardware.
- OS startup
- Input / output
- Filesystem
- Process management: loading and executing programs
- Process management: concurrent processing, scheduling
- concurrency control (synchronization)
- memory management
- virtualization
- networking
- security


Operating system, hardware abstraction, resource management

Competencies that will be developed

Specialist skills Intercultural skills Communication skills Critical thinking skills Practical and/or problem-solving skills

Class flow

In the lecture time, lextures are given and assignments are explained.

On assignment will be given as homework for each one or two lectures.

Out-of-Class Study Time (Preparation and Review)

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.



Reference books, course materials, etc.

Lecture the main parts of the following reference books. Silberschatz and Galvin: Operating System Concepts, 9th ed., John Wiley & Sons, 2012.
In addition, reference materials will be instructed as appropriate during the lecture.

Assessment criteria and methods

Evaluate students' udnerstanding of the basic functions of the operating system. Grades are determined based on assignments.
