An operating system is the most basic system program of a computer, and is an essential system for using a computer.
In this lecture, we aim to understand what kind of problems exist in operating systems, how they are considered, how they are solved, and how they are realized.
Students will also learn how these issues are specifically dealt with in UNIX which is one of the most widely used operating systems today.
A quiz will be given in several classes to check students' understanding.
Midterm and final exams will be held during class hours.
In addition, this class for the 2025 academic year will be in accordance with the university's policy, face-to-face classes will be held in the classroom as a general rule.

In order to design and develop applications, manage computer systems, or design and develop complex systems using various
functions of computers, knowledge beyond that of application users is required.
For example, knowledge of the need for management of computer hardware and software, how they are managed, and why such management is necessary.
As the most basic software of a computer, an operating system is software that manages not only hardware and software, but also everything related to processing on a computer including time and users.
Therefore, learning about operating systems leads to a deeper understanding of computers, and through that understanding, one gains the knowledge that leads to the design and development of the aforementioned systems.

- Students will understand what it means to manage a computer system and will be able to express the results concretely.
- Students will be able to explain what kind of issues exist for more convenient use of computer systems.
- Students will be able to explain concretely how the above issues are perceived, considered, and resolved.
