The Operating Systems course is held with the aim of providing a fundamental understanding of how the operating system basic functions as an interface between users/applications and computer hardware. The operating system is a hardware resource manager, which consists of processor, memory, I/O and file system. Equipped with a basic understanding of operating systems, especially how resources are managed by operating systems to achieve the goal of ease of use of computer systems and optimizing resource utilization, graduates of the computer science study program are ready to face the ongoing development of operating systems, so they can utilize it appropriately and can also be a part of developing a more reliable operating system in the future.
