Course Objective
This course aims to build a clear understanding of the fundamental principles that shape modern computer organization and operating systems. Students will explore how programs are structured, stored, and executed through detailed study of memory organization and related architectural concepts. The course also guides learners through the essential ideas involved in designing an operating system, enabling them to connect theoretical foundations with practical system level behavior.
