Welcome to the MOOC on Operating Systems!

An Operating System (OS) is the essential software layer that powers our devices, enabling seamless interaction with hardware. It manages tasks like running applications, resource allocation, and ensuring system security, making it the backbone of modern computing.

This course offers a comprehensive understanding of how computers work, enhancing technical knowledge and problem-solving skills. Learners will explore key concepts such as resource management, multitasking, memory allocation, and security protocols, equipping them to design secure, efficient, and reliable systems.

The primary goal is to introduce fundamental concepts in operating system implementation, with a special focus on UNIX OS. The course covers OS architecture, services, and design trade-offs, fostering the ability to compare, analyze, and evaluate various design choices effectively. This foundation prepares learners for advanced topics and careers in systems administration, software engineering, and cybersecurity, empowering them to tackle complex IT challenges confidently.

Course Outcomes

Describe the architecture, services, and functionalities of operating systems, with a focus on UNIX/Linux
