Educational goals
The goal of the course is to cover the theoretical background required to understand the general principles and components of Operating Systems. Upon successful completion of the course the student will be able to:
- Explain the fundamental concepts and principles of operating systems
- To distinguish the objectives as well as the basic and desired characteristics of the operating systems
- Describe the elements of the operating system architecture
- Identify key issues and solutions to synchronization and process blocking problems
- Explain the I/O management and scheduling of a computer system unit
- Identify and distinguish single-processor, multiprocessor, and real-time scheduling algorithms
- To distinguish and identify the main memory management techniques
General Skills
- Search, analyze and synthesize data and information, using the necessary technologies
- Commenting on common classroom errors in class exercises
- Exercising criticism and self-criticism
- Promoting free, creative and inductive thinking
