COMP2006J Operating Systems

Academic Year 2024/2025

The course is structured in such a way as to present important concepts of operating systems. The emphasis is on fundamental topics and techniques, although references to actual systems are made as well in order to illustrate concepts and/or implementation issues. The introduction is devoted to a brief history of operating systems, and their design issues and philosophies. The main components of an operating system are explained, and different approaches to how these components are organised and implemented are presented. This is followed by another very important topic, which is process management. The notion of process helps to explain, understand and control the execution of programs in an OS. This leads to the subject of how processes are organised (communication, cooperation, and synchronisation). Next we study process scheduling, which is at the heart of any multiprogrammed operating systems. We follow by studying memory management. More precisely we focus on the concepts of segmentation, paging, and virtual memory. Another key component that we study is the file system. Interference in resource utilisation is a serious threat in an OS. Two complementary sets of techniques to counter security threats are presented: protection and security.

Learning Outcomes:

Upon completion of this module, the students should be able to explain what an operating system is, and why we study operating systems; be able to use the concept of process and concurrency; understand the issues and techniques associated with process synchronization (deadlock, starvation); understand process scheduling; understand memory management, real memory and virtual memory; define and apply the concept and mechanisms of file systems; demonstrate and formulate protection and security mechanisms; and evaluate the complexity of building an operating system.
