Prerequisite or corequisite units are presented within each program

Learning unit contents

The goal of this course is to introduce the fundamental concepts and mechanisms used in operating systems. The content covers:

  • Introduction/Overview: multi-programming; OS as a service; OS as a resource manager; OS organisation.
  • Process management: computation abstraction; process, thread, multi-threading; inter-process communication; scheduling.
  • Memory management: allocation strategies; dynamic address relocation; virtual memory.
  • Storage management: file system structure; file system usage; file system implementation; protection; networked file system.
  • Introduction to virtualisation: system virtualisation; paravirtualisation; kernel virtualisation.

Learning outcomes of the learning unit

In this course, the students:

  • learn the principles, core concepts and organisation of modern operating systems
  • acquire practical system programming skills

Prerequisite knowledge and skills

Knowledge of the C programming language. Computation structures.

Planned learning activities and teaching methods

Lectures, practicals and lab sessions.The students carry out several  programming assignments (group).

Mode of delivery (face-to-face ; distance-learning)

Weekly lectures. Practical and lab sessions.

Recommended or required readings

Recommended readings: Operating System Concepts; Silberschatz, Galvin, Gagne; Wiley. Operating Systems Design and Implementation; Tannenbaum, Woodhull; Prentice Hall.

Assessment methods and criteria

Oral exam and  group assignments. The assignments count towards 40% of the final mark, while the exam counts towards 60% of the final mark. Students who do not submit half of the projects will receive an absence mark for the corresponding exam session. There is no guaranteed support for projects to be resubmitted for the resit session.
