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
This course contributes to the learning outcomes I.1, I.2, II.1, II.2, III.1, III.2, V.2, VI.1, VI.2, VII.2, VII.4, VII.5 of the BSc in engineering.

Prerequisite knowledge and skills

Knowledge of the C programming language. Computation structures.

CO-REQUIS: INFO0012 and INFO9012

Planned learning activities and teaching methods

Inverted classroom.The students carry out several assignments (group and individual).

Mode of delivery (face to face, distance learning, hybrid learning)

Weekly lectures. Practical and lab sessions. Depending on the covid-19 situation, all activities may be held online.

Recommended or required readings

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

Exam(s) in session

Any session

- In-person

oral exam

Additional information:

Assignments, labs, online tests and oral exam. Note that the oral exam will be preceeded by a MCQ test: failure to achieve 50% in this test will disqualify the student from the oral exam.

The final mark is computed as the geometric mean of the various components (execpt the oral qualifying MCQ test).

Students who do not submit half of the projects will receive an absence mark for the corresponding exam session.

All resubmissions are individual.
There is no guaranteed support for projects to be resubmitted for the resit session.
