Aims and Objectives

This module introduces the basic concepts in operating systems and links it with contemporary operating systems (eg. Unix/Linux and Windows). It focuses on OS structuring and architecture, processes, memory management, concurrency and file systems. Topics include kernel architecture, system calls, interrupts, models of processes, process abstraction and services, scheduling, review of physical memory and memory management hardware, kernel memory management, virtual memory and paging, caches, working set, deadlock, mutual exclusion, synchronization mechanisms, data and metadata in file systems, directories and structure, file system abstraction and operations. Examples will be discussed from contemporary operating systems such as Unix/Linux and/or Windows.

    • Dear Caitlyn,

      Without valid reasons, the policy is 0.1 marks for every late minute.

      Please email me if you have a strong justification to request for an extension.

  1. This is kind of late but is the first edition of Modern Operating Systems good enough for the course or are there significant differences between it and the later editions?

    • Yes, there are some differences, especially in the chapter on Linux. Ordering of chapters changed as well. It is best to get borrow an updated copy and compare the differences.

  2. Hi Prof, I saw that there is some changes to the assessment criteria. In the introductory lecture, you mention that the assessment is as of below:
    50% final
    30% lab
    20% mid-term

    May I know which one is the finalized assessment criteria? Thank you..
