      Course Description

      Operating systems are central to computing activities. An operating system is a program that acts as an intermediary between a user of a computer and the computer hardware. Two primary aims of an operating system are to manage resources (e.g. CPU time, memory) and to control users and software. Operating system design goals are often contradictory and vary depending of user, software, and hardware criteria. This course describes the fundamental concept behind operating systems, and examines the ways that design goals can be achieved.

      Course Learning Outcome

      CLO1 Able to explain and analyze the functions, facilities, structure, environment and security of operating systems.
      CLO2 Able to investigate operating system administrative functions and can build shell program for process and file system management with system calls.
      CLO3 Able to analyze the performance and can apply different algorithms used in major components of operating systems, such as scheduler, memory manager, concurrency control manager and mass-storage manager, I/O manager.
      CLO4 Able to select, implement and justify recommending an operating system for a specified application and system configuration.

      Course Objective

      • To learn the fundamentals of Operating Systems.
      • To learn the mechanisms of OS to handle processes and threads and their communication.
      • To learn the mechanisms involved in memory management in contemporary OS.
      • To gain knowledge on distributed operating system concepts that includes architecture, mutual exclusion algorithms, deadlock detection algorithms and agreement protocols.
      • To know the components and management aspects of concurrency management.
      • To learn programmatically to implement simple OS mechanisms.

      Welcome my students to the course of Operating System. We teacher, can open the door, but you must enter it yourself.

  • Week 7: Mid Term

    During this pandemic time, in order to support the quality aspects of teaching and learning, online open book examinations for mid-exam  will be conducted by the department instead of traditional proctored exam.
    You will use Internet connection to log into the DIU Blended Learning Center (DIU BLC) on your respective course on the day of the examination as per the exam routine of the department. The examination will be configured to support the examination schedule and you will be allowed soon it opens the exam.
    You need to download (1) ExamPaper.pdf and (2) AnswerScriptTemplate.doc from the Mid-exam exam section of the week in DIUBLC class. You will type your answers in the answer script doc file and save as pdf with your ID e.g. CSE134-O1-111-15-2345-mid.pdf (Course Code-Section-Student ID)  and upload in the BLC within the given time frame.
    For more details please download the Open book exam guideline.
