3 0 0 3


Prerequisites:

  • A course on “Computer Programming and Data Structures”.
  • A course on “Computer Organization and Architecture”.

Course Objectives:

  • Provide an introduction to operating system concepts (i.e., processes, threads, scheduling, synchronization, deadlocks, memory management, file and I/O subsystems and protection)
  • Introduce the issues to be considered in the design and development of operating system
  • Introduce basic Unix commands, system call interface for process management, interprocess communication and I/O in Unix

Course Outcomes:

  • Will be able to control access to a computer and the files that may be shared
  • Demonstrate the knowledge of the components of computer and their respective roles in computing.
  • Ability to recognize and resolve user problems with standard operating environments.
  • Gain practical knowledge of how programming languages, operating systems, and architectures interact and how to use each effectively.
