CMSC 421 Syllabus

Introduction to Operating Systems

Prerequisite

CMSC 341 with a grade of ‘C’ or better. CMSC 313 or (CMPE 212 and CMPE 310) with a grade of ‘C’ or better.

Description

An introduction to the fundamentals of operating systems. Topics include interprocess communication, process scheduling, deadlock, memory management, virtual memory, file systems and distributed systems. Formal principles are illustrated with examples and case studies of one or more contemporary operating systems.

Course Outcomes

Each student will:

  • Understand the fundamental concepts of operating systems including the core principles, components, and functionalities of operating systems
  • Examine process management, memory management, file systems, and device management.
  • Develop proficiency in operating system design and implementation including concepts such as process scheduling, memory allocation, synchronization, and device drivers.
  • Analyze and evaluate different operating system architectures including assessing the strengths and weaknesses of various operating system architectures.
  • Explore concurrency and synchronization mechanisms including concepts of concurrency, race conditions, and synchronization in operating systems.
  • Study memory management techniques including virtual memory, paging, segmentation, and demand paging.
  • Examine file system organization and implementation such as directory structures, file allocation methods, and access control mechanisms.
  • Investigate operating system security and protection including techniques used to protect against threats, including access control, authentication, encryption, and intrusion detection.
  • Design and develop a substantial project that involves modifying the Linux kernel, demonstrating an understanding of operating system concepts and practical implementation techniques.
