About Course

The “Principles of Operating System” course is designed to teach you the fundamental concepts, structures, and internal mechanisms that power modern computing devices. You will explore critical functions such as process management, CPU scheduling, memory allocation, input/output systems, and file management. Beyond the basics, this course introduces various environments—including UNIX/Linux, Windows, macOS, and embedded operating systems—and tackles contemporary IT challenges like system security, distributed systems, virtualization, and cloud computing models (IaaS, PaaS, SaaS).

What Will You Learn?

  • OS Fundamentals: Understand the role, functions, and components of various operating systems (batch, time-sharing, real-time, embedded).
  • Process Management: Differentiate between processes and threads, understand process states, and evaluate different CPU scheduling algorithms (FCFS, SJF, Round Robin).
  • Concurrency Control: Analyze synchronization mechanisms and evaluate deadlock prevention and avoidance strategies.
  • Memory Management: Explore logical vs. physical addresses, memory allocation schemes, and virtual memory (paging and segmentation).
  • Storage & I/O: Design simple file systems, compare file organization types, and understand I/O techniques (DMA, interrupt-driven I/O).
  • System Security: Identify common security threats, configure basic security settings, and utilize protection mechanisms (ACLs, memory protection).
  • Advanced Topics: Explore contemporary trends like distributed systems, virtualization (VMware, VirtualBox), and cloud computing platforms (AWS, Azure, Google Cloud).
