Operating Systems Overview

Operating Systems (OS) are the foundational software that manages computer hardware and provides common services for computer programs. They act as an intermediary between users/applications and the physical hardware.

Learning Path​

This documentation series covers the core concepts and modern implementations of operating systems:

  1. Introduction: Goals, history, and basic structures.
  2. Process Management: How OS manages multiple tasks.
  3. Threads & Concurrency: Managing simultaneous execution and synchronization.
  4. Memory Management: Handling physical and virtual memory.
  5. File Systems: Organizing and storing data.
  6. I/O Systems: Interfacing with external devices.
  7. Storage Systems: Managing disks and RAID.
  8. Security & Protection: Protecting system resources and data.
  9. Virtualization: Hypervisors and container technology.
  10. Linux Essentials: Practical tools and performance analysis.

Key OS Functions​

  • Resource Management: Allocation of CPU, memory, and I/O.
  • Process Coordination: Scheduling and synchronization.
  • Data Persistence: File system and storage management.
  • Security: Access control and isolation.
  • Abstraction: Providing a consistent API (System Calls) across different hardware.
