Course Overview
Course: Operating Systems Basics<br>Platform: Cisco Networking Academy<br>Completion: 13 Jan 2026<br>Mode: Online, Self-paced
Why This Certification?
1. Critical for Cybersecurity: Understanding OS is mandatory for defense.
2. Global Recognition: Cisco NetAcad is an industry standard.
3. IT Fundamentals: Covers essential Windows architecture concepts.
Core Learning Objectives
Module 1: Windows Architecture
Understanding the Hardware Abstraction Layer (HAL) and how the OS interacts with physical components.
User Mode vs. Kernel Mode
<b>User Mode:</b> Where applications run. Restricted access.<br><br><b>Kernel Mode:</b> Direct access to hardware/memory. High risk.
Windows File Systems
• NTFS: Security, large files, journaling.
• FAT32: Legacy compatibility, file size limits.
The Boot Process
1. Power On Self Test (POST)<br>2. BIOS / UEFI Initialization<br>3. Bootloader (WinLoad.efi)<br>4. Kernel Loading<br>5. System Logon
Processes & Threads
A critical part of the course was learning how the CPU schedules threads and how the OS manages active processes.
The Windows Registry
A hierarchical database that stores low-level settings for the OS and applications.
Hands-on Labs
The course wasn't just theory. I completed several practical labs involving:<br><br>✔ Exploring the Registry (RegEdit)<br>✔ Managing Processes (Task Manager)<br>✔ File System permissions
Lab Example: System Tools

Study Effort Distribution
Total Investment: ~23 Hours
Key Insight: The Security Layer
The OS is the first line of defense. Understanding permissions, users, and groups is essential for preventing unauthorized access.
