OSI Model & TCP/IP Explained | 7 Layers Made Simple | Day 06

Welcome to Tech Ai Ops – Networking Ninja Journey (Noob → Pro)

In Day 06, we break down the OSI Model and TCP/IP Model — the foundation of how all networking communication works.

You’ll learn how data travels across networks layer by layer, and how these models help engineers design, troubleshoot, and understand network systems.

What you’ll learn in Day 06

• What is the OSI Model (7 layers explained)
• Functions of each OSI layer (Physical → Application)
• What is the TCP/IP Model
• Differences between OSI and TCP/IP models
• How data flows through layers (encapsulation)
• Real-world examples of how these models are used
