Comprehensive Guide to the OSI Model: Exploring the 7 Networking Layers

Understanding the OSI Model is essential for anyone in networking, cybersecurity, or IT support.

In this video, we explain the 7 layers of the OSI Model in a simple and visual way. From hardware to software, this model helps organize and troubleshoot how data flows through a network.

📚 OSI Layers Covered:

Physical Layer – Hardware like cables, NICs, switches

Data Link Layer – Node-to-node transfer (MAC addresses, switches)

Network Layer – Routing and IP addressing (Routers, IPs)

Transport Layer – End-to-end connections (TCP/UDP, video calls)

Presentation Layer – Data formatting & encryption (SSL/TLS)

Application Layer – Direct user interaction (Email, web, FTP)

🔍 Real-life Examples Included!

🧠 Ideal for students, CCNA/CompTIA learners, and IT professionals.
