Скачать или смотреть The OSI Model

The OSI Model is one of the most important concepts in computer networking.
It explains how data moves, why communication works, and where cybersecurity actually happens across the seven layers.

If the network is the backbone of the internet,
the OSI Model is the blueprint that holds everything together.

I just released a simple, beginner-friendly breakdown of the OSI Model for anyone learning networking, CCNA, cloud, or cybersecurity.

Understanding this model is the first step toward truly understanding how the digital world works.
