There are seven layers within the model and the layers depiction is used to help users identify what is happening within a networking system. The OSI model layers are typically described from the top layer down. The layers are described as Application, Presentation, Session, Transport, Network, Data Link, and Physical. ✅ Check out the full blog post over a

🌐 Let's Break it Down: OSI Model 🌐 Learning the Open Systems Interconnection (OSI) Model is your first step to understanding how networks really work. (And you'll be tested on it, CCST candidates!) In this short video, Yasmeen breaks down the OSI Model, explaining how data moves across networks—layer by layer. 💡 You'll learn: • The seven layers of the OSI Model. • Common protocols at each layer. • Why the OSI model is foundational to preparing for CCST certification. 🎓 Kickstart your network
