🌐 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

🌐OSI Layers & Protocols — The Language of Networking If you want to build a career in Networking, Cybersecurity, Cloud or DevOps, then understanding the OSI Model & its protocols is absolutely essential. The OSI Model explains HOW data travels across a network — step by step: 📶 Layer 1 – Physical: Cables, signals, NICs 🧾 Layer 2 – Data Link: MAC, ARP, VLAN, STP 🌍 Layer 3 – Network: IP, OSPF, ICMP, EIGRP, BGP 📦 Layer 4 – Transport: TCP/UDP, reliability 🔄 Layer 5 – Session: Connection contro
