@data.shola: The OSI Model can seem confusing when you first get into networking, but once you understand what each layer actually does, troubleshooting starts to make a lot more sense. From physical cables at Layer 1, to switches and MAC addresses at Layer 2, routing and IP addresses at Layer 3, all the way up to the applications we interact with at Layer 7 — each layer plays a role in how devices communicate. Don’t just memorize the 7 layers for an exam. Understand what happens at each one. 💻🌐 #networking #cybersecurity #NetworkEngineer #CCNA #TechTips
