🚀 Master Computer Networks in one sitting! Whether you are a Computer Science student preparing for exams, an aspiring IT professional studying for the CCNA, or a developer wanting to understand how the internet actually works—this video is your ultimate guide. In this "One Shot" masterclass, we break down the complex world of networking into digestible, logical chapters. We move from the absolute basics of LANs and WANs, deep dive into the OSI layers, and finish with real-world protocols like HTTP, DNS, and IP Addressing. No prior knowledge? No problem. We start from scratch. 📝 Resources & Links 📄 Download the PDF Notes/Slides: 🧠 What You Will Learn By the end of this video, you will be able to: Understand Architecture: Differentiate between Client-Server and Peer-to-Peer networks.
