The CCNA course covers a wide range of topics that form the backbone of networking knowledge. Here’s what you’ll learn:

🔌 Networking Basics

  • How computers communicate over a network

  • What IP addresses and subnets are

  • The difference between LAN (Local Area Network) and WAN (Wide Area Network)

🧭 Routing and Switching

  • How data travels from one place to another using routers

  • How switches create efficient local networks

  • Setting up VLANs (Virtual LANs) for better traffic management

🌐 IP Addressing & Subnetting

  • Assigning IP addresses manually and automatically

  • Breaking down a network into smaller sub-networks

🔐 Network Security
