🌐 What is a Router? (CCNA Basics Made Simple!)

A router is the brain of your network 🧠
It connects multiple networks together and ensures data reaches the right destination every time!

💡 What does a router actually do?
✔️ Connects different networks (LAN ↔ WAN)
✔️ Uses IP addresses to make decisions
✔️ Chooses the best path for data packets
✔️ Enables internet access 🌍

🔗 In this example:
➡️ Router connects two switches
➡️ Switches connect devices like:
💻 Laptops & Desktops
🖨️ Printers
📡 Access Points
📞 IP Phones
🗄️ Servers

🔥 Key Difference:
🔀 Switch → connects devices in same network
🌐 Router → connects different networks

💬 Quick Question:
At which OSI layer does a router operate? 👇

A) Layer 2
B) Layer 3
C) Layer 4
D) Layer 7
