Briefly explain routing versus switching and one common misconception about it.

# Routing vs Switching **Switching** operates at Layer 2 (Data Link) and forwards data between devices on the *same* local network using MAC addresses. Switches learn which devices are connected to which ports and create a direct path for communication. **Routing** operates at Layer 3 (Network) and forwards data *between different* networks using IP addresses. Routers determine the best path for data to travel across multiple networks to reach its destination. ## Common Misconception Many people believe **"routers are just smarter switches"** or that they perform the same function at different speeds. In reality, they serve fundamentally different purposes: - A switch connects devices within a network (like connecting computers in your home) - A router connects different networks together (like connecting your home network to the internet) While modern devices often combine both functions (like home "routers" that include built-in switches), the core operations remain distinct. You can't simply replace a router with a switch and expect internet connectivity, as switches alone cannot route traffic between separate networks.
