In this episode you will learn:

- Routers operate at Layer 3 to forward packets between different networks and separate broadcast domains.

- Switches operate at Layer 2, using MAC addresses to forward frames within the same local network.

- Firewalls provide stateful security by inspecting and filtering traffic based on the state of connections.

- Access Points act as a Layer 2 bridge, connecting wireless clients to a wired Ethernet network.

- The distinction between a router's role (inter-network) and a switch's role (intra-network) is a core CCNA concept.
