Network components and their roles: routers, switches, firewalls, IPS, access points, controllers, endpoints, and servers

By the end you’ll be able to

• Identify the primary role of routers, including interconnecting IP networks and making forwarding decisions between different subnets or networks.
• Explain the role of switches in local-area networks, including Layer 2 frame forwarding based on MAC addresses and endpoint connectivity within the same network segment.
