Hey Marisa,
Thank you for the clear explanation. I really appreciate how you broke down the roles of modems, routers, and switches because it makes understanding network troubleshooting much easier. I especially liked your point about modems helping technicians determine whether issues are on the provider’s side or the local network, which is such a practical step in real-world troubleshooting. Your explanation of routers handling NAT, DHCP, and firewalls along with switches improving efficiency and security within a LAN highlight how interconnected and essential these devices are for home and small business networks. This gives a solid framework for anyone looking to understand or troubleshoot network connectivity.
