This schematic depicts a typical home or small office wireless network architecture. Component 1 is an Ethernet wall jack feeding into component 2 (a modem or gateway), which connects via cable to component 3-the wireless router (labeled A)-that emits Wi-Fi signals (pink arcs) to multiple client devices (labeled C), including smartphones and laptops. The green lines represent wireless connections, while the purple dashed line indicates the wired link between modem and router.

Used on networking tutorials, ISP support pages, or tech education sites to explain basic Wi-Fi infrastructure; matches user intent to understand how devices connect to the internet at home.
