Definition: network device

Hardware that operates in a network. A "network" device is a component that makes up the network infrastructure such as modems, routers and switches. A "networked" device on the other hand refers to equipment that connects to a network, which includes computers, printers and most A/V gear (receivers, media hubs and servers, Blu-ray players, etc.), which operate in an Ethernet or Wi-Fi network or both. Smartphones and tablets all have Wi-Fi but are considered "mobile devices." See network device protocol, Ethernet and Wi-Fi.
