Ethernet is a system for linking computers so they can share files, printers, and a connection in the same building or on the same local network. In daily talk people mostly mean the cable with a little clip that clicks into a laptop or a wall socket, and the boxes and ports that go with it. Shop staff and office IT people use the word all the time; it is technical, but not rare or fancy.

Wi-Fi does a similar local job without a wire, so people stretch “Ethernet” to mean “the wired kind, not Wi-Fi.” The name began as a Xerox trademark. The picture was that messages would move through the network the way older science imagined light moving through “ether,” an invisible stuff filling space.

Wi-Fi does a similar local job without a wireWi-Fi做的是類似的區域工作，但不用線，so people stretch “Ethernet” to mean “the wired kind, not Wi-Fi.”所以大家會把「Ethernet」延伸用來指「有線的那種，不是Wi-Fi」。The name began as a Xerox trademark這個名字一開始是全錄（Xerox）的商標。The picture was that messages would move through the network the way older science imagined light moving through “ether,” an invisible stuff filling space當初的畫面是，訊息會在網路裡移動，就像早期科學想像光會透過「ether（以太）」——一種填滿空間、看不見的東西——移動一樣。
