But even with clever tricks like Exponential Backoff, you could never have an entire university’s worth of computers on one shared ethernet cable.

但即使使用像指数退避这样的巧妙技巧，你也永远不可能在一根共享的以太网电缆上拥有一整所大学的计算机。

If you don't have Wi-Fi, but you do have a modem and you want to connect your computer to the modem, you're going to use an ethernet cable to do that.

如果你没有 Wi-Fi， 但你有调制解调器， 并且你想将计算机连接到调制解调器，你将使用以太网电缆来实现。
