By delivering messages only to the connected device intended, a network switch conserves network bandwidth and offers generally better performance than a hub.

通过将消息只发送至相连的目的设备，网络交换机节约了网络带宽，提供了比集线器更好的性能。

I'm still not super-clear in my head on the differences between a hub, router and switch and how it relates to the gnomes that live inside of each.

我的脑袋里还是非常地不明白集线器，路由器和交换机之间的区别，并且也不明白他们怎么在里面联系起来的。

Network switches appear nearly identical to network hubs, but a switch generally contains more intelligence (and a slightly higher price tag) than a hub.

网络交换机看上去类似于网络集线器，但其功能一般多于集线器(价格也略高)。
