Complex rules limit the topology and the use of hubs in Ethernet networks, but I'll skip those as I doubt anyone still has interest in building a large scale Ethernet network using repeater hubs.
在以太网络环境里，复杂的规则制约了集线器的拓扑结构和使用范围。考虑到如今应该没人再对如何使用集线器搭建一个规模巨大的以太网感兴趣了，具体细节姑且不表。
For example, with the Ethernet, network standard packets are echoed to all physical ports and, by scanning all the packets that go past on the network, you can examine the content.
例如，对于以太网来说，网络标准数据包将发送到所有的物理端口，并且通过扫描通过网络传输的所有数据包，您可以检查其中的内容。
