求翻译：交换机同样是多个网口设备连接在一起的设备，也是通过广播传输数据，但是可以在交换机内划分vlan，不同的vlan之间不通，比集线器处理能力强。当啥都不设置时就是一个集线器。是什么意思？

Switch is also more than one network interface device to connect devices together, but can be divided into the switch through radio transmission of data, the vlan between the barrier in a different vlan than the hub processing capabilities. Consequently does not set a hub.

Switch is also more than one network port devices connected to the device, it is also through the broadcast transmission of data, but it can be divided within the switch VLAN, VLAN between the different work than a hub, handling capacity. When Nelson Mandela is not set, it is a hub.

Switch is also a multiple network interface device connected device, also through radio transmission data, but you can divide the switch VLAN, among different VLAN access, stronger than the hub processing capacity. When what's setting is a hub.
