集线器(HUB)是对网络进行会集管理的最小单元,像树的主干相同,它是各分枝的汇集点。HUB是一个共享设备,其实质是一个中继器,而中继器的主要功能是对接收到的信号进行再生扩展,以扩展网络的传输距离。恰是因为HUB仅仅一个信号扩展和中转的设备,所以它不具有自动寻址才干,即不具有交换作用。

(The hub (HUB) is the smallest unit that manages the network collectively. Like the trunk of the tree, it is the gathering point of each branch. HUB is a shared device, and its essence is a repeater, and the main function of the repeater is to regenerate and expand the received signal to extend the transmission distance of the network. It is precisely because the HUB is only a device for signal expansion and transfer, so it does not have the ability to automatically address, that is, it does not have an exchange function.)
