集线器的工作方式如下：

　　1. 接收数据：当一台计算机发送数据帧到集线器时，集线器会将数据帧复制到所有其他端口上。

　　2. 将数据帧传输到目标计算机：所有连接在集线器上的计算机都会接收到数据帧。但是，只有MAC地址与数据帧中目标地址匹配的计算机才会处理数据帧，其他计算机会将其丢弃。

　　3. 处理碰撞：当多台计算机同时发送数据时，会发生碰撞。集线器会将这些碰撞的数据帧丢弃，并等待一个随机的时间段，然后重新尝试发送数据。

　　4. 传输速度：集线器的传输速度取决于其连接的设备的数量，以及它的速度等级。典型的集线器可以以10Mbps或100Mbps的速度工作。有些集线器支持1Gbps及更高的速度。

　　总体来说，集线器是一种较为简单的设备，它可以将多台计算机连接在一起，形成一个局域网。但是它无法提供路由功能和数据筛选能力，因此在现代网络中已经被大量取代。
