确实如此.但是如果连接在网络上的计算机越来越多，那么碰撞的现象会越来越频繁.这样效率一定很低了.恩.这里还有一个重要概念"冲突域 ".在同一个物理上连接的网络上的所有设备是属于同一个冲突域的.
接着就需要引入我们的2层设备来分割冲突域了.
网桥(Bridge) 就是连接2个不同的物理网络的.主要功能是在2个网络之间转发Frame.因为从实际中我们可以知道.其实很多时候并非整个网络都在相互通讯.多相互通讯的一组计算机我们可以分在一个小的冲突域内.这样分割以后可以减少冲突域，也就相对的减少了冲突的机会.而之间使用网桥来桥接，由于网桥两边的通讯不是非常频繁，所以使用网桥来为2边作为"代言人".这样任意一个小网络里面产生冲突的机会就少了.
