Bridges define broadcast domain while switches define collision domains.
这句怎么是对的，能解释一下吗，谢谢
原题是：
With regard to bridges and switches, which of the following statements are true?
(Choose three.)
C. Bridges are frequently faster than switches.
D. Switches typically have a higher number of ports than bridges.
E. Bridges define broadcast domain while switches define collision domains.
F. Both bridges and switches make forwarding decisions based on Layer 2 addresses.
呵呵，还有ab没写上：
A. Switches are primarily software based while bridges are hardware based.
B. Both bridges and switches forward Layer 2 broadcasts.
TK上的答案是BEF，我觉得是BDF

网桥定义广播范围，而交换机定义冲突域。
网桥只是用来传播广播的物理设备，而交换机是一个智能设备，可以缩小冲突域的。
网桥并不划分冲突域
而交换机 每个端口作为一个冲突域
答案应该是 DEF 吧？
