[B]I donnot quite understand, pc work in 7 layer but router only work in lower two layer. PC should be more powerful than router in this respective. PC can be a gateway which will change the ip to ipx or apple talk. but traditional router cannot. (of course stuff based on software donnot have scale) Therefore, I think there is some similiar in PC which has been configured as router or gateway with traditional rounter.
Love to hear from you. [/B]
不要拿Router和PC比, 我已经说过了这是两种完全不同的东西。 就像冰箱做的很智能了, 具有了某些PC的功能, 可是你会拿冰箱真正的当PC用吗? 同理, 即使PC具有了某些Router的功能, 可是还是没有人会在现实网络里拿PC当Router用的。 因为那毕竟不是同一类产品。
如果你实在理解不了,就去多看看关于Router的书, 有可能的话找台Router实实在在地试一试, 那你就可以理解为什么电信公司不用才几百美元的PC而非要用数万甚至几十万美元的路由器。 |
