在金庸的小说里面提到了『欲练神功，挥刀自宫』才能练成无敌的葵花宝典，
另外，金大侠也提到太极拳的学习到最后需要将所学的忘光光，此时才能『无招胜有招』。
呵呵～这跟 Linux 有啥关系呐？在前一章我们不是提到关于『<a
href="0105beforeserver.php">架站前的技巧分析</a>』吗？里面提到在 Linux 里面想要玩架站，
最重要的是得要搞熟 Linux 相关的操作技巧，这些技巧在一开始时真的得要花很多时间去熟悉，
真的会让人觉得好像已经『自宫』的样子！不过，别担心，
等您花时间学习过后，肯定让您忘不了了！因为那时您已经『无招胜有招』啦！
发生问题时，肯定会依循之前学习到的一贯解决方法去搜寻、解答！很重要的！<br /><br />
在这一章里面，我们得要来谈的就是另一个『神功』啦！那就是网路基础。
网路基础真的很重要的，包括乙太网路硬体的了解可以让您知道如何查出有问题的地方，进一步解决他；
了解网路协定(IP)与路由(route)让您可以完整的设定好您的网路架构，更可进一步进行子网路的划分，
以建立更小而美的网路环境！当然还有不可不提的 OSI 网路七层协定，真是重要啊！
不过，在这一章鸟哥以较为口语的方式来介绍这些基础网路架构，希望能带给朋友们快速了解网路是啥。
当然，想要更了解网路相关功能的话，文末的参考资料可以参考看看喔！ ^_^
