CCNA 学习指南（英文版）（640-801） (2008 年度畅销榜NO.3308 )

世界著名的网络系统公司Cisco公司建立于20世纪80年代，主要致力于开发、生产、销售高档网关、路由器和网络互联设备，其产品广泛应用于局域网、广域网和因特网。在微软公司一方独大的互联网络世界中，Cisco却是路由和交换领域真正的无冕之王。由于Cisco公司的产品不同于普通的计算机软、硬件产品，它的技术含量高，原理复杂，因此学习和掌握其工作原理及使用方法需要许多相关知识和实践经验。为保证使用、管理或提供Cisco产品服务的技术人员能够具备相应的技术水平，Cisco公司设立了一系列认证考试，不仅如此，其考试目标和内容也随其产品不断地发生变化。为覆盖其最新的考试目标，我们采用“原版引进，重新排版印刷”的方式以最快的速度出版Cisco认证考试系列相应科目的辅导丛书来满足读者的需求。本书作为系列中的一本，针对CCNA：640-801考试而推出。书中的内容从联网和TCP/IP的背景开始介绍，接着介绍了子网划分、Cisco网络操作系统和命令行界面，然后讲述了路由和交换，最后介绍了VLAN和WAN等内容。\r\n
