隨著計算機網絡的發展，本版對相關內容進行瞭大量修訂、更新和補充，具體更新內容如下：
•無綫網絡（802.12和802.16）。
•智能手機使用的3G網絡。
•RFID和傳感器網絡。
•使用CDNs進行內容分發。
•對等網絡。
•實時媒體。
•網絡電話。
•延遲容忍網絡。

在看这本书前我是有计算机网络基础的，本来是抱着复习的态度来看这本书的。但是越看越觉得以前的了解太片面了，这本书真的是像讲故事一样的娓娓道来，每一个协议、算法的提出都是层层递进，先讲需求，再讲实现，不会让你一头雾水的感觉。因为英文阅读比中文慢的原因我之前读的...
評分第一章看完了，讲解的确实详细，不过感觉看的有点累。 后面的物理层首先讲的就是傅立叶级数，伤脑筋啦。物理层、数据链路层、介质访问控制子层、网络层、传输层和应用层，不知道后面是不是很难，要怎么才能看完啊。 这本书竟然比c primer plus（都是入门类书籍~~~）还要厚。 ...
評分大学时的教材里最喜欢的书，没有之一。很少有技术书能让人读的时候像读小说一样不觉得累，同时内容精彩没有啰嗦和废话。大三上这门课时读过一遍，毕业将近5年后又重读了一遍，毕业后积累的很多知识发现书中都有提及到，并且虽然原著作者的写作时间比较早，但书中的内容在互联网...

大師的經典作品就是不一樣，語言幽默風趣，就像是讀故事一般。
评分跟作者辦公室離得近，
评分我現在即將大三～選修瞭這門課～隻是老師講的太淺薄！於是我在圖書館尋尋覓覓～找到瞭最新版的書～雖然是外文書籍～但是看起來並不費勁！看瞭前幾章～內容講的通俗易懂！我決定用大三上的整個時光好好研究它！同是齣自作者的另外一本書，計算機操作係統～講的也很好！主要講解的是mini的linux內核隻有3000多行～是學習操作係統的好東西！最後～感覺能在學校裏遇到這兩本書實乃我的榮幸！
评分新版加上瞭智能手機使用的3G網絡,關注
评分我認為是本挺槽糕的教科書。網絡技術本身比較抽象的，因此需要作者自身的理論紮實與寫作功底。在對待新手而言，還是日本人更幽默與友善，推薦那本《網絡是怎樣連接的》。
