Computer Networking A Top Down Approach

這本書專為計算機網路的入門課程而設計。內容上的編排假設讀者已有基本的 C、C++、Java 或 Python 程式語言經驗（即便如此，僅在少數部分會涉及程式設計）。與其他計算機網路的基礎教科書相比，本書更具嚴謹性與分析深度，但特別設計為僅需高中程度的數學基礎。避免了進階微積分、機率或隨機程序的概念（但提供進階習題，供有需要的讀者挑戰）。因此，本書適合用於大學或研究所第一年的「電腦網路」或「計算機網路」課程，同時對電信業界的專業人士也有極大的實用價值。

本書是經典的計算機網絡教材之一，採用了作者獨創的自頂向下方法來講授計算機網絡的原理及其協議，自16年前第1版出版以來已經被數百所大學和學院選作教材，被譯為14種語言。第7版保持了以前版本的特色，繼續關注因特網和計算機網絡的現代處理方式，注重原理和實踐，為計算機網絡教學提供了一種新穎和與時俱進的方法。同時，第7版進行了相當多的修訂和更新，首次改變了各章的組織結構，將網絡層分成兩章（第4章關注網絡層的

This new networking text follows a top-down approach. The presentation begins with an explanation of the application layer, which makes it easier for students to understand how network devices work,

A top-down,layered approach to computer networking. Unique among computernetworking texts, the 8th Edition, Global Edition, of thepopular Computer Networking: A Top Down Approach buildson the authors' long tradition of teaching this complex subject through alayered approach in a "top-down manner." The text works its way from theapplication layer down toward the physical layer, motivating students byexposing them to important concepts early in their study of networking.Focusing on the Internet and the fundamentally important issues of networking,this text provides an excellent foundation for students in computer science andelectrical engineering, without requiring extensive knowledge of programming ormathematics. The 8th Edition, Global Edition, has been updatedto reflect the most important and exciting recent advances in networking,including the importance of software-defined networking (SDN) and the rapidadoption of 4G/5G networks and the mobile applications they enable.Chapter 1:Comp
