The TCP/IP Guide: Introduction and "Guide to The Guide" | 第1章 概述和導言

---

---

Chances are pretty good that even before you started reading this Guide, you had heard of "TCP/IP" -- even if you didn't know exactly what it was or even what all those letters stood for. The reason for this is simple: TCP/IP is everywhere! It is today by far the most commonly-used internetworking protocol suite. It has gained prominence in large part due to its role in operating the global Internet, which has in a few short years transformed our society in so many ways. Millions of people use TCP/IP and the Internet without really knowing how they work.  For those in the technology field, however, understanding TCP/IP is becoming more important with each passing year.

好機會呀好機會！即使你從前讀過本書也據說過"TCP/IP"，或者你壓根就不知道TCP/IP這些單詞是神馬意思。緣由異常簡單：TCP/IP無處不在！時至今天，TCP/IP是最爲普及的一種網絡互聯協議套裝。它之因此聲名遠播，得益於它在全球互聯網中所擔當的角色。而互聯網在短短的幾年裏，在許多方面改變了咱們的社會。成千千上萬萬的人在使用TCP/IP， 在使用互聯網，雖然他們並不知道TCP/IP和互聯網的工做原理。然而，對那些技術領域的人們來講，理解TCP/IP顯得愈來愈重要了。(P.S. 不懂TCP/IP, 是否是很丟人？！)

As we journey together through this TCP/IP guide, we will explore many hundreds of pages of material that will explain both the generalities and specifics of TCP/IP in a way that I hope you will find educational and interesting. Before diving into the actual technology, however, I felt that I should provide you with some introductory material to help frame the discussions that follow. Thus, I have included this section, to serve as an introduction to this Guide and to provide some information that will help you use it to its full potential.

咱們即將開始TCP/IP Guide的漫長旅程，數百頁的材料中將涵蓋TCP/IP的概述和必定程度上的細節描述，但願讀者能從中體會到受用且有趣。在一個猛子扎入到實際的技術以前，我感受有必要提供一些介紹性的材料以幫助你們對後續的討論有一個框架性的瞭解。所以，我寫了這一節，對本指南作一個概述並提供一些信息，指望這些信息可以儘量地幫助讀者理解後續的內容。

I begin with some material that will be of interest to those who want to know the background of The TCP/IP Guide. I provide a general introduction to the Guide, describing its history, and how it came about. I then describe the goals of this Guide and what I was trying to accomplish in writing it. I also discuss the scrope of the Guide, so you know what it covers and what it does not.

在這裏，咱們從那些想了解TCP/IP指南的背景的人感興趣的材料開始。首先，我將給你們提供一個有關這一Guide的概述，並描述其歷史和說明它是怎麼來的。而後，我將描述一下這個Guide的目標和我打算寫什麼。最後，將討論一下這一Guide涉及的範圍，說清楚哪些內容將被涵蓋到，哪些內容將不被談及。

The rest of the section contains more practical information to help you best utilize this rather large document. I explain how the Guide is structured and organized, and discuss its special features. I then provide some specific tips to help you navigate the Guide using the Adobe Acrobat Reader software you are likely using at this moment. :-) I also explain how you can provide feedback on the Guide and suggestions for improving it, and I conclude with a summary of the Guide's version history.

本節的其它部分包含了一些更具實踐性的信息，能夠幫助讀者更好地利用本書（巨型文檔）。我將介紹本Guide的組織結構和討論其特色。接下來我將提供一些具體的建議以幫助讀者使用Adobe Acrobat Reader來瀏覽本Guide, 也許你正在使用Adobe的閱讀器。 :-) 我還將解釋如何提供關於本指南的反饋和改進建議，最後我將給出一個有關本指南版本歷史的總結。

Note: There is no actual technical content in this section. If you are the type who buys something and starts using it right away without cracking open the manual, you may want to skip this section. If so, you should start by looking at the high-level discussion of the TCP/IP protocol suite; alternately, you may wish to begin at the Networking Fundamentals section or with a look at the OSI Reference Model. However, I do recommend at least skimming the topics in this section before you move on, especially the topics discussing the structure and organization of the Guide and its features. This will make the rest of the Guide easier to understand and probably save you time in the long run.

注： 本節並無實際的技術內容。若是你是那種買了東西就理解使用（不拆開使用手冊）的人，你確定想跳過本節。若是是這樣，請先看看TCP/IP協議套裝的高級別的討論；或者從網絡基礎部分開始，或者看看OSI參考模型。不過，我強烈建議您至少先略讀一下本節中的主題，尤爲是討論本指南的結構、組織及特性的主題。這將使本指南的其他部分理解起來更容易，並極可能會節省您的時間，從長遠的角度看的話。
