The Internet is an international collection of computer networks that all understand a standard system of addresses and commands, connected together through backbone systems. It was started in 1969, when the U. S. Department of Defence established a nationwide network to connect a handful of universities and contractors. The original idea was to increase computing capacity that could be shared by users in many locations and to find out what it would take for computer networks to survive a nuclear war or other disaster by providing multiple paths between users. People on the ARPNET (as this nationwide network was originally called) quickly discovered that they could exchange messages and conduct electronic “conferences” with distant colleagues for purposes that had nothing to do with the military industrial complex. If somebody else had something interesting stored on their computer, it was a simple matter to obtain a copy (assuming the owner did not protect it).
互联网是计算机网络的国际集合，它们都理解通过骨干系统连接在一起的地址和命令的标准系统。它始于1969年，当时美国国防部建立了一个全国性的网络来连接少数几所大学和承包商。最初的想法是增加计算能力，使许多地方的用户能够共享计算能力，并通过提供用户之间的多条路径，找出计算机网络在核战争或其他灾难中存活的条件。Arpnet（这个全国性网络最初的名称）上的人很快发现，他们可以与远方的同事交换信息和举行电子“会议”，其目的与军事工业综合体无关。如果其他人在他们的计算机上存储了一些有趣的东西，那么获得一个副本就是一件简单的事情（假设所有者没有保护它）。
The Internet is a giant network of computers located all over the world that communicate with each other.
互联网是一个巨大的计算机网络，位于世界各地，相互通信。
Over the years, additional networks joined which added access to more and more computers. Today thousands of networks and millions of computers are connected to the Internet. It is growing so quickly that nobody can say exactly how many users “On the Net”.
随着时间的推移，越来越多的网络加入进来，为越来越多的计算机增加了访问权限。今天，数以千计的网络和数以百万计的计算机连接到互联网上。它的增长速度如此之快，以至于没有人能准确地说出有多少用户“在网上”。
The goal of your use of the Internet is exchanging messages or obtaining information. What you need to know is that you can exchange message with other computers on the Internet and use your computer as a remote terminal on distant computers. But the internal details of the link are less important, as long as it works. If you connect computers together on a network, each computer must have a unique address, which could be either a word or a number. For example, the address of Sam’s computer could be Sam, or a number.
使用互联网的目的是交换信息或获取信息。你需要知道的是，你可以在互联网上与其他计算机交换信息，并使用你的计算机作为远程计算机终端。但是，只要这种联系有效，其内部细节就不那么重要了。如果您将计算机连接到一个网络上，每台计算机必须有一个唯一的地址，可以是一个字或一个数字。例如，Sam电脑的地址可以是Sam，也可以是一个数字。
The Internet is the largest repository of information which can provide very very large network resources. The network resources can be divided into network facilities resources and network information resources. The network facilities resources provide us with the ability of remote computation and communication. The network information resources provides us with all kinds of information services, such as science, education, business, history, law, art and entertainment, etc.
因特网是最大的信息储存库，可以提供非常非常大的网络资源。网络资源可分为网络设施资源和网络信息资源。网络设备资源为我们提供了远程计算和通信的能力。这个网络信息资源为我们提供了科学、教育、商业、历史、法律、艺术、娱乐等各种信息服务。
The Internet is a huge interconnected system, but it uses just a handful of method to move data around. Until the recent explosion of public interest in the Internet, the vast majority of the computers on the Net use the Unix operating system. As a result, the standard Unix commands for certain Internet services have entered the online community’s languages as both nouns and verbs to describe the services themselves. Some of the services that the Internet can provide are: Mail, Remote Use of Another Computer (Telnet), File Transfer, News, and Live Conversation.
互联网是一个巨大的相互连接的系统，但是它只使用了少量的方法来移动数据。直到最近公众对互联网的兴趣激增之前，网上绝大多数计算机都使用Unix操作系统。因此，某些互联网服务的标准Unix命令已经作为名词和动词进入在线社区的语言来描述服务本身。互联网可以提供的一些服务有：邮件、远程使用另一台计算机（Telnet）、文件传输、新闻和实时对话。
The simplest way to access a file on another host is to copy it across the network to your local host. FTP (File Transfer Protocol) can do this.
访问另一台主机上的文件的最简单方法是通过网络将其复制到本地主机。Ftp（文件传输协议）可以做到这一点。
The most commonly used network service is electronic mail (E-mail), or simply as mail. Mail permits network users to send textual messages to each other. Computers and networks handle delivering the mail, so that communicating mail users do not have to handle details of delivery, and do not have to be present at the same time or place.
最常用的网络服务是电子邮件，或简称为邮件。邮件允许网络用户相互发送文本消息。计算机和网络负责传递邮件，这样通信邮件用户就不必处理传递的细节，也不必在同一时间或同一地点出现。
Before you can use the Internet, you must choose a way to move data between the Internet and your PC. This link may be a high-speed data communication circuit, a local area network (LAN), a telephone line or a radio channel. Most likely, you will use a Modem attached to your telephone line to talk to the Internet. Naturally, the quality of your Internet connection and service, like many other things in life, is dictated by the amount of money that you are willing to spend.
在你使用互联网之前，你必须选择一种在互联网和你的电脑之间移动数据的方式。该链路可以是一个高速数据通信电路局域网、电话线或无线电频道。最有可能的是，你将使用一个调制解调器连接到你的电话线上与互联网通话。当然，你的互联网连接和服务的质量，就像生活中的许多其他事情一样，取决于你愿意花多少钱。
Although all these services can well satisfy the needs of the users for information exchange, a definite requirement is needed for the users. Not only should the users know where the resources locate, but also he should know some operating commands concerned to ease the searching burden of the users, recently some convenient searching tools appear, such as Gopher, World Wide Web (WWW) and Netscape.
虽然所有这些服务都能很好地满足用户的信息交换需求，但用户需要一个明确的要求。用户不仅要知道资源所在的位置，还要知道一些相关的操作命令，以减轻用户的搜索负担，最近出现了一些方便的搜索工具，如Gopher、WorldWideWeb（WWW）和Netscape。
Presently, a user with an account on any Internet machine can establish a live connection to any other machine on the Net from the terminal in his own office or laboratory. It is only necessary to use the Unix command that sets up a remote terminal connection (Telnet), followed by the address of the distant machine.
目前，在任何Internet机器上拥有帐户的用户都可以从自己办公室或实验室的终端与网络上的任何其他机器建立实时连接。只需要使用设置远程终端连接（Telnet）的Unix命令，然后是远程计算机的地址。
WWW is a networked hypertext protocol and user interface. It provides access to multiple services anddocuments like Gopher does but is more ambitious in its method. A jump to other Internet service can be triggered by a mouse click on a “hot-linked” word, image, or icon on the web page. As more and more systems join the Internet, and as more and more forms of information can be converted to digital form, the amount of stuff available to Internet users continues to grow. At some points very soon after the nationwide (and later worldwide) Internet started to grow, people began to treat the Net as a community, with its own tradition and customs. For example, somebody would ask a question in a conference, and a complete stranger would send back an answer: after the same question were repeated several time by people who hadn’t seen the original answers, somebody else gathered list of “frequently asked questions” and placed it where newcomers could find it.
是一个联网的超文本协议和用户界面。它提供了多种服务和文档的访问，就像Gopher所做的那样，但是它的方法更加雄心勃勃。跳转到其他互联网服务可以被触发。通过鼠标点击网页上的“热链接”单词、图像或图标。随着越来越多的系统加入互联网，随着越来越多的信息可以转化为数字形式，互联网用户可用的东西数量继续增长。在某些时候，全国范围内（和后来世界范围内）互联网开始发展，人们开始把网络当作一个社区，有自己的传统和习俗。例如，有人在一次会议上提出一个问题，一个完全陌生的人会发回一个答案：在同一个问题被没有看到原始答案的人重复了几次之后，另一个人收集了一系列“常见问题”，并将其放置在新人可以找到它。
So we can say that the Internet is your PC’s window to the rest of the world.
所以我们可以说，互联网是你的电脑通向世界其他地方的窗口。
