计算机因特网双语阅读 VIEW OF THE INTERNET INTERNET The Internet is a worldwide network of networks which interconnects computers ranging from the simplest personal computers to the most sophisticated mainframes and supercomputers. This network of networks is used for an extraordinary range of purposes - long distance collaborations, retrieving free software and documents, accessing library catalogs, logging in to supercomputers - the list of current Internet activities and services is large and the range of possible future applications is as unlimited as our imagination.

The Internet is huge. No one is exactly sure just how huge, but there are over two million connected computers[1]. Because it is in direct communication with satellites far above us, it could even be said that the Internet is already bigger than the Earth. And because the Internet is incredibly complex, there probably isn't a single person who understands everything about it. Remember this if you get confused and you'll probably feel better！

WHAT IS AN "INTERNET" An internet （note the lower case "i"） is a computer network which allows computers with distinctive software and hardware to communicate, or "internetwork"[2]. Many kinds of computers can be connected to an internet, and each computer can serve a specialized role, allowing an internet to offer a wide variety of services to its users. For example, you could use one internet computer designed to perform complex calculations and then send the output to another internet computer designed to display colorful graphs.

WHAT IS "THE INTERNET" The Internet is specific kind of internet. In The Internet Passport, the Internet will be defined as the network of networks which follow a set of rules known as the "Internet Protocol （IP） suite".

But what does this mean to you？ It means that any computer which is connected to the Internet can communicate with any other Internet computer thanks to the rules of IP, and that a message sent from one Internet computer to another will get to the intended destination[3]. From the user's perspective, this works much the way the telephone system works. You can dial from your phone to any other phone on the system no matter what kind of telephone you have； you only need to know the phone number of the person you want to reach.

WHAT IS THE INTERNET USED FOR The Internet contains the electronic equivalents of conference rooms and cafes, libraries and bookstores, post offices and telephones, radio and television stations, newspaper and magazines, and a growing variety of services that have no counterparts in "the real world"[4].

Accessing Computer Resources No matter how humble your own computer might be, if it is connected to the Internet you can access the resources of thousands of computers throughout the world. With an Internet connection you can：

access online library catalogs, w copy computer files or software from archives[5],

access databases for teaching or research, w obtain free electronic books,

use educational and information services, use directory services to find Internet users, and access supercomputer sites. Although the Internet is made up of many diverse computers, together they work like one world-wide computer system.

Communicating with Other People People communicating with people is the essence of the Internet. Using the Internet you can：

exchange electronic mail, find people throughout the world who share your interests, and engage in discussions and collaborations with other Internet users. These services have created a truly global village where people communicate with each other not because they happen to live in the same place, but because they share the same interests. This simple fact has profound consequences for everyone no matter where they live.

NOTES [1] 这是1996年的数字。 [2] internet是指互联网，internetwork是指网间互连，但二者可以混用。 [3] 两个that均引导宾语从句。It means that„„.,and that„„„是并列关系。

[4] 此处contains是转意为支持各种电子设备连入因特网，但必须通过计算机接入。

[5] archives指计算机挡案库存储器。 因特网概貌 因特网 因特网是一个世界规模的由多个网络连接而成的网络，它所连接的计算机小到最简单的个人电脑，大到最复杂的计算机和超级计算机。该网络的应用范围也特别广—— 远距离合作、检索免费软件和文档、查阅图书馆目录、登录到超级计算机上——目前因特网的功能和业务范围十分广泛，而今后的应用前景正如我们想象的那样是无止境的。

因特网非常巨大。无人能够准确地说出它有多大，联网计算机已超过两百万台。因为它直接通过远离我们的卫星通信，因而甚至可以说因特网已经比地球还大了。又因为因特网不可思议的复杂，因而很可能没有一个人能对因特网无所不晓。请记住，如果你糊涂了，那你可能会感觉更好。

什么是互联网 互联网（注意小写字母i）是一种计算机网络，该网络上的计算机在通信时可以使用不同的软件和硬件。多种计算机都可以连入互联网，每台计算机都可以有一独特作用，于是一个互联网就可以向它的用户提供各式各样的业务。例如，可以用互联网上的一台计算机去完成复杂的计算任务，然后将结果送到另一台计算机以显示彩色图形。

The issue of computer security first arose in the 1970s as individuals began to break into telephone systems. As technologyadvanced, computer systems became targets as well. The Federal Bureau of Investigation (FBI 1) made one of its first arrests related to computer hacking in the early 1980s.When talking about computer security, some people think firstly of their credit card numbers, social security numbers 2, and other personal information. Knowing how to protect private information from those who would exploit it is very important. However, that is only one part of computer security. Computer security in a broad sense consists of the three aspects: hardware security, information security and administration security.Ⅰ. Hardware security falls into physical security and emanation security 3. The former concerns protection of computer hardware and associated equipments, such as computers, servers, networks and peripheral equipment, etc. from external physical threats, such as tampering , theft, earthquakes, water, etc. The latter copes with protection against spurious signals 4 emitted by electrical equipments in the system, such as electromagnetic emission from displays and audio emission (sounds from printers, etc).Ⅱ.

精心收集了有关计算机英文文章，供大家欣赏学习!有关计算机英文文章篇1电脑的利弊 The Pros and Cons of ComputerComputer is increasingly popular in people’s daily life. The number of computer in every family is more than TV set. Some people think it is so great that they all regard it as a gift from the heaven. However, some people consider it brings more disadvantages than advantages. In my opinion, both opinions are correct, but if we can use computer in a proper way, its advantages are superior to disadvantages. I have several reasons.在人们的日常生活中电脑越来越受欢迎。

每家每户拥有电脑的数量要比电视机多。

有些人觉得电脑真的很棒，所以他们都把他当作是上天赐予他们的礼物。

然而，有些人则认为它所带来的弊端要比好处多。

在我看来，这两个观点是正确的，但如果我们能够恰当地使用电脑，它的优点是会比缺点多的。

理由有几点。

On the one hand, computer makes human beings’life become easier. People can do many things that they can’t do before. They can read newspaper without buying it, only sitting in front of their computer, clicking mouse to open website. Shopping online, watching movies, listening music and play computer games are the common things that people often do by computer. But without computer, they can’t do all these easily. In addition, computer is also very helpful for study and work. People can have classes and work on it.一方面，电脑使人们的生活变得更容易。
