Today, the Internet is best described as a network of computers spread across the world, making use of fibre optic cables, telephone lines and satellites to communicate with other computers in the network. The Internet makes use of vacant bandwidth in the telecommunications network to send messages from computer to computer, rather than relying on an entirely new infrastructure.

A standardised addressing system identifies specific computers, making it easy for other computers to hold information about what information other computers are storing and where they are. When we make use of the World Wide Web we are using this addressing system to go to a specific computer, either in Melbourne or possibly on the other side of the world, to read files stored on that computer. While any computer is connected to the network it is described as a ＂node＂ on the Internet, and with appropriate software we can use even a desktop computer to ＂serve＂ files to the rest of the world. It is the simplicity of this networking which has caused it to seize the imagination of users and to grow exponentially.

The Internet, and particularly the World Wide Web, has revolutionised the way we communicate. It is likely that fax machines will go the way of the telegraph and the telex, and while the Internet in ten years will probably look quite different from that which we see now, it is certain to have become even more pervasive.

The most commonly used parts of the Internet today include email, newsgroups, File Transfer Protocol, Internet Relay Chat, and of course the World Wide Web. Other areas which are rapidly growing include Internet telephony and video conferencing.

The Internet The Intemet was first established in 1960s. At that time, the computer was both large and expensive and the networks were unable to work well. If one of the computers broke down, the whole networks would be unable to work. At first, the Intemet was just used by the government. By 1970s, it had been used in universities, banks and hospitals. At the beginning of 1990s, computers became both cheaper and easier to operate. Now it is very convenient to log on the Internet. It is said that each day tens of millions of people log on the Internet.Sending e-mails is becoming more and more popular. The Internet has become the most important part of people's life. 互联网互联网建于20世纪60年代。那时，计算机又大又贵，网络不能很好地运行。如莱其中一台机器出现故障，整个网络就不能运行。起初，互联网只由政府使用。到20世纪70年代，计算机已经被用于大学、银行和医院。

在20世纪90年代初计算机价格下降，也更便于使用了。现在上网很方便。据说每天有成千上万的人上网，发电子邮件正变得越来越流行。互联网已成为许多人生活中最重要的一部分。

INTERNET英语演讲

Internet Civilization Good afternoon, ladies and gentleman! First I want to say is that I'm very proud of to be invited to to present my topic here, which is “ Internet Civilization”. Before I begin my topic, please allow me to ask you a question: Every time you click the mouse to surf the web, do you know what does it mean? On the net, you can make friends overseas and call them with IP phones; you can get information from all over the world; you can even give a hand to some people in troubles and get help when in need. However, we have to admit that internet also leads to intimacy before acquaintance; it scatters secrets outwards, not inwards; and, most worrying of all, it is a vehicle for liars. Here we should see, there exists good and evil, right and wrong on the web. As netizens, we'd better grow to realize the importance of Internet Civilization. Just as the famous saying goes “Long and steep is the path to virtue.” Many people advocate that we should be sincere, honest and responsible in our society—the real world. Now, what I want to add is that we also should obey the primary moral principles in this virtual world. All of my dear friends here, on the internet, which role did you play? Which role are you playing? And which role will you play? Thank you very much!

The Internet is a global system of interconnected computer networks that use the standardized Internet Protocol Suite (TCP/IP) to serve billions of users worldwide. It is a network of networks that consists of millions of private and public, academic, business, and government networks of local to global scope that are linked by copper wires, fiber-optic cables, wireless connections, and other technologies. The Internet carries a vast array of information resources and services, most notably the inter-linked hypertext documents of the World Wide Web (WWW) and the infrastructure to support electronic mail. In addition it supports popular services such as online chat, file transfer and file sharing, gaming, commerce, social networking, publishing, video on demand, and teleconferencing and telecommunications. Voice over Internet Protocol (VoIP) applications allow person-to-person communication via voice and video. The origins of the Internet reach back to the 1960s when the United States funded research projects of its military agencies to build robust, fault-tolerant and distributed computer networks. This research and a period of civilian funding of a new U.S. backbone by the National Science Foundation spawned worldwide participation in the development of new networking technologies and led to the commercialization of an international network in the mid 1990s, and resulted in the following popularization of countless applications in virtually every aspect of modern human life. As of 2009, an estimated quarter of Earth's population uses the services of the Internet.
