我想找一篇关于网络的英语演讲稿,4分钟左右,急用!
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.
