What is the Internet?

The Internet is a worldwide network, linking computers to computers. Each computer runs software to provide or ‘serve’ information, or to access and view information. The Internet transports the information — like a giant plumbing system.

Computers on the Internet can use:

l         electronic mail (email). This allows you to send and receive mail with other computer users.

l         the World Wide Web (WWW). Through the WWW you can view images, look at film clips, hear sound recordings and find information on many interests.

This information is stored on websites.

On the Internet, you can access information stored on other computers, or jump from one page of information to another. Each page has its own address showing its location, just like your home address.

What do you need to use the Internet?

l         A connection to an Internet Service Provider (or ISP). The most commonly used method is across a telephone line with a modem (preferably a fast one).

l         Internet software, e.g. Internet Explorer, provided by your ISP — usually called a ‘browser’.

How does email work?

First, you need an email address. It could look something like this:

Daniel.jones@ozemail.com.au

     If someone sends Daniel an email, the message is received by Daniel’s ISP and waits there till the next time he connects to the Internet. When he connects (that is called logging on) his message is sent down the telephone line to his modem and onto his email program.

     How do you send email?

     It’s a bit like sending a letter. You need to know the email address of the person who’s receiving your letter.

     Type in that person’s email address in the ‘To’ box and type your message. When you’ve finished, click on ‘Send’.

     If someone has already sent you a message, you can just click on ‘Reply’ and type your message. It’s as easy as that.

     Some Internet Codes

     .com  commercial institutions

     .edu  educational institutions

.gov  government institutions

.net  networks

Country Codes

.au  Australia

.jp  Japan

.nz  New Zealand

Email addresses in the USA have no country code, because the Internet originated(起源于) there. For example, the Internet address for Expert Software (made in the USA) is www.expertsoftware.com.

93.   What does ISP stand for(代表)?

94.   WWW can help us look at film clips and find information as well, can’t it?

95.   Where is the information stored?

96.  If your friend sent you an email, what would be the quickest way to send one back?

97.  Why do email addresses in the USA have no country code?

98.  What’s your favourite website? Why?

What might the future be like? Here are some predictions: things to come, things to go.
The Spring Festival, the most important Chinese holiday when everyone returns home, has caused headaches for millions of Chinese. More than 2 billion people travel at the same time, making getting travel tickets and the journey difficult. But in 28 years, Spring Festival travel may not be a problem at all. China plans to build more than 120,000 kilometers of railway and a fast transportation network that will serve 90% of the population by 2020. And because most of China will be cities, people will not have to go to other places to find a job, so it will no longer be a problem.
Newspaper will come to an end in 2043. In the future, digital(数字的) newspapers will be sent to personal web tools through Internet. Readers can discuss topics with journalists and editors. Information will move faster.
Oil is running out faster than expected. But scientists have found something else for oil as fuel(燃料). Coal, natural gas, solar power, nuclear power and even water can take the place of oil as sources of energy(能源).
Schools will go electronic(电子化). Computers will be important and popular among the students. Everything will be in the computer and students will not need to bring books to school. They will find information on the Internet. A computer will be the students’ library, schoolbag and connection to the outside world. There will be robot teachers, they will check homework on computers and communicate with the students’ parents through e-mail. And school buses will be like spaceships, comfortable and safe.
