Internet是一組全球信息資源的總匯。有一種粗略的說(shuō)法，認(rèn)為Internet是由于許多小的網(wǎng)絡(luò)（子網(wǎng)）互聯(lián)而成的一個(gè)邏輯網(wǎng)，每個(gè)子網(wǎng)中連接著若干臺(tái)計(jì)算機(jī)（主機(jī)）。Internet以相互交流信息資源為目的，基于一些共同的協(xié)議，并通過(guò)許多路由器和公共互聯(lián)網(wǎng)組成，它是一個(gè)信息資源和資源共享的集合。計(jì)算機(jī)網(wǎng)絡(luò)只是傳播信息的載體，而Internet的優(yōu)越性和實(shí)用性則在于它本身。

近十年來(lái)，隨著社會(huì)科技，文化和經(jīng)濟(jì)的發(fā)展，特別是計(jì)算機(jī)網(wǎng)絡(luò)技術(shù)和通信技術(shù)的大發(fā)展，隨著人類社會(huì)從工業(yè)社會(huì)向信息社會(huì)過(guò)渡的趨勢(shì)越來(lái)越明顯，人們對(duì)信息的意識(shí)，對(duì)開(kāi)發(fā)和使用信息資源的重視越來(lái)越加強(qiáng)，使聯(lián)入這兩個(gè)網(wǎng)絡(luò)的主機(jī)和用戶數(shù)目急劇增加。

從目前的情況來(lái)看，Internet市場(chǎng)仍具有巨大的發(fā)展?jié)摿Γ鋺?yīng)用涵蓋從辦公室共享信息到市場(chǎng)營(yíng)銷、服務(wù)等廣泛領(lǐng)域。另外，Internet帶來(lái)的電子貿(mào)易正改變著現(xiàn)今商業(yè)活動(dòng)的傳統(tǒng)模式，其提供的方便而廣泛的互連必將對(duì)未來(lái)社會(huì)生活的各個(gè)方面帶來(lái)影響。

未來(lái)的因特網(wǎng)不僅具有許多奇特的功能，還可以自動(dòng)報(bào)警。當(dāng)你家有小偷潛入時(shí)，未來(lái)的因特網(wǎng)就會(huì)立即做出反應(yīng)，發(fā)出震耳欲聾的響聲，這時(shí)候，你就會(huì)馬上從睡夢(mèng)中醒來(lái)，讓小偷無(wú)法得逞。通過(guò)因特網(wǎng)，你可以弄清楚已經(jīng)過(guò)去了的五萬(wàn)年的歷史，卻不一定能夠知道未來(lái)五十年的事情。但有一點(diǎn)是可以肯定的：因特網(wǎng)會(huì)越來(lái)越 “神”。

拓展閱讀：

With the development of science(科學(xué)) and technology(技術(shù)), more and more people are communicating with each other by e-mails. People are "talking" through computers. No matter how far away they are from each other, they can always communicate with each other readily. Sending emails has become an important way of communicating between people.

No doubt, email has a great deal of advantages(優(yōu)點(diǎn)). The most important one is that sending emails is so fast that we needn't wait for a long time to get the message we want. We can exchange our feelings and ideas easily. And we can get a great amount of written information in no time. And compared with talking on the phone, sending emails can be much more economical, especially than making long-distance phone calls. Of course, convenience is also a merit. It's too troublesome(麻煩) to go to the post office to send a letter. As long as you have an email box and a computer, you can send an email anytime.

Nowadays, when more and more people have a computer and know how to send and receive emails through computers, communication emails is very fashionable. I am sure it will become the most popular way for people to keep in touch with each other in the near future.
