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

近十年來，隨著社會科技，文化和經(jīng)濟的發(fā)展，特別是計算機網(wǎng)絡(luò)技術(shù)和通信技術(shù)的大發(fā)展，隨著人類社會從工業(yè)社會向信息社會過渡的趨勢越來越明顯，人們對信息的意識，對開發(fā)和使用信息資源的重視越來越加強，使聯(lián)入這兩個網(wǎng)絡(luò)的主機和用戶數(shù)目急劇增加。

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

未來的因特網(wǎng)不僅具有許多奇特的功能，還可以自動報警。當(dāng)你家有小偷潛入時，未來的因特網(wǎng)就會立即做出反應(yīng)，發(fā)出震耳欲聾的響聲，這時候，你就會馬上從睡夢中醒來，讓小偷無法得逞。通過因特網(wǎng)，你可以弄清楚已經(jīng)過去了的五萬年的歷史，卻不一定能夠知道未來五十年的事情。但有一點是可以肯定的：因特網(wǎng)會越來越 “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). 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.
