　　英語(yǔ)現(xiàn)在在我們的生活已經(jīng)是無(wú)處不見(jiàn)了，所以大家要好好學(xué)習(xí)一下，所以小編今天就給大家整理了有關(guān)于計(jì)算機(jī)的英語(yǔ)，大家可以閱讀一下哦

　　計(jì)算機(jī)英語(yǔ)

　　INTERNET

　　The Internet is a worldwide network of networks which interconnects computers ranging from the simplest personal computers to the most sophisticated mainframes and supercomputers. This network of networks is used for an extraordinary range of purposes - long distance collaborations, retrieving free software and documents, accessing library catalogs, logging in to supercomputers - the list of current Internet activities and services is large and the range of possible future applications is as unlimited as our imagination.

　　The Internet is huge. No one is exactly sure just how huge, but there are over two million connected computers[1]. Because it is in direct communication with satellites far above us, it could even be said that the Internet is already bigger than the Earth. And because the Internet is incredibly complex, there probably isn't a single person who understands everything about it. Remember this if you get confused and you'll probably feel better!

　　WHAT IS AN "INTERNET"

　　An internet (note the lower case "i") is a computer network which allows computers with distinctive software and hardware to communicate, or "internetwork"[2]. Many kinds of computers can be connected to an internet, and each computer can serve a specialized role, allowing an internet to offer a wide variety of services to its users. For example, you could use one internet computer designed to perform complex calculations and then send the output to another internet computer designed to display colorful graphs.

　　WHAT IS "THE INTERNET"

　　The Internet is specific kind of internet. In The Internet Passport, the Internet will be defined as the network of networks which follow a set of rules known as the "Internet Protocol (IP) suite".

　　But what does this mean to you? It means that any computer which is connected to the Internet can communicate with any other Internet computer thanks to the rules of IP, and that a message sent from one Internet computer to another will get to the intended destination[3]. From the user's perspective, this works much the way the telephone system works. You can dial from your phone to any other phone on the system no matter what kind of telephone you have; you only need to know the phone number of the person you want to reach.

　　WHAT IS THE INTERNET USED FOR

　　The Internet contains the electronic equivalents of conference rooms and cafes, libraries and bookstores, post offices and telephones, radio and television stations, newspaper and magazines, and a growing variety of services that have no counterparts in "the real world"[4].

　　Accessing Computer Resources

　　No matter how humble your own computer might be, if it is connected to the Internet you can access the resources of thousands of computers throughout the world. With an Internet connection you can：

　　access online library catalogs, w copy computer files or software from archives[5],

　　access databases for teaching or research, w obtain free electronic books,

　　use educational and information services,

　　use directory services to find Internet users, and

　　access supercomputer sites.

　　Although the Internet is made up of many diverse computers, together they work like one world-wide computer system.

　　Communicating with Other People

　　People communicating with people is the essence of the Internet. Using the Internet you can：

　　exchange electronic mail,

　　find people throughout the world who share your interests, and

　　engage in discussions and collaborations with other Internet users.

　　These services have created a truly global village where people communicate with each other not because they happen to live in the same place, but because they share the same interests. This simple fact has profound consequences for everyone no matter where they live.

　　NOTES

　　[1] 這是1996年的數(shù)字。

　　[2] internet是指互聯(lián)網(wǎng)，internetwork是指網(wǎng)間互連，但二者可以混用。

　　[3] 兩個(gè)that均引導(dǎo)賓語(yǔ)從句。It means that…….,and that………是并列關(guān)系。

　　[4] 此處contains是轉(zhuǎn)意為支持各種電子設(shè)備連入因特網(wǎng)，但必須通過(guò)計(jì)算機(jī)接入。

　　[5] archives指計(jì)算機(jī)擋案庫(kù)存儲(chǔ)器。

　　因特網(wǎng)概貌

　　因特網(wǎng)

　　因特網(wǎng)是一個(gè)世界規(guī)模的由多個(gè)網(wǎng)絡(luò)連接而成的網(wǎng)絡(luò)，它所連接的計(jì)算機(jī)小到最簡(jiǎn)單的個(gè)人電腦，大到最復(fù)雜的計(jì)算機(jī)和超級(jí)計(jì)算機(jī)。該網(wǎng)絡(luò)的應(yīng)用范圍也特別廣—— 遠(yuǎn)距離合作、檢索免費(fèi)軟件和文檔、查閱圖書館目錄、登錄到超級(jí)計(jì)算機(jī)上——目前因特網(wǎng)的功能和業(yè)務(wù)范圍十分廣泛，而今后的應(yīng)用前景正如我們想象的那樣是無(wú)止境的。

　　因特網(wǎng)非常巨大。無(wú)人能夠準(zhǔn)確地說(shuō)出它有多大，聯(lián)網(wǎng)計(jì)算機(jī)已超過(guò)兩百萬(wàn)臺(tái)。因?yàn)樗苯油ㄟ^(guò)遠(yuǎn)離我們的衛(wèi)星通信，因而甚至可以說(shuō)因特網(wǎng)已經(jīng)比地球還大了。又因?yàn)橐蛱鼐W(wǎng)不可思議的復(fù)雜，因而很可能沒(méi)有一個(gè)人能對(duì)因特網(wǎng)無(wú)所不曉。請(qǐng)記住，如果你糊涂了，那你可能會(huì)感覺(jué)更好。

　　什么是互聯(lián)網(wǎng)

　　互聯(lián)網(wǎng)(注意小寫字母i)是一種計(jì)算機(jī)網(wǎng)絡(luò)，該網(wǎng)絡(luò)上的計(jì)算機(jī)在通信時(shí)可以使用不同的軟件和硬件。多種計(jì)算機(jī)都可以連入互聯(lián)網(wǎng)，每臺(tái)計(jì)算機(jī)都可以有一獨(dú)特作用，于是一個(gè)互聯(lián)網(wǎng)就可以向它的用戶提供各式各樣的業(yè)務(wù)。例如，可以用互聯(lián)網(wǎng)上的一臺(tái)計(jì)算機(jī)去完成復(fù)雜的計(jì)算任務(wù)，然后將結(jié)果送到另一臺(tái)計(jì)算機(jī)以顯示彩色圖形。

　　什么是因特網(wǎng)

　　因特網(wǎng)是一種專用互聯(lián)網(wǎng)。因特網(wǎng)在它的證書中定義為網(wǎng)絡(luò)的網(wǎng)絡(luò)，該網(wǎng)絡(luò)使用了一組叫做互聯(lián)網(wǎng)協(xié)議簇的協(xié)議(IP)。

　　但對(duì)你來(lái)說(shuō)，這意味著什么呢?這表明，由于IP協(xié)議的作用，連接到因特網(wǎng)上的計(jì)算機(jī)可以與因特網(wǎng)上任何其他計(jì)算機(jī)通信，并且從一臺(tái)因特網(wǎng)上的計(jì)算機(jī)送往另一臺(tái)計(jì)算機(jī)上的信息，將到達(dá)指定的目的地。從用戶的角度來(lái)看，其工作方式很像電話系統(tǒng)的工作方式。在電話系統(tǒng)內(nèi)，可以從你的電話機(jī)撥打任何其他電話，而不管你使用什么樣的電話機(jī);你只需知道對(duì)方的電話號(hào)碼即可。

　　因特網(wǎng)的用途

　　因特網(wǎng)包含了會(huì)議室和咖啡屋、圖書館和書店、郵政局和電話局、無(wú)線電臺(tái)和電視臺(tái)、報(bào)社和雜志社的電子業(yè)務(wù)，以及“現(xiàn)實(shí)世界”中還沒(méi)有出現(xiàn)的各種業(yè)務(wù)。

　　訪問(wèn)計(jì)算機(jī)資源

　　不論你的計(jì)算機(jī)檔次如何低，只要你連入因特網(wǎng)，你就可以訪問(wèn)遍及全世界的成千上萬(wàn)臺(tái)計(jì)算機(jī)上的資源。使用因特網(wǎng)，可以：

　　訪問(wèn)在線圖書館目錄

　　從計(jì)算機(jī)檔案庫(kù)存儲(chǔ)器中拷貝文件或軟件

　　訪問(wèn)教學(xué)或科研數(shù)據(jù)庫(kù)

　　獲取免費(fèi)電子圖書

　　使用教育和信息服務(wù)

　　使用目錄服務(wù)以查找因特網(wǎng)用戶

　　訪問(wèn)超級(jí)計(jì)算機(jī)站點(diǎn)

　　雖然因特網(wǎng)是由許多各式各樣的計(jì)算機(jī)組成的，但它們就像是一個(gè)遍布全世界的計(jì)算機(jī)系統(tǒng)一樣一起工作著。
