三、英譯漢(本大題共10小題)
1、AnotherelectromechanicalcomputingmachinewasdevelopedbyHowardAiken,withfinancialassistance
fromIBM,atHarvardUniversityin1943.ItwascalledtheAutomaticSequenceControlCalculatorMarkI,or
simplytheHarvardMarkI.Neitherofthesemachineswasatruecomputer,however,becausetheywerenot
entirelyelectronic.
答案:另一臺(tái)機(jī)電式計(jì)算機(jī)器是由霍華德.艾坎在IBM的資助下于1943年在哈佛大學(xué)研制的。它被稱為自
動(dòng),字列控制計(jì)算器MarkI,或簡(jiǎn)稱哈佛MarkI。然而,這些機(jī)器都不是真正的計(jì)算機(jī),因?yàn)樗鼈儾煌耆?/p>
電子化的。
2、Perhapsthemostinfluentialoftheearlycomputerlikedeviceswas(heElectronicNumericalIntegratorand
Computer,orENIAC.ItwasdevelopedbyJ.PresperEckerlandJohnMauchlyattheUniversityofPennsylvania.
答案:也許早期最具影響力的類似計(jì)算機(jī)的裝置應(yīng)該是電子數(shù)字積分計(jì)算機(jī),或簡(jiǎn)稱ENIAC。它是由賓夕
凡尼亞大學(xué)的J.PresperEckert和JohnMauchly研制的。
3、Itwasnotcompleted,however,until1951.BeforetheEDVACwasfinished,severalothermachineswerebuilt
thatincorporatedelementsoftheEDVACdesignofEckert,Mauchly,andvonNeuman.OnewastheElectronic
DelayStorageAutomaticComputer,orEDSAC,whichwasdevelopedinCambridge,England.
答案:然而,直到1951年,它才得以完成。在EDVAC完成之前,其他一些機(jī)器造好了,它們吸收了Eckert>
Mauchly和Neuman的EDVAC設(shè)計(jì)要素。其中一部是在英國(guó)劍橋研制的電子延遲存儲(chǔ)自動(dòng)計(jì)算機(jī),或簡(jiǎn)稱
EDSACo
4、TheUNIVACIwasthefirstcommercialcomputerinthisgeneration.Asnotedearlier,itwasusedintheCensus
Bureauin1951.Itwasalsothefirstcomputertobeusedinabusinessapplication.In1954,GeneralElectrictook
deliveryofaUNIVACIanduseditforsomeofitsbusinessdataprocessing.
答案:UNIVACI是第一代中最早的商業(yè)化計(jì)算機(jī)。如前所述,它在1951年被用于人口普查局。它還是第
一部用于商'業(yè)應(yīng)用的計(jì)算機(jī)。在1954年,通用電氣接收了UNIVACI,并用它進(jìn)行一些商'業(yè)數(shù)據(jù)處理。
5、NetworkStructures.Unlikethetreeapproach,whichdoesnotpermittheconnectionofbranches,thenetwork
structurepermitstheconnectionofthenodesinamultidirectionalmanner.
答案:網(wǎng)狀結(jié)構(gòu)。網(wǎng)狀結(jié)構(gòu)不像樹型結(jié)構(gòu)那樣不允許樹枝相連,它允許節(jié)點(diǎn)間多個(gè)方向連接。

spreadquicklythroughoutaharddiskoranentireorganizationwhenitinfectsaLANoramulti-usersystem.At
somepoint,itisdeterminedbyhowtheviruswasprogrammedthevirusattacks.
答案:病毒程序一旦附加到一個(gè)主程序上,就開始尋找其他可以進(jìn)行“感染”的程序。這樣,如果病毒感
染了一個(gè)局域網(wǎng)或者一個(gè)多用戶系統(tǒng),那么它就在整個(gè)硬盤或整個(gè)組織內(nèi)迅速擴(kuò)散。只有在某個(gè)點(diǎn)上病毒
程序才會(huì)發(fā)作。
7、N,whichwasestablishedtoaidInternetusersinfindingandsharingonlinemusicfilesknownas

答案:Napster,com建立的目標(biāo)是幫助因特網(wǎng)用戶發(fā)現(xiàn)并分享在線音樂文件,即人所共知的MP3文件。盡
管純粹論者強(qiáng)調(diào):因?yàn)樗蕾囍醒霐?shù)據(jù)庫來顯示哪一位用戶正在分享音樂文件,所以Napsler僅僅是部分
對(duì)等。但Napster或許是對(duì)等電子商務(wù)最著名的實(shí)例。
8、C++canbeviewedasatraditionalprocedurallanguagewithsomeadditionalconstructs.BegiiningwithC,
someconstructsareaddedforobjectorientedprogrammingandsomeforimprovedproceduralsyntax.Awell
writtenC++programwillreflectelementsofbothanobjectorientedprogrammingstyleandaclassicprocedural
programming.
答案:C++被看作在傳統(tǒng)過程語言的基礎(chǔ)上補(bǔ)充了一些結(jié)構(gòu)。以C語言為基礎(chǔ),有些結(jié)構(gòu)是為了面向?qū)ο?/p>
的程序設(shè)計(jì)而添加的,有些則是為了改進(jìn)過程語法。一個(gè)好的,++程序應(yīng)考慮面向?qū)ο蟮某绦蛟O(shè)計(jì)風(fēng)格和
古典的過程程序設(shè)計(jì)這兩個(gè)方面,
9、Threatstocomputingsystemsarecircumstancesthathavethepotentialtocauselossorharm;humanattacks
areexamplesofthreats,asarenaturaldisasters,inadvertenthumanerrors,andinternalhardwareorsoftware
flaws.
答案:對(duì)計(jì)算機(jī)系統(tǒng)的威脅是引起安全喪失或傷害的環(huán)境;人們的攻擊是威脅的例子,此外還有自然災(zāi)害、
人們無意識(shí)的錯(cuò)誤和內(nèi)部硬件或軟件缺陷等。

意妁)destructionofahardwaredevice,erasureofaprogramordatafile,orfailureofanoperatingsystemfile
managersothatitcannotfindaparticulardiskfile.
答案:在中斷情況上系統(tǒng)資源開始丟失,不可用或不能用。例如,蓄意破壞硬件設(shè)備,抹除程序或數(shù)據(jù)
文件,或造成操作系統(tǒng)的文件管理程序故障,以致不能找到某一磁盤文件。
四、漢譯英(本大題共10小題)
1、在ENIAC的研制中,一個(gè)天才的數(shù)學(xué)家VonNeuman(馮.諾伊曼)加入到Eckert和Mauchly團(tuán)隊(duì),他
們一起提出了儲(chǔ)存程序計(jì)算機(jī)的主意。這部機(jī)器被稱做電子離散變量自動(dòng)計(jì)算機(jī),或簡(jiǎn)稱EDVAC,是第一
部其設(shè)計(jì)包括了計(jì)算機(jī)所有特征的機(jī)器。
答案:WhileworkingontheENIAC,EckertandMauchlywerejoinedbyabrilliantmathematician,Johnvon
Neuman.Together,theydevelopedtheideaofastoredprogramcomputer.Thismachine,called(heElectronic
DiscreteVariableAutomaticComputer,orEDVAC,wasthefirstmachinewhosedesignincludedall(he
characteristicsofacomputer.
2、第一代計(jì)算機(jī)的特色是使用真空管為其主要電子器件。真空管體積大且發(fā)熱嚴(yán)重,因此第一代計(jì)算機(jī)體
積,蘢大,并且需要大量的空調(diào)設(shè)備保持冷卻。此外,因?yàn)檎婵展苓\(yùn)行不是很快,這些計(jì)算機(jī)運(yùn)行速度相對(duì)
較慢。
答案:First-generationcomputerswerecharacterizedbytheuseofvacuumtubesastheirprincipalelectronic
component.Vacuumtubesarebulkyandproducealotofheat,sofirst-generalioncomputerswerelargeand
requiredextensiveairconditioningtokeepthemcool.Inaddition,becausevacuumtubesdonotoperateveryfast,
thesecomputerswererelativelyslow.
3、在第二代計(jì)算機(jī)中,晶體管取代了真空管。雖然發(fā)明于1948年,但第一臺(tái)全晶體管計(jì)算機(jī)宜到1959年
才成為現(xiàn)實(shí)(投入使用)。晶體管比真空管體積小、價(jià)格低,而且運(yùn)行快而發(fā)熱少。
答案:Inthesecondgenerationofcomputers,transistorsreplacedvacuumtubes.Althoughinventedin1948,the
firstall-transistorcomputerdidnotbecomeavailableuntil1959.Transistorsarcsmallerandlessexpensivethan
vacuumtubes,andtheyoperatefasterandproducelessheat.
4、CuteFTP是一種基于Windows的文件傳輸辦議客戶程序,它允許用戶利用FTP的功能而不必了解協(xié)議的
詳細(xì)內(nèi)容。CuteFTP提供了用戶友好的Windows界面,而不是麻煩的命令行實(shí)用工具,從而簡(jiǎn)化了FTP的
使用。CuteFTP給PC初學(xué)者提供了上傳、下載和編輯世界各地近程服務(wù)器上文件的能力。
答案:CuteFTPisaWindowsbasedFileTransferProtocol(FTP)clientthatallowsuserstoutilizethecapabilities

5、面向?qū)ο蟮臄?shù)據(jù)庫可以存儲(chǔ)并處理更加復(fù)雜的數(shù)據(jù)結(jié)構(gòu),這種數(shù)據(jù)結(jié)構(gòu)稱為“對(duì)象",對(duì)象”可以
按層次組成“類”,低層的“類”可以繼承上層“類”的屬性:這是一種最靈活,最具適應(yīng)性的數(shù)據(jù)結(jié)構(gòu)。
答案:Object-orienteddatabasesstoreandmanipulatemorecomplexdatastructures,called“object”,whicharc
organizedintohierarchicalclassesthatmayinheritpropertiesfromclasseshigherinthechain;thisdatabase
structureisthemostflexibleandadaptable.
6、到目前為止,萬維網(wǎng)是因特網(wǎng)最受歡迎的部分。一旦花費(fèi)時(shí)間在Web上,你就會(huì)感覺到你能發(fā)掘無窮
無盡的內(nèi)容。Web允許以豐富、多樣的方式進(jìn)行通信,可以顯示文本、圖片、動(dòng)畫、照片、聲音和視頻。
答案:TheWorldWideWebisthemostpopularpartoftheInternetbyfar.OnceyouspendtimeontheWeb,you
willbegintofeellikethereisnolimittowhatyoucandiscover.TheWeballowsrichanddiversecommunication
bydisplayingtext,graphics,animation,photos,soundandvideo.
7、電子商務(wù)是最新的信息技術(shù)的大舞臺(tái),它使商務(wù)過程改進(jìn)和培訓(xùn)能聚集起真正的潛能,從而產(chǎn)生既可
重復(fù)又具突破性的結(jié)果。尤其在中國(guó),各類公司對(duì)該領(lǐng)域的需求十分強(qiáng)烈。
答案:eBusinessisthearenawherethelatestinformationtechnologies,businessprocessimprovementandtraining

類可以繼承層次鏈中更高一級(jí)類的特性,這種數(shù)據(jù)庫結(jié)構(gòu)最靈活,最具適應(yīng)性。
答案:Object-orienteddatabasesstoreandmanipulatemorecomplexdatastructures,called"objects",whicharc

9、當(dāng)多個(gè)文件或記錄間的關(guān)系不能用鏈表達(dá)時(shí),使用關(guān)系型數(shù)據(jù)庫。一個(gè)簡(jiǎn)單的非結(jié)構(gòu)列表變成一個(gè)表
或一個(gè)“關(guān)系”。多個(gè)關(guān)系可通過數(shù)學(xué)關(guān)系提供所需的信息。
答案:Relationaldatabasesarcusedwhereassociationsamongfilesorrecordscannotbeexpressedbylinks;a
simpleflatlistbecomesonetable,or“rclatiorT,andmultiplerelationscanbemathematicallyassociatedtoyield
desiredinformation.
10.MIDI格式實(shí)際上是由樂相制造商制訂的標(biāo)準(zhǔn),MIDI實(shí)際并非數(shù)字化的聲音,而是描述要演奏的音符
信息的集合。
答案:TheMIDIformatisactuallyaspecificationinventedbymusicalinstrumentmanufacturers.Ratherthan
beingadigitizedformofthesound,theMIDIspecificationisactuallyasetofmessagesthatdescribeswhat
musicalnoteisbeingplayed.

答案;新處理器開始IT技術(shù)的新時(shí)代
上周,英特爾公司向俄羅斯和其它獨(dú)聯(lián)體國(guó)家的公眾推出了英特爾XeonE5-2600系列處理器,它們更加
強(qiáng)大可靠,尤其是在能量消耗方面更加經(jīng)濟(jì)實(shí)惠。它們的問世意味著IT技術(shù)領(lǐng)域開始了一個(gè)新時(shí)代,標(biāo)志著

這些處理器主要是為服務(wù)器、數(shù)字處理中心和超級(jí)計(jì)算機(jī)設(shè)計(jì)的。這種處理器的出現(xiàn)并非偶然。根據(jù)
英特爾公司俄羅斯和其他獨(dú)聯(lián)體地區(qū)負(fù)責(zé)人DmiiriKonash就此事發(fā)表的看法,IT技術(shù)市場(chǎng)的發(fā)展速度極快,
根據(jù)預(yù)測(cè),到2015年與英特網(wǎng)連接的設(shè)施將有150億,用戶超過30億。

答案:支持多種外接設(shè)備的總線系統(tǒng)
隨著外接設(shè)備數(shù)量的不斷增加,想用擴(kuò)展卡來應(yīng)付每一種外圍設(shè)備越來越不現(xiàn)實(shí)了,這就產(chǎn)生了設(shè)計(jì)專
門支持多種外接設(shè)備的總線系統(tǒng),通常的例子就是現(xiàn)代計(jì)算機(jī)上的SATA接口,這就允許很多硬盤驅(qū)動(dòng)器不
需要卡就可以同計(jì)算機(jī)連接起來,但是把這些高性能系統(tǒng)用于低端設(shè)備,如鼠標(biāo)等就很不合算,這就導(dǎo)致同
