1.Pair work:What doyou knowaboutthe Internet Try tofindas muchinformation asyou can,and reportyourinformation to your partner.For referenceThe Internet is a giantnetwork of computers locatedall overthe worldthat communicatewith each other.The Internetis aninternational collectionofcomputernetworks thatall understand a standardsystemof addressesand commands,connected togetherthrough backbonesystems.It wasstarted in1969,when theU.S.Department ofDefence establisheda nationwide network toconnect a handful ofuniversities andcontractors.The originalidea wasto increasecomputing capacitythat couldbe sharedby usersin manylocationsand tofind outwhat itwould takefor computernetworks tosurvive anuclear waror otherdisasterby providingmultiple pathsbetween users.People onthe ARPNETas thisnationwidenetworkwasoriginally calledquickly discoveredthat theycould exchange messages andconduct electronicconferenceswith distantcolleagues forpurposes thathad nothingto dowiththemilitary industrialcomplex.If somebody else hadsomething interestingstored ontheir computer,it wasa simplematter toobtaina copyassuming theowner didnot protectit.Over theyears,additional networksjoined whichadded accessto more and morecomputers.The firstinternationalconnections,to Norwayand England,were addedin
1973.Today thousandsof networksandmillions ofcomputers areconnected tothe Internet.It isgrowing soquickly thatnobody can say exactlyhowmany users“On the Net”.TheInternetisthelargest repositoryof informationwhich can provide verylarge networkresources.The networkresources canbe dividedinto networkfacilities resourcesand networkinformation resources.The networkfacilities resources provide usthe abilityof remotecomputation andcommunication.Thenetwork informationresourcesprovideus allkinds ofinformationservices,such asscience,education,business,history,law,art,and entertainment,etc.The goalof your use ofthe Internetis exchangingmessages orobtaining information.What youneed toknowis that you canexchangemessagewith othercomputers onthe Internet and useyour computeras aremote terminal ondistant computers.But theinternal detailsofthelink areless important,as longas itworks.If youconnect computerstogether ona network,each computermust havea uniqueaddress,whichcould beeither aword ora number.For example,the addressof Samscomputer couldbe Sam,oranumber.TheInternetisahuge interconnectedsystem,but ituses justahandfulof methodto move data around.Until therecent explosionof publicinterest intheInternet,the vastmajority ofthe computersonthe Net usetheUnix operatingsystem.As aresult,the standardUnix commandsfor certainInternet serviceshaveentered theonline communityslanguages asboth nounsand verbsto describethe servicesthemselves.Someof theservices that theInternetcanprovideare:Mail,Remote use of anothercomputer Telnet,FileTransfer FTP,News,and Liveconversation.The most commonly usednetwork serviceis electronicmail E-mail,or simplyas mail.Mail permitsnetworkusers tosend textualmessages toeach other.Computers andnetworks handledelivering themail,sothat communicatingmail usersdo not have tohandle detailsof delivery,and donothaveto bepresent atthesame timeor place.The simplestway toaccess afile onanother hostis tocopy itacross thenetwork toyour localhost.FTPcan dothis.Presently,a userwith anaccount onany Internetmachine canestablish alive connectionto anyothermachine ontheNetfrom theterminal inhis ownoffice orlaboratory.It isonly necessaryto usethe Unixcommandthat setsup aremoteterminalconnection Telnet,followed bythe addressofthedistant machine.Before youcan usetheInternet,you mustchoose away tomovedatabetween theInternetandyour PC.This linkmay bea high-speed datacommunication circuit,a localarea networkLAN,a telephonelive oraradio channel.Most likely,you willuseaModem attachedtoyourtelephone lineto talktotheInternet.Naturally,the qualityof yourInternet connectionand service,like manyother thingsin life,is dictatedbythe amountof moneythatyouare willingto spend.Although allthese servicescan wellsatisfy theneeds ofthe usersfor informationexchange,a definiterequirementis neededfor the users.Not onlyshould theusers knowwhere theresources locates,but alsoheshould knowsome operatingcommands concernedto easethe searchingburden oftheusers,recently someconvenientsearching toolsappears,such asGopher,WWW andNetscape.World wideweb wwwisanetworked hypertextprotocol anduser interface.It providesaccess tomultipleservices anddocuments likeGopher doesbut ismore ambitiousin itsmethod.A jumpto otherInternetservice canbe triggeredby a mouse clickonanhotlinkedn word,image,or iconontheWeb page.As moreand moresystems jointheInternet,and asmoreandmore formsof informationcan beconvertedto digitalform,the amountof stuffavailable toInternet userscontinues to grow.At somepointsveiy soonafter thenationwide andlater worldwideInternet startedtogrow,people beganto treattheNetasa community,with itsown traditionand customs.For example,somebody wouldask aquestion inaconference,andacomplete strangerwould sendback ananswer:after thesame questionwere repeatedseveraltime bypeoplewhohadnt seenthe originalanswers,somebodyelsegathered listof nfrequentlyaskedquestions0and placedit wherenewcomerscould findit.So wecansaythattheInternetisyour PCswindow tothe restoftheworld.
