Withsuchexpandedaccesstoinformation,however,theconsumersandthebusinesspersonofthefuture mustdevelopkeenskillsofanalysis,organization,andverbalizationtosortthroughtheresourcesbeingmade available. BirthoftheInternet TheInternetcameintoexistenceatthetimeoftheColdWar.Theoriginalnetworkedsitesaremilitarybases andcamps,universities,andfirmswhohavebusinessconcernswiththedefensedepartment.In1964,the UnitedStatescomputerscientistsbeganresearchingoncomputernetworkingtodecreasethevulnerabilityof thesystemsfromanybombattack.Themainobjectiveoftheprojectwastobuildanetworkthatwould protecttheflowofinformationfromonesitetoanotherthroughredundantcommunicationlines.Thereason fortheredundancyofrouteswastokeepthetransitionofinformationuninterruptedincaseoftheoccurrence ofwar. ThisresearchwasfundedbytheAdvancedResearchProjectsAgency(ARPA),whichgavethe Internetitsfirstname,theARPAnet. ARPAnetwasoriginallymadeupoffourcomputerseachlocatedattheUniversityofCaliforniaatLos Angeles,StanfordResearchInstitute,UniversityofCaliforniaatSantaBarbara,andtheUniversityofUtah. Thesefourcomputersservedasanetwork’shostnodes.Ahostnodeorahostisanycomputerthatdirectly connectstothenetwork(Shelly/Cashman/Vermaat).Whatahostdoesisittransfersandstoresdataand messagesonhigh-speedcommunicationlinesandprovidesnetworkconnectionsforothercomputers. In1984theARPAnetsplitintotwointerconnectednetworks.TheMILNETwascreatedformilitaryuse,and theARPAnetwasretainedforcivilianuseorforeducationalpurposes. TheNationalScienceFoundation(NSF)andotheragenciesoftheU.S.governmenthavecontrolledaccessof theInternetsincethemid-1980s.Thus,nootherpersonorcompanyasidefromthegovernmentcanusethe Internet.InApril1995,thecontrollershipoftheInternetwashandedovertoindependentgoverningbodies whicheaseoffentryforalmosteveryoneinterestedintheInternet.Therapidriseofpersonalcomputersand localareanetworksisresponsibleforwhattheInternethasbecomeasoftoday. InternetResources ItistimetoknowhowtheInternetworksafterwehavelearnedhowitbegan.Asdiscussedearlier,Internetis anetworkofinterconnectedofcommunicationslinesthatcreatesomesortofahighwaysystemfor transportingdata(ParsonsandOja).Thus,themainchannelsoftheInternetarecalledtheInternetbackbone wherethebulkofInternettrafficisfedthereviaNetworkAccessPoints(NAPs).Thesemainrouteswere constructedandmaintainedbymajortelecommunicationscompaniesworldwide,suchasSprintinwhich canmovehugeamountsofdataatunimaginablespeeds. Inaddition,theInternetalsoincludescomplexcollectionofregionalandlocalcommunicationlinks.These linkscompriseoflocaltelephonesystems,cabletelevisionlines,cellulartelephonesystems,andpersonal satellitedishes(ParsonsandOja). TheInternet’scommunicationsystemenablesthedatatobetransportedtoandfrommillionsofcomputers andelectronicdevicestoanypartoftheglobe.Thedatatransportediscompatibletoallkindsofplatforms- fromPCstoMacs,andevenbetweenpersonalcomputersandmainframes.Thus,datatransmittedbetween LaboratoryExercise12–InternetExplorerFundamentals

InternetConnections AcommunicationlinkmustbeestablishedbetweenacomputerandtheInternetto fullybenefitfromwhattheInternethastooffer.Therearealotofwaystoconnectto theInternet,suchasdial-upconnections,ADSLconnections,andcableconnections.
