三是住房租赁市场发展。排除的依据是使用showinterfacesfastEthernet0/1counterserrors查看接口上的错误。控制层面负责运行交换机的操作系统,STP、路由协议、维护路由表、执行ACL等,控制层面包括交换机的CPU和内存。目前关于折叠屏的讨论中,多数观点认为它在有限的体积与重量情况下,可扩张屏幕的使用面积。根据普华永道和英国本地数据公司11日联合发布的报告,英国高街店铺今年上半年净减少1234家,为2010年以来同期最高数值。业界描绘的技术前景相当美好,但5G需要采用更高的频段,建设更多的基站,才有可能颠覆掉现有的2G、3G、4G市场。2、个人来稿不限数量,每一份来稿都有机会参与评奖。今年1月25日,平度联合莱西率先成立青岛北部景区联盟,向两地市民发放旅游惠民卡,持卡7折游览21家景区。

关于交换机接口的错误统计消息,可以通过showinterfacex/ycounterserrors来得到如上图1所示,现在来理解每个错误统计器的意义:如图2所示的交换机架构,通常交换机的架构由两个层面组成:一个控制层面、一个转发层面。Ironically,thetariffsandsanctionsagainstChinesetechcompaniesarepushingthegrowthoftechnologicallyindependent,homegrowntechhardwarecompaniesinChina.Thekeyenablerforthegrowthofanewindustry,especiallyatechindustry,isacustomerwhoprovidesasteadysourceofdemandforitsproducts.Fromthe1950stothe1980s,theU.S.militaryandNASAweretheprimedemandsourcesthatallowedtheearlyproducersofintegratedcircuitstostayinbusiness.And,theU.S.DefenseAdvancedResearchProjectsAgency,DARPA,providedthekeyfundingthatmadethecreationoftheinternetpossible.Aslateas1980,thefederalgovernmentprocuredmorethanhalfofallaircraftandtelecomsequipment.Thissupportedthecompaniesplusallowedthedevelopmentofspin-offconsumergoods.WithoutthisdemandfromtheU.S.government,thecompanieswouldnothavebeenabletodotheexpensiveresearchormakethehugeupfrontinvestmentthatmadethemicrochipindustrypossible.Inmarketsformorematuretechnologies,it'sveryhardforanewcompanytogrowifitrequiresbigupfrontcapitalinvestmentandfacesalreadyestablishedcompetitors.Thenewcomerwouldhavetotakecustomersawayfromtheoldcompaniesbycompetingoncostorquality.Anewproducerofchips,forexample,wouldhavetoinvestinfabricationfacilitiescostingbillionsofdollarsbeforereceivinganyreturn.Then,itwouldhavetochargelessorbuildabetterproductthanlong-establishedfirms-averydifficultproposition.Famously,Chinaimportsmorechipsthanitdoespetroleum.In2017,thecountryimported$260billionworthofchipsand$162billionworthofcrudeoil.Morethan$200billionofthechippurchaseswereU.S.-madechips,accordingtoBloombergdata.EvenmorewereU.S.-designedchips,forwhichU.S.companiesreceivedroyalties.YoumightthinkthiswouldbetoutedasahugesuccessforU.S.exporters.But,thecurrentsanctionsandthreatsofsanctionsagainstHuawei,ZTEandothershavepermanentlysouredthemarketforU.S.chipsandothertechnologies.AccordingtotheChinaSemiconductorIndustryAssociation,lessthan20percentofChinesedomesticchipdemandin2017,upfrom9percentin2015,wasmetbyChinese-madechips.OnceHuaweideploysitsownnewHarmonyoperatingsystem,williteverbewillingtorelyonGoogle'sAndroidagain?WillChinesetechcompaniesbewillingtorelyonU.S.chips?Forthatmatter,willcountriesaroundtheworldbewillingtobedependentonU.S.technology?Thedecisionsbeingmadenowareirreversible.BothChinesecompaniesandtheChinesegovernmenthaveinvestedheavilyincoreresearchandinthedevelopmentofnewtechproducts.But,realizingthegoalofcreatingamorevibrantandinnovativedomestictechindustrywouldbeverydifficultifthenewcompaniesandproductsfacedconstantcompetitionfromestablishedforeignplayers.Effectively,theU.S.tariffsandsanctionsarecreatingawindowofopportunityallowingChina'sinfanttechindustriestodevelopbyguaranteeingaprotectedmarket.IfChinaweretotrytolimittheimportsofU.S.technologyonitsown,youcanbesurethattheU.S.wouldfileacomplaintwiththeWorldTradeOrganization.Theimmediateshockofthesanctionsandtariffswillnodoubtcauseshort-term,evenmedium-term,disruptions.Forexample,RenZhengfei,Huawei'sCEO,acknowledgedthatthecompanywilllikelylose$30billionoverthenextseveralyearsasaresultofU.S.actions.ChinahasbeenbuildingitstechcapabilitiesformorethanadecadeandhasinvestedheavilyinRDaimedatbuildingchip-makingskills.Universitieshavecreateddepartmentstodevelopthetalentneeded.But,chip-makingisaveryhighlyspecialized,high-investmentbusinessandthereareonlyafewcapablecompaniesintheworld.VeluSinha,BainCompanypartnerinShanghai,wasquotedintheFinancialTimesinJanuaryconcludingthatChinesesemiconductorscienceandchipdesigncapabilitiesareatthecuttingedge,buttheindustryneedsaccesstothemostadvancednext-generationtoolsforchipmaking."Itisnotaquestionofif,itisaquestionofwhen.Butwearenottalkingayearortwo,we'retalkingfiveto10yearsbeforethosetechnologiesinChinagetcaughtup,"SinhatoldFT.TheU.S.sanctionsandtariffsarelikelytopushupthisschedulesinceChinesechip-makersknowthattheyhaveaverylargeandveryeagercustomerbase.Thisreducestheriskinthehugeinvestmentneededtobuildnext-generationfoundries.TheU.S.andChinesetechmanufacturingandsupplyprocessesaresointertwinedthatnoonereallyknowswhatwillhappeniftheyareforcedtoseparate.SomecompanieswilllikelymovesomemanufacturingoutofChinatoVietnamorIndiatoavoidtariffs.But,thesewillbelowvalue-added,labor-intensivemanufacturingprocessesthatarenotdependentonChina'sunequalledinfrastructureormanufacturingclusters.Manyotherswillhavetojustpaythetariffs.Inanycase,priceschargedtoconsumerswillhavetorise.Inthelongerterm,techcompetitionamongmultipletechcenterswillbegoodfortheworld.Overthepastdecade,firmsinSiliconValleyhaveusedtheirmonopolisticpowertostampoutcompetitionaroundtheworld,withthesoleexceptionofChina.ItisunreasonablefortheU.S.totrytoprotectmonopolistictechgiantsfromworldcompetition.Mostcountrieshaveanindustrialpolicy,whethertheycallitthatornot.TheGermangovernment's"Industry4.0"intendstousegovernmentpolicytofacilitatetheupgradingofindustrytousethecomingartificialintelligenceadvancesinandroboticstechnologies.AirbuswouldnothavebeencreatedwithoutsubstantialsubsidiesfromEuropean
