(AlanTuring)是一位英國(guó)數(shù)學(xué)家、邏輯學(xué)家，被譽(yù)為“計(jì)算機(jī)科學(xué)之父”和“人工智能之父”。他于1936年提出了“圖靈機(jī)”的概念。微芯片是一種高度集成的電子電路，是現(xiàn)代計(jì)算、通信、制造和交通系統(tǒng)的關(guān)鍵組成部分。量子計(jì)算機(jī)是一種利用量子力學(xué)原理工作的計(jì)算機(jī)。它使用量子比特來(lái)存儲(chǔ)信息。盡管量子計(jì)算機(jī)目前還處于發(fā)展階段，但它們有潛力在未來(lái)解決許多我們現(xiàn)在難以解決的問題。文化背景Readthepassageandanswerthequestions.1.Whowasfirstcomputerprogrammer?2.Whatisthebasisforallmoderncomputers?3.Werecomputersbigorsmallinthe1940s?4.WhodesignedthefirstPCforthegeneralpublic?AdaLovelace.Theywerebig(asthesizeofaroom).AUScompany.TheTuringmachine.Completethetablebasedonyourownunderstanding.AnswerReasonThefuturecomputersProblemwemayfaceNo.Humanbrainscanproducenewideasbutcomputerscannot.Theymaybetinyandquantumcomputerswillbethenextbigbreakthrough.Howtoadapttotherapiddevelopmentofcomputersandimproveourlife.Isthecomputerclevererthanhuman?Doyouagreethatcomputerswillbeabletodoallourjobsinthefuture?Givereasons.GroupA-prosGroupB-cons
