19、存儲(chǔ)和程序”原理，是他在1946年提出的。按照馮諾依曼原理研制的世界上第一臺(tái)二進(jìn)制數(shù)現(xiàn)代電子數(shù)字計(jì)算機(jī)EDSAC于1949年制成。目前主要的計(jì)算機(jī)類型都是馮諾依曼計(jì)算機(jī)。Word Practice Exercise I Exercise II Exercise IIIExercise IWord PracticeFill in the blanks according to the pictures.m_nit_ _m_ _seo uo o rWord Practicekey_ _ _ _ _secre_ _ _ _ t a r yb o a r dWord Practice ty_ _ wr
