The first electronic computer: 1946 was successfully developed at the University of Pennsylvania in February, 1986. Meanwhile, Feng. NEUMANM developed the universal electronic computer EDVAC, which is considered as the prototype of modern computer. Wilkins developed EDSAC in 1949. Turing developed ACE in 1950. Success. Name it ENIAC. According to the physical devices used by computers, the development of computers is generally divided into the following four eras. 1 the first generation (1946-1958) electron tube computer era. The second generation (1958— 1964) transistor computer era. The third generation (1965 ——1970) integrated circuit computer era. The fourth generation (1970-~) LSI computer era.
