Half a century has past since the first computer “ eniac “ had been made . in this period , computer science and technology make an influence far and wide on modern science and technology 從第一臺計算機馮?諾依曼機誕生至今的半個多世紀以來,計算機科學與技術對現代科技產生了深遠影響并已滲透到人類生活的方方面面。

The first commercial computer , eniac , incorporated 18 , 000 vacuum tubes , weighed 30 tons , filled several large rooms , and consumed enough power to light 10 homes 第一代的商業電腦? ?電子數字積分計算機,合并了18000個真空管,重達30噸,占地面積相當于幾間大房間,耗費的能量足夠供10個家庭照明。

Eniac ( for “ electronic numerical integrator and computer “ ) , the first general - purpose electronic computer , is unveiled at the university of pennsylvania 1946年的今天,首臺通用的電子計算機? ?艾尼亞克(意為“電子數字積分器與計算機” ) ,在賓夕法尼亞大學揭開了面紗。

Since the first electronic computer called eniac was built in 1946 , computers have gone through four generations 自從1946年被稱作eniac的第一臺計算機問世以來,計算機已經經歷了四個發展階段。

It takes two days to set up problems that eniac solves in two seconds 需要2天時間設計的問題, eniac僅用2秒鐘就能解決了。
