Chapter 1 The History and Future of Computers 1. 1 The Invention of the Computer One of the first computerlike devices was developed in Germany by Konrad Zuse in 1941. Called the Z, it was general-purpose, stored- program machine with many electronic parts, but it had a mechanical memory. Another electromechanical computing machine was developed by Howard Aiken, with financial assistance from IBM, at Harvard University in 1943. It was called the Automatic Sequence Control Calculator Mark I, or simply the Harvard Mark I. Neither of these machines was a true computer, however, because they were not entirely electronic 第一个类似计算机的装置之一是1941年由德国的 Konrad zuse研制 的,叫做z3,它是通用型储存程序机器,具有许多电子部件,但是它鯨存 储器是机械的。另一台机电式计算机器是由霍华德艾坎在IBM的资助下 于1943年在哈佛大学研制的。它被称为自动序列控制计算器 Mark li或 简称哈佛 Mark I。然而,这些机器都不是真正的计算机因为它们不是完 全电子化的。 《什第机专出美语 -6Chapter 1 The History and Future of Computers 计算机专业英语 1-6 1.1 The Invention of the Computer One of the first computerlike devices was developed in Germany by Konrad Zuse in 1941.
