Chapter 1 The History and Future of Computers 1. 1 The Invention of the Computer It is hard to say exactly when the modern computer was invented. Starting in the 1930s and through the 1940s, a number of machines were developed that were like computers But most of these machines did not have all the characteristics that we associate with computers today. These characteristics are that the machine is electronic, that it has a stored program, and that it is general purpose. 很难确切地说现代计算机是什么时候发明的。从20世纪30年代到40年 代,制造了许多类似计算机的机器。但是这些机器大部分没有今天我们所 说的计算机的所有特征。这些特性是:机器是电子的,具有储存的程序而 且是通用的。 《什第机专出美语

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 -6

Chapter 1 The History and Future of Computers 1. 1 The Invention of the Computer 1.1.1 The ENiac Perhaps the most influential of the early computerlike devices was the Electronic Numerical Integrator and Computer, or ENIAC. It was developed by J. Presper Eckert and John Mauchly at the University of Pennsylvania. The project began in 1943 and was completed in 1946. The machine was huge; it weighed 30 tons and contained over 18,000 vacuum tubes 也许早期最具影响力的类似计算机的装置应该是电子数字积分计算机 或简称 ENIAC。它是由宾夕凡尼亚大学的. Presper Eckert和John Mauchly研制的。该工程于1943年开始,并于1946年完成。这台机 器极其庞大,重达30吨,而且包含18000多个真空管。 《什第机专出美语

Chapter 1 The History and Future of Computers 1. 1 The Invention of the Computer 1.1.1 The ENiac The ENiaC was a major advancement for its time. It was the first general-purpose, electronic computing machine and was capable of performing thousands of operations per second. It was controlled, however, by switches and plugs that had to be manually set. Thus, although it was a general-purpose electronic device, it did not have a stored program. Therefore, it did not have all the characteristics of a computer ENIAC是当时重要的成就。它是第一台通用型电子计算机器,并能够执 行每秒数干次运算。然而,它是由开关和继电器控制的,必须手工设定。 因此,虽然它是一个通用型电子装置,但是它没有储存程序。因此它 不具备计算机的所有特征。 《什第机专出美语 -8

Chapter 1 The History and Future of Computers 1. 1 The Invention of the Computer 1.1.1 The Eniac While working on the ENIAC, Eckert and Mauchly were joined by a brilliant mathematician, John von Neuman. Together, they developed the idea of a stored program computer. This machine, called the electronic Discrete variable Automatic Computer, or EdVaC, was the first machine whose design included all the characteristics of a computer. It was not completed, however, until 1951 在 ENIAC的研制中,一个天才的数学家 Von Neuman(冯诺伊曼加入 到 Eckert和 Mauchly团队他们一起提出了储存程序计算机的主意。这部 机器被称做电子离散变量自动计算机,或简称 EDVAC,是第一部包括了计 算机所有特征的机器。然而,直到1951年,它一直没有完成。 《什第机专出美语 9

Chapter 1 The History and Future of Computers 1. 1 The Invention of the Computer 1.1.1 The eniac Before the edvac was finished. several other machines were built that incorporated elements of the EDVAC design of Eckert, Mauchly, and von Neuman. One was the Electronic Delay Storage Automatic Computer, or EDSAC, which was developed in Cambridge, England. It first operated in May of 1949 and is probably the world's first electronic stored-program, general-purpose computer to become operational. The first computer to operate in the United States was the Binary Automatic Computer, or BINAC, which became operationalin August of 1949 在EDVC完成之前,其他一些机器建成了,它们吸收了 Eckert MauM和 Neuman设计的要素。其中一部是在英国剑桥研制的电子延迟 存储自动计算机或简称 EDSAC,它在1949年5月首次运行,它可能是世 界的第一台电子储存程序、通用型计算机投入运行。在美国运行的第 部计算机是二进制自动计算机,或简称BNAC它在1949年8月投入运行。 1-10
