Early electronic computers, like the ENIAC, used a device called the vacuum tube.

早期的电子计算机， 如 ENIAC，使用一种称为空管的装置。

ENIAC could perform 5000 ten-digit additions or subtractions per second, many, many times faster than any machine that came before it.

ENIAC 执行 5000 次位数加减法，比它的前辈快很多很多倍。

In 1949 the electronic computer ENIAC was used for 70 machine hours to calculate pi to more than 2,000 decimal places.

1949 年，电子计算机 ENIAC 花 70 机器工时算出了π小数点后 2000 多位。

With 18,000 triodes, ENIAC was nearly the size of a tennis court and weighed 30 tons.

ENIAC 拥有 18, 000 个三极管， 几乎有一个网球场那么大，重达 30 吨。

ENIAC's functionality can now be surpassed by a single fingernail-sized microchip containing billions of transistors.

ENIAC 的功能现在以被包含数亿个晶体管的单个指甲盖大小的微芯片所超越。

Even the first electronic computers, like Colossus and ENIAC, were configured using huge panels of mechanical controls and patch wires.

即使是第一台电子计算机，如 Colossus 和 ENIAC，也是使用巨大的机械控制面板和接线来配置的。

They enabled huge ambitious computing projects to be undertaken, like ENIAC, EDVAC, Atlas and Whirlwind, all mentioned in previous episodes.

它们使雄心勃勃的大型计算项目得以实施，如 ENIAC、EDVAC、Atlas 和 Whirlwind，所有这些都在前几集中提到。

After the war, Turing and John von Neumann designed the first true programmable electronic computer, ENIAC, based on Turing's designs.

战后，图灵和约翰·冯·诺依曼根据图灵的设计设计出了第一台正意义上的编程电子计算机 ENIAC。

Enter the The Electronic Numerical Integrator and Calculator – or ENIAC – completed a few years later in 1946 at the University of Pennsylvania.

电子数值积分计算机 " ENIAC" 在 1946 年在宾夕法尼亚大学完成建造。

An early and practical approach was developed by J. Presper Eckert, as he was finishing work on ENIAC in 1944.

J. Presper Eckert 在 1944 年完成 ENIAC 的工作时开发了一种早期实用的方法。

But with that many vacuum tubes failures were common, and ENIAC was generally only operational for about half a day at a time before breaking down.

但由于空管故障非常常见，ENIAC 次故障前一般只能运行半天左右。

Woz spent a lot of time at home reading his father's electronics journals, and he became enthralled by stories about new computers, such as the powerful ENIAC.

沃兹花了大量的时间在家阅读父亲的电子学期刊，他着迷于关于新式计算机的那些故事，比如强大的埃尼阿克（ENIAC)。

For example, the ENIAC, consisted of more than 17,000 vacuum tubes, 70,000 resistors, 10,000 capacitors, and 7,000 diodes, all of which required 5 million hand-soldered connections.

例如，ENIAC 由 17,000 多个空管、70,000 个电阻器、10,000 个电容器和 7,000 个二极管组成，所有这些都需要 500 万个手工焊接连接。

After working on ENIAC, Eckert and his colleague John Mauchly, set out to build a bigger and better computer called EDVAC, incorporating Delay Line Memory.

在 ENIAC 上工作之后，Eckert 和他的同事 John Mauchly 着手建造一台更大更好的计算机，称为 EDVAC，其中包含延迟线存储器。

But there was a problem… In the era of one-off computers, like the Harvard Mark 1 or ENIAC, programmers only had to write code for that one single machine.

但是有一个问题… … 在一次性计算机时代，比如 Harvard Mark 1 或 ENIAC，程序员只需为那一台机器编写代码。
