This is the ENIAC, one of the first computers ever invented.

这就是 ENIAC，最早发明计算机之一。

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

早期子计算机， 如 ENIAC，使一种称为真空管装置。

The ENIAC was the first programmable general-purpose electronic digital computer to  be produced.

ENIAC 是第一台生产可编程子数字计算机。

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

ENIAC 每秒可执行 5000 次十位数加减法，比它前辈快很多很多倍。

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

1949 年，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 三极管， 几乎有一网球场那么大，重达 30 吨。

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过。

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·诺依曼根据图灵设计设计出了第一台真正意可编程子计算机 ENIAC。

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 工作时开发了一种早期实方法。

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

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

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

即使是第一台子计算机，如 Colossus 和 ENIAC，也是使巨大机械控制面板和接线来配置。

And they weren't all that fun either, computers like ENIAC were actually just giant calculators that help people solve really complicated math problems.

而且它们也不是那么有趣，像 ENIAC 这样计算机实际只是巨大计算器， 可以帮助人们解决非常复杂数学问题。

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.

但由于真空管故障非常常见，ENIAC 每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.

沃兹花了大量时间在家阅读父亲子学期刊，他着迷于关于新式计算机那些故事，比如强大埃尼阿克（ENIAC)。

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 工作之后，Eckert 和他同事 John Mauchly 着手建造一台更大更好计算机，称为 EDVAC，其中包含延迟线存储器。

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 多真空管、70,000 阻器、10,000 容器和 7,000 二极管组成，所有这些都需要 500 万手工焊接连接。

In the 1970s,   the patent for the ENIAC technology entered the public domain, and it was able to be modified,   becoming the blueprint for modern computers.

20世纪70年代，ENIAC技术专利进入公共领域，并且可以进行修改，成为现代计算机蓝图。

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。

Although the ENIAC was developed to aid in WWII, it wasn't completed until 1946, when the war  ended, and it was first used in calculations for the construction of a hydrogen bomb.

尽管 ENIAC 是为了二战而开发，但直到 1946 年战争结束后才完成，并首次于制造氢弹计算。
