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意义上编程电子计算机 ENIAC。

This allowed early computers like the ENIAC to perform calculations using thousands of vacuum tube switches to represent binary digits.

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.

早在1944年，J. 帕斯珀·埃克特在完成ENIAC工作时，就开发了一种早期且实用方法。

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 每次故障前一般只能运行半天左右。

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

而且它们也不怎么有趣，像ENIAC计算机这样机器实际上只是巨大计算器， 帮助人们解决非常复杂数学问题。

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电子学期刊，他着迷于关于新式计算机那些故事，比如强大埃尼阿克（ENIAC)。

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由超过17000根空管、70000个电阻器、10000个电容器和7000个二极管组成，所有这些都需要进行5百万个手工焊接连接。

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项目之后，埃克特和他同事约翰·莫奇利着手建造一更大更好计算机EDVAC，这计算机采用了延迟线存储器。

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.

但是有一个问题… … 在一次性计算机时代，比如哈佛马克1号或埃尼阿克，程序员只需要为那一特定机器编写代码。

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，并首次用于制造氢弹计算。
