One of the largest electro-mechanical computers built was the Harvard Mark I, completed in 1944 by IBM for the Allies during World War 2.

最大的电子计算机之一叫做哈佛马克 1 号 (Harvard Mark I)， 于1944在第二次世界大战中由 IBM 为同盟国而建造。

But before we get into all that, we should start at computing's origins, because although electronic computers are relatively new, the need for computation is not.

但在我们了解这一切之前，我们计算的起源讲起虽然电子计算机是比较新出现的，但人类对于计算的需要并不是。

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

早期的电子计算机，如ENIAC，使用了一种名为真空管的设备。

So in summary, electronic computers were invented to help solve complicated math problems.

所以总结一下，电子计算机被发明出来是为了帮助解决复杂的数学问题。

Fortuitously, one of the first electronic computers with a stored memory programme had just been built in the Cambridge Mathematics Lab.

巧合的是，剑桥大学数学实验室刚刚建成了一台具有存储程序功能的早期电子计算机。

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真正意义上的可编程电子计算机 ENIAC。

The world's first General-Purpose electronic computer, the Eniac, completed in 1946, used a ton of them.

世界上第一台通用电子计算机埃尼阿克，在1946完成，使用了大量的它们。

In 1953, there were only around 100 computers on the entire planet and at this point, the USSR was only a few years behind the West in computing technology, completing their first programmable electronic computer in 1950.

1953，全球只有大约100台计算机，而此时苏联在计算技术上仅比西方落后几，在1950就完成了他们的第一台可编程电子计算机。

After hundreds of years of trying, inventors finally came up with these, some of the very first electronic computers.

经过数百的尝试， 发明家终于发明了这些，一些最早的电子计算机。

Electronic computers work the same way, but instead of physical arrangements, the numbers are represented by electric voltages.

电子计算机的工作原理与此相同，只不过数字的表示方式不是物理排列，而是通过电压来体现。

Some early electronic computers were ternary, that's three states, and even quinary, using 5 states.

一些早期的电子计算机是三进制的，也就是三种状态，甚至还有五进制的，使用五种状态。

Now electronic computer memory is great and all, but you still have to load the programming data in to the computer before it can run.

现在电子计算机内存很棒，但你仍然需要先把编程数据加载到计算机中，它才能运行。

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

即使是最早的电子计算机，如科洛萨斯和埃尼阿克，也是通过巨大的机械控制面板和补丁线来配置的。

Named after John von Neumann, a prominent mathematician and physicist, who worked on the Manhattan project and several early electronic computers.

以着名数学家和物理学家冯·诺依曼的名字命名，他曾参与过曼哈顿计划和几台早期电子计算机的研发。
