It is hard to say exactly when the puter was invented. Starting in the 1930s and through the 1940s, a number of machines were developed that were puters. But most of these machines did not have all the characteristics that we associate puters 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。

The Invention of puter
One of the puterlike devices was developed in Germany by Konrad Zuse in 1941. Called the Z3, it was general-purpose, stored-program machine with many electronic parts, but it had a mechanical memory. Another puting 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 puter, 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,但是它的存储器是机械的。。它被称为自动序列控制计算器Mark I,或简称哈佛Mark I。然而,这些机器都不是真正的
