Chapter 1 The History and Future of Computers
It is hard to say exactly when the modern computer was
invented. Starting in the 1930s and through the 1940s, a number
of machines were developed that were like computers. But most
of these machines did not have all the characteristics that we
associate with computers 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。
