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.
现代计算机确切的发明时间,我们已无可考究。大概在19世纪30年代开始,并跨越整个40年代,一系列类似计算机的机器逐渐问世。但这些机器并不具有当今计算机的所有特征。它们的特征可阐述如下:由电子器件构造,具备程序存储能力,并有一定功能用途。
