不幸的是,Babbage从来没有装配过他的计算机,并且直到20世纪,有了电子管的发明,一台可实行的电子计算机的组装变得可行.
电子管是一种可以阻拦,放大或者作为电流的开关的设备.在20世纪20年代和20世纪30年代期间,科学家们研究了如何将这些列阵连接起来,接受代表数字的电子信号,根据节目处理信号,并且输出结果.然而电子管计算机非常巨大,编程时也需要通过塞住和拔去电缆更换他们的电路.

Unfortunately.Babbage never assembled his computer.and it was not until the 1900S,with the invention of the electron tube,that components for a viable electronic computer became available.
An electron tube is a device that can block,amplify,or act as an on/off switch for an electric current.During the 1920S and 1930s,
scientists investigated how to link these devices in arrays that would accept electric signals representing numbers,process the signals according to programme,and output the results.whereas electron-tube computers were huge,and programming them involved changing their circuitry by plugging and unplugging cables.
