In the early days, when computers only performed one computation like calculating artillery range tables – the entire storage operated like one big file.

在早期，当计算机只执行一种计算，如计算火炮射程表时——整个存储就像一个大文件一样运行。

Range Tables were created that allowed gunners to look up environmental conditions and the distance they wanted to fire, and the table would tell them the angle to set the canon.

人们便制作了射程表来让炮手通过查询环境条件和他们希望炮弹飞过的距离 这张表便会告诉他们需要设置的角度。
