似乎大多数现代(如过去 20 年)处理器都使用了小端，或者至少更喜欢它(如果是双端)。他们将 big-endian 设为所有网络协议(protocol)的通用顺序是否有原因？除了更容易用于大端处理器之外，它有什么实际优势吗？

Answer 1

选择大端可能是因为那个时代的大多数计算机(什么，1960 年代后期？)都使用它。

这么多年后，他们怎么能预测 80x86 系列的流行及其对小端序的使用？

根据Wikipedia :

An often-cited argument in favor of big-endian is that it is consistent with the ordering commonly used in natural languages.[9] Spoken languages have a wide variety of organizations of numbers: the decimal number 92 is/was spoken in English as ninety-two, in German and Dutch as two and ninety and in French as four-twenty-twelve with a similar system in Danish (two-and-four-and-a-half-times-twenty). However, numbers are written almost universally in the Hindu-Arabic numeral system, in which the most significant digits are written first in languages written left-to-right, and last in languages written right-to-left.
