古代西方人用莎草纸作为书写材料，将多张莎草纸粘贴到一起做成卷轴，相当于一本书。卷轴中的第一页在古希腊语中被称为protokollon，由proto（第一）+kollon（粘贴），字面意思就是“卷轴中的第一页”。这就是protocol的词源。由于卷轴的第一页通常用来展现整本书的目录和勘误表，因此protocol引申为“初稿、草案”。后来，该词主要应用于外交领域，被用来表示“外交会议记录、外交协议草案、外交协议”，继而表示“外交活动的礼仪”。现在，该词已经不再局限于外交领域，可以表示各种礼仪、礼节程序。在通信领域，表示“通信协议”，其实也就是通信双方的“礼节程序”。

小知识
Protocol is most often used when talking about the rules of government or official agencies. It is derived from the French and refers to the correct rules of etiquette for diplomats.
The term protocol is used in many areas besides diplomatic ones. School marching bands or college admissions offices follow protocols, and doctors use them to treat patients with specific conditions. In tech circles, a protocol is a set of standards that programmers follow so that their work can be decoded by other computers. The p in the http of a web address is short for protocol. Without this type of protocol, you would not be able to read this page.
