the most common sense of 码字 is to type, as in 码字不易,如果您觉得对你有所帮助,可以点赞、收藏、转发 or 我的国庆假期,五天时间写了九万七千多字。因为十月一号和明天要开一天车,所以只有五天码字。

and it seems to have a very technical meaning '(communication) code word'.

Looks like we got 码字 mixed up with 码子.


2) I see zdic defines 码字 as 计数的号码;代现金的筹码;尺码

Looks like zdic also got 码字 mixed up with 码子!

首先,对上层业务数据进行信道编码,生成一个或多个码字(Codeword)。

在编码理论中,循环码(英语:cyclic code)是一种分组码,每个码字循环移位会得到同样属于该码的另一个码字。

一个线性码的两个码字之间的最小距离等于任何非零码字的最小汉. 明重量。 例:码C={0000,1010,0101,1111}是一个分组长度为4的线性分组码。

前置碼(英語:Prefix code),又譯前綴碼、前綴編碼,是一種編碼系統。這種編碼系統通常是可變長度編碼,在其中的每個碼字,都具備「前置性質」(prefix property),也就是說,在編碼中的每個碼字,都不能被其他碼字當成前置部位。

"a prefix code is a code in which no codeword is a prefix of another codeword, ..."

"Introduction to information theory and coding : Optimal prefix codes - Huffman Algorithm. Note : illustrations in the binary case. Let n be the length of the longest codeword (q-ary code)."
