Comma-free code. A comma-free code is block code in which no concatenation of two code words contains a valid code word that overlaps both. [1] Comma-free codes are also known as self-synchronizing block codes [2] because no synchronization is required to find the beginning of a code word.
Japanese counter word. In Japanese, counter words or counters ( 助数詞, josūshi) are measure words used with numbers to count things, actions, and events. Counters are added directly after numbers. [1] There are numerous counters, and different counters are used depending on the kind or shape of nouns that are being described.
This template counts the number of words that goes into its first parameter. It serves as a basic word count function in areas where word count is important (such as Arbitration Committee meetings, etc.)

The prefix code {00, 11} is not self-synchronizing; while 0, 1, 01 and 10 are not codes, 00 and 11 are. The prefix code {ab,ba} is not self-synchronizing because abab contains ba. The prefix code b ∗ a (using the Kleene star) is not self-synchronizing (even though any new code word simply starts after a) because code word ba contains code word a.
A linear code of length n and dimension k is a linear subspace C with dimension k of the vector space where is the finite field with q elements. Such a code is called a q -ary code. If q = 2 or q = 3, the code is described as a binary code, or a ternary code respectively. The vectors in C are called codewords.
As stated above, Berger codes detect any number of unidirectional errors. For a given code word, if the only errors that have occurred are that some (or all) bits with value 1 have changed to value 0, then this transformation will be detected by the Berger code implementation. To understand why, consider that there are three such cases: Some 1s ...
