Code-switching is different from plurilingualism in that plurilingualism refers to the ability of an individual to use multiple languages, [1] while code-switching is the act of using multiple languages together. Multilinguals (speakers of more than one language) sometimes use elements of multiple languages when conversing with each other.
The word Arizona was not in the German codebook and had therefore to be split into phonetic syllables. Partially burnt pages from a World War II Soviet KGB two-part codebook. In cryptology, a code is a method used to encrypt a message that operates at the level of meaning; that is, words or phrases are converted into something else. A code ...
The purpose of channel coding theory is to find codes which transmit quickly, contain many valid code words and can correct or at least detect many errors. While not mutually exclusive, performance in these areas is a trade-off. So, different codes are optimal for different applications.
Codes generally substitute different length strings of characters in the output, while ciphers generally substitute the same number of characters as are input. A code maps one meaning with another. Words and phrases can be coded as letters or numbers. Codes typically have direct meaning from input to key. Codes primarily function to save time.
Deciphering the encrypted text character X (which is a number) is as simple as looking up the Xth word of the Declaration of Independence and using the first letter of that word as the decrypted character. Another homophonic cipher was described by Stahl [2] [3] and was one of the first [citation needed] attempts to provide for computer ...
Some work defines code-mixing as the placing or mixing of various linguistic units (affixes, words, phrases, clauses) from two different grammatical systems within the same sentence and speech context, while code-switching is the placing or mixing of units (words, phrases, sentences) from two codes within the same speech context.
The general social situations and behavioral co-occurrences in which speakers prefer one code over another are termed domains. Domain specificity has been expanded to include the idea of metaphorical code-switching. Charles A. Ferguson's 1959 work on diglossia served as a foundation for Joshua Fishman's later work on domain specificity ...
