Morse code. Morse code is a method used in telecommunication to encode text characters as standardized sequences of two different signal durations, called dots and dashes, or dits and dahs. [3] [4] Morse code is named after Samuel Morse, one of the early developers of the system adopted for electrical telegraphy .
In cryptography, a Caesar cipher, also known as Caesar's cipher, the shift cipher, Caesar's code, or Caesar shift, is one of the simplest and most widely known encryption techniques. It is a type of substitution cipher in which each letter in the plaintext is replaced by a letter some fixed number of positions down the alphabet.
The pigpen cipher (alternatively referred to as the masonic cipher, Freemason's cipher, Rosicrucian cipher, Napoleon cipher, and tic-tac-toe cipher) [2] [3] is a geometric simple substitution cipher, which exchanges letters for symbols which are fragments of a grid. The example key shows one way the letters can be assigned to the grid.
ISO 639 is a standardized nomenclature used to classify languages. [1] Each language is assigned a two-letter (set 1) and three-letter lowercase abbreviation (sets 2–5). [2] Part 1 of the standard, ISO 639-1 defines the two-letter codes, and Part 3 (2007), ISO 639-3, defines the three-letter codes, aiming to cover all known natural languages ...
The International Radiotelephony Spelling Alphabet or simply Radiotelephony Spelling Alphabet, commonly known as the NATO phonetic alphabet, is the most widely used set of clear-code words for communicating the letters of the Roman alphabet. Technically a radiotelephonic spelling alphabet, it goes by various names, including NATO spelling ...
The naming convention for FM translators includes their three-digit FM channel number (from 200 to 300), followed by two sequentially assigned letters – for example, K237FR. The translator may identify itself hourly by voice or Morse code. The primary station may instead choose to identify all its translators together; if it does so, the ...
Google Translate is a web-based free-to-user translation service developed by Google in April 2006. [11] It translates multiple forms of texts and media such as words, phrases and webpages. Originally, Google Translate was released as a statistical machine translation service. [11] The input text had to be translated into English first before ...

For a number , if (), (), …, (), represent the digits of the code word representing then we have: N = ∑ i = 0 k − 1 d ( i ) F ( i + 2 ) , and d ( k − 1 ) = d ( k ) = 1. {\displaystyle N=\sum _{i=0}^{k-1}d(i)F(i+2),{\text{ and }}d(k-1)=d(k)=1.\!}
Number translation service. A number translation service translates a dialled telephone number, typically beginning 08 in the UK to a geographical 'connect number' beginning 01 or 02 in the UK. The connect number may be changed without changing the published dialled number.
