International Morse code encodes the 26 basic Latin letters A to Z, one accented Latin letter ( É ), the Arabic numerals, and a small set of punctuation and procedural signals ( prosigns ). There is no distinction between upper and lower case letters. [1]
A telegraph code is one of the character encodings used to transmit information by telegraphy. Morse code is the best-known such code. Telegraphy usually refers to the electrical telegraph, but telegraph systems using the optical telegraph were in use before that. A code consists of a number of code points, each corresponding to a letter of the ...
X. Y. Z. The tap code, sometimes called the knock code, is a way to encode text messages on a letter-by-letter basis in a very simple way. The message is transmitted using a series of tap sounds, hence its name. [1] The tap code has been commonly used by prisoners to communicate with each other. The method of communicating is usually by tapping ...
This table lists all two-letter codes (set 1), one per language for ISO 639 macrolanguage, and some of the three-letter codes of the other sets, formerly parts 2 and 3.
These letters have been used for multiple purposes. Originally, they referred to the leading letters of telephone exchange names.In the mid-20th century United States, before the switch to All-Number Calling, telephone numbers had seven digits including a two-digit prefix which was expressed in letters rather than digits, e.g.; KL5-5445.

Therefore, a word like action would encode the number 762 (/k/-/ʃ/-/n/), not 712 (k-t-n). Double letters are disregarded when not pronounced separately, e.g. muddy encodes 31 (/m/-/d/), not 311, but midday encodes 311 (/m/-/d/-/d/) while accept encodes 7091 (/k/-/s/-/p/-/t/) since the ds and cs are pronounced separately.
Character encoding is the process of assigning numbers to graphical characters, especially the written characters of human language, allowing them to be stored, transmitted, and transformed using digital computers. [1] The numerical values that make up a character encoding are known as "code points" and collectively comprise a "code space", a ...
Further words can be made by treating some of the decimal numbers as letters - the digit " 0 " can represent the letter "O", and " 1 " can represent the letters "I" or "L". Less commonly, " 5 " can represent "S", " 7 " represent "T", " 12 " represent "R" and " 6 " or " 9 " can represent "G" or "g", respectively.
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.
