This is a list of some binary codes that are (or have been) used to represent text as a sequence of binary digits "0" and "1". Fixed-width binary codes use a set number of bits to represent each character in the text, while in variable-width binary codes, the number of bits may vary from character to character.
This table illustrates an example of decimal value of 149 and the location of LSb. In this particular example, the position of unit value (decimal 1 or 0) is located in bit position 0 (n = 0).
The base-2 numeral system is a positional notation with a radix of 2.Each digit is referred to as a bit, or binary digit.Because of its straightforward implementation in digital electronic circuitry using logic gates, the binary system is used by almost all modern computers and computer-based devices, as a preferred system of use, over various other human techniques of communication, because ...

The "PCM tube" apparatus that Gray patented was made by Raymond W. Sears of Bell Labs, working with Gray and William M. Goodall, who credited Gray for the idea of the reflected binary code. [44] Part of front page of Gray's patent, showing PCM tube (10) with reflected binary code in plate (15)
English: Character tables of binary tetrahedral, octahedral and icosahedral subgroups from "Ueber die Composition der Charaktere einer Gruppe", Sitzungsberichte der Königlich Preussischen Akademie der Wissenschaften zu Berlin, Deutsche Akademie der Wissenschaften zu Berlin, 6 April 1899, page 339
While the International System of Units (SI) defines multiples based on powers of ten (like k = 10 3, M = 10 6, etc.), a different definition is sometimes used in computing, based on powers of two (like k = 2 10, M = 2 20, etc.). This is due to binary nature of current computing systems, making powers of two the simplest to calculate.
A binary-to-text encoding is encoding of data in plain text. More precisely, it is an encoding of binary data in a sequence of printable characters . These encodings are necessary for transmission of data when the communication channel does not allow binary data (such as email or NNTP ) or is not 8-bit clean .
