    en.wikipedia.org/wiki/List_of_binary_codes

    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.

  3. Scott's rule - Wikipedia

    en.wikipedia.org/wiki/Scott's_Rule

    Scott's rule is widely employed in data analysis software including R, [2] Python [3] and Microsoft Excel where it is the default bin selection method. [ 4 ] For a set of n {\displaystyle n} observations x i {\displaystyle x_{i}} let f ^ ( x ) {\displaystyle {\hat {f}}(x)} be the histogram approximation of some function f ( x ) {\displaystyle f ...

  4. Binary-code compatibility - Wikipedia

    en.wikipedia.org/wiki/Binary-code_compatibility

    Binary-code compatibility (binary compatible or object-code compatible) is a property of a computer system, meaning that it can run the same executable code, typically machine code for a general-purpose computer central processing unit (CPU), that another computer system can run.

    Binary code, the representation of text and data using only the digits 1 and 0; Bit, or binary digit, the basic unit of information in computers; Binary file, composed of something other than human-readable text Executable, a type of binary file that contains machine code for the computer to execute

  7. Aiken code - Wikipedia

    en.wikipedia.org/wiki/Aiken_code

    The Aiken code differs from the standard 8421 BCD code in that the Aiken code does not weight the fourth digit as 8 as with the standard BCD code but with 2. Aiken code (symmetry property) Aiken code in hexadecimal coding. The following weighting is obtained for the Aiken code: 2-4-2-1. One might think that double codes are possible for a ...

  8. Binary translation - Wikipedia

    en.wikipedia.org/wiki/Binary_translation

    Code is only translated as it is discovered and when possible, and branch instructions are made to point to already translated and saved code (memoization). Dynamic binary translation differs from simple emulation (eliminating the emulator's main read-decode-execute loop—a major performance bottleneck), paying for this by large overhead ...

    On 3 November 2014, Mastercard announced that they were introducing a new series of BIN ranges that begin with a "2" (222100–272099). The "2" series BINs will be processed the same as the "51–55" series BINs are today. They became active 14 October 2016. On 23 July 2014 JSC NSPK was established in the Russian Federation.
