511 is the natural number following 510 and preceding 512. It is a Mersenne number , being one less than a power of 2: 511 = 2 9 − 1 {\displaystyle 511=2^{9}-1} . [ 1 ] As a result, 511 is a palindromic number and a repdigit in bases 2 (111111111 2 ).
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.
A binary prefix is a unit prefix that indicates a multiple of a unit of measurement by an integer power of two. The most commonly used binary prefixes are kibi (symbol Ki, meaning 2 10 = 1024 ), mebi ( Mi, 2 20 = 1 048 576 ), and gibi ( Gi, 2 30 = 1 073 741 824 ).
The modern binary number system, the basis for binary code, is an invention by Gottfried Leibniz in 1689 and appears in his article Explication de l'Arithmétique Binaire (English: Explanation of the Binary Arithmetic) which uses only the characters 1 and 0, and some remarks on its usefulness. Leibniz's system uses 0 and 1, like the modern ...
The number of binary operations with domain equal to any 4-element set, such as GF(4). 2 40 = 1 099 511 627 776 The binary approximation of the tera-, or 1 000 000 000 000 multiplier, which causes a change of prefix. For example, 1 099 511 627 776 bytes = 1 terabyte [5] or tebibyte. 2 50 = 1 125 899 906 842 624 The binary approximation of the ...
The binary prefixes, as defined by IEC 80000-13, are incorporated into ISO 80000-1, including a note that "SI prefixes refer strictly to powers of 10, and should not be used for powers of 2." [133] In ISO 80000-1, the application of the binary prefixes is not limited to computer technology. For example, 1 KiHz = 1024 Hz.
A child's right to a private life was intruded upon when a judge refused them permission to change their name to a non-binary one they wished to use, appeal judges found. The child told their ...
The International Electrotechnical Commission (IEC) issued a standard that introduces binary prefixes that accurately represent binary sizes without changing the meaning of the standard metric terms. Rather than based on powers of 1000, these are based on powers of 1024 which is a power of 2.
