Those methods may use fixed-width or variable-width strings. In a fixed-width binary code, each letter, digit, or other character is represented by a bit string of the same length; that bit string, interpreted as a binary number, is usually displayed in code tables in octal, decimal or hexadecimal notation.
Bitwise operation. In computer programming, a bitwise operation operates on a bit string, a bit array or a binary numeral (considered as a bit string) at the level of its individual bits. It is a fast and simple action, basic to the higher-level arithmetic operations and directly supported by the processor.
A bit array (also known as bitmask, [ 1] bit map, bit set, bit string, or bit vector) is an array data structure that compactly stores bits. It can be used to implement a simple set data structure. A bit array is effective at exploiting bit-level parallelism in hardware to perform operations quickly. A typical bit array stores kw bits, where w ...
Base64. In computer programming, Base64 is a group of binary-to-text encoding schemes that transforms binary data into a sequence of printable characters, limited to a set of 64 unique characters. More specifically, the source binary data is taken 6 bits at a time, then this group of 6 bits is mapped to one of 64 unique characters.
GB 18030 – A full-Unicode variable-length code designed for compatibility with older Chinese multibyte encodings; Huffman coding – A technique for expressing more common characters using shorter bit strings than are used for less common characters; Data compression systems such as Lempel–Ziv–Welch can compress arbitrary binary data ...
Bit length or bit width is the number of binary digits, called bits, necessary to represent an unsigned integer [1] as a binary number. Formally, the bit length of a natural number is = ⌈ (+) ⌉ where is the binary logarithm and ⌈ ⌉ is the ceiling function.
(Hyper)cube of binary strings of length 3. Strings admit the following interpretation as nodes on a graph, where k is the number of symbols in Σ: Fixed-length strings of length n can be viewed as the integer locations in an n-dimensional hypercube with sides of length k-1. Variable-length strings (of finite length) can be viewed as nodes on a ...
A string of four bits is usually a nibble. In information theory, one bit is the information entropy of a random binary variable that is 0 or 1 with equal probability, [3] or the information that is gained when the value of such a variable becomes known. [4] [5] As a unit of information, the bit is also known as a shannon, [6] named after ...
