  2. Binary code - Wikipedia

    en.wikipedia.org/wiki/Binary_code

    A binary code represents text, computer processor instructions, or any other data using a two-symbol system. The two-symbol system used is often "0" and "1" from the binary number system. The binary code assigns a pattern of binary digits, also known as bits, to each character, instruction, etc.

  3. Binary number - Wikipedia

    en.wikipedia.org/wiki/Binary_number

    A binary number is a number expressed in the base -2 numeral system or binary numeral system, a method of mathematical expression which uses only two symbols: typically "0" ( zero) and "1" ( one ). 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.

  4. Morse code - Wikipedia

    en.wikipedia.org/wiki/Morse_code

    Morse code is a method used in telecommunication to encode text characters as standardized sequences of two different signal durations, called dots and dashes, or dits and dahs. [3] [4] Morse code is named after Samuel Morse, one of the early developers of the system adopted for electrical telegraphy .

  5. Braille ASCII - Wikipedia

    en.wikipedia.org/wiki/Braille_ASCII

    Overview. Braille ASCII uses the 64 ASCII characters between 32 and 95 inclusive. All capital letters in ASCII correspond to their equivalent values in uncontracted English Braille. Note however that, unlike standard print, there is only one braille symbol for each letter of the alphabet.

  6. Binary translation - Wikipedia

    en.wikipedia.org/wiki/Binary_translation

    A translator using static binary translation aims to convert all of the code of an executable file into code that runs on the target architecture without having to run the code first, as is done in dynamic binary translation. This is very difficult to do correctly, since not all the code can be discovered by the translator.

  7. Arecibo message - Wikipedia

    en.wikipedia.org/wiki/Arecibo_message

    The numbers from 1 to 10 appear in binary format, to be read from the top down. The bottom row contains markers which indicate the column from which the binary code for each number is intended to begin.

  8. Binary-coded decimal - Wikipedia

    en.wikipedia.org/wiki/Binary-coded_decimal

    In computing and electronic systems, binary-coded decimal ( BCD) is a class of binary encodings of decimal numbers where each digit is represented by a fixed number of bits, usually four or eight. Sometimes, special bit patterns are used for a sign or other indications (e.g. error or overflow).

  9. Cyrillic script in Unicode - Wikipedia

    en.wikipedia.org/wiki/Cyrillic_script_in_Unicode

    As of Unicode version 15.1, Cyrillic script is encoded across several blocks : Cyrillic: U+0400–U+04FF, 256 characters. Cyrillic Supplement: U+0500–U+052F, 48 characters. Cyrillic Extended-A: U+2DE0–U+2DFF, 32 characters. Cyrillic Extended-B: U+A640–U+A69F, 96 characters.

  10. Bitwise operation - Wikipedia

    en.wikipedia.org/wiki/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.

  11. List of binary codes - Wikipedia

    en.wikipedia.org/wiki/List_of_binary_codes

    For example, "NO U" in Morse code is " — . — — — . . — ", which could be represented in binary as "1110100011101110111000000010101110". If, however, Morse code is represented as a ternary system, "NO U" would be represented as "1110|10|00|1110|1110|1110|00|00|00|10|10|1110".
