  2. Binary number - Wikipedia

    en.wikipedia.org/wiki/Binary_number

    Binary is also easily converted to the octal numeral system, since octal uses a radix of 8, which is a power of two (namely, 2 3, so it takes exactly three binary digits to represent an octal digit). The correspondence between octal and binary numerals is the same as for the first eight digits of hexadecimal in the table above.

  3. Binary code - Wikipedia

    en.wikipedia.org/wiki/Binary_code

    Binary-coded decimal (BCD) is a binary encoded representation of integer values that uses a 4-bit nibble to encode decimal digits. Four binary bits can encode up to 16 distinct values; but, in BCD-encoded numbers, only ten values in each nibble are legal, and encode the decimal digits zero, through nine.

  4. Bit - Wikipedia

    en.wikipedia.org/wiki/Bit

    A contiguous group of binary digits is commonly called a bit string, a bit vector, or a single-dimensional (or multi-dimensional) bit array. A group of eight bits is called one byte, but historically the size of the byte is not strictly defined. [2]

    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

  6. Bit numbering - Wikipedia

    en.wikipedia.org/wiki/Bit_numbering

    A diagram showing how manipulating the least significant bits of a color can have a very subtle and generally unnoticeable effect on the color. In this diagram, green is represented by its RGB value, both in decimal and in binary. The red box surrounding the last two bits illustrates the least significant bits changed in the binary representation.

  7. Binary data - Wikipedia

    en.wikipedia.org/wiki/Binary_data

    A binary variable is a random variable of binary type, meaning with two possible values. Independent and identically distributed (i.i.d.) binary variables follow a Bernoulli distribution , but in general binary data need not come from i.i.d. variables.

  8. List of numeral systems - Wikipedia

    en.wikipedia.org/wiki/List_of_numeral_systems

    A binary clock might use LEDs to express binary values. In this clock, each column of LEDs shows a binary-coded decimal numeral of the traditional sexagesimal time.. The common names are derived somewhat arbitrarily from a mix of Latin and Greek, in some cases including roots from both languages within a single name. [27]

  9. Numeral system - Wikipedia

    en.wikipedia.org/wiki/Numeral_system

    In computers, the main numeral systems are based on the positional system in base 2 (binary numeral system), with two binary digits, 0 and 1. Positional systems obtained by grouping binary digits by three (octal numeral system) or four (hexadecimal numeral system) are commonly used.
