  2. Binary number - Wikipedia

    en.wikipedia.org/wiki/Binary_number

    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.Because of its straightforward implementation in digital electronic circuitry using logic gates, the binary system is used by almost all modern computers and computer-based devices, as a preferred system of use, over various other human techniques of communication, because ...

  3. Bit numbering - Wikipedia

    en.wikipedia.org/wiki/Bit_numbering

    Least significant bit first means that the least significant bit will arrive first: hence e.g. the same hexadecimal number 0x12, again 00010010 in binary representation, will arrive as the (reversed) sequence 0 1 0 0 1 0 0 0.

  4. Binary code - Wikipedia

    en.wikipedia.org/wiki/Binary_code

    The word 'Wikipedia' represented in ASCII binary code, made up of 9 bytes (72 bits). 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 ...

  5. List of binary codes - Wikipedia

    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.

  6. Computer number format - Wikipedia

    en.wikipedia.org/wiki/Computer_number_format

    Computer engineers often need to write out binary quantities, but in practice writing out a binary number such as 1001001101010001 is tedious and prone to errors. Therefore, binary quantities are written in a base-8, or "octal", or, much more commonly, a base-16, "hexadecimal" (hex), number format. In the decimal system, there are 10 digits, 0 ...

  7. Binary - Wikipedia

    en.wikipedia.org/wiki/Binary

    Binary number, a representation of numbers using only two values (0 and 1) for each digit; Binary function, a function that takes two arguments; Binary operation, a mathematical operation that takes two arguments; Binary relation, a relation involving two elements; Binary-coded decimal, a method for encoding for decimal digits in binary sequences

  8. Binary integer decimal - Wikipedia

    en.wikipedia.org/wiki/Binary_Integer_Decimal

    In the binary integer decimal (BID) encoding, it is encoded as a binary number. Format. Using the fact that 2 10 = 1024 is only slightly more than 10 3 = 1000, ...

  9. Finger binary - Wikipedia

    en.wikipedia.org/wiki/Finger_binary

    Finger binary is a system for counting and displaying binary numbers on the fingers of either or both hands. Each finger represents one binary digit or bit . This allows counting from zero to 31 using the fingers of one hand, or 1023 using both: that is, up to 2 5 −1 or 2 10 −1 respectively.
