  2. Byte - Wikipedia

    en.wikipedia.org/wiki/Byte

    Various implementations of C and C++ reserve 8, 9, 16, 32, or 36 bits for the storage of a byte. [67] [68] [f] In addition, the C and C++ standards require that there be no gaps between two bytes. This means every bit in memory is part of a byte. [69] Java's primitive data type byte is defined as eight bits. It is a signed data type, holding ...

  3. 8-bit computing - Wikipedia

    en.wikipedia.org/wiki/8-bit_computing

    An 8-bit register can store 2 8 different values. The range of integer values that can be stored in 8 bits depends on the integer representation used. With the two most common representations, the range is 0 through 255 (2 8 − 1) for representation as an binary number, and −128 (−1 × 2 7) through 127 (2 7 − 1) for representation as two's complement.

  4. Orders of magnitude (data) - Wikipedia

    en.wikipedia.org/wiki/Orders_of_magnitude_(data)

    In the early days of computing, it was used for differing numbers of bits based on convention and computer hardware design, but today means 8 bits. A more accurate, but less commonly used name for 8 bits is octet. Commonly, a decimal SI metric prefix (such as kilo-) is used with bit and byte to express larger sizes (kilobit, kilobyte). But ...

  5. Octet (computing) - Wikipedia

    en.wikipedia.org/wiki/Octet_(computing)

    The international standard IEC 60027-2, chapter 3.8.2, states that a byte is an octet of bits. However, the unit byte has historically been platform-dependent and has represented various storage sizes in the history of computing. Due to the influence of several major computer architectures and product lines, the byte became overwhelmingly ...

  6. Units of information - Wikipedia

    en.wikipedia.org/wiki/Units_of_information

    Historically, a byte was the number of bits used to encode a character of text in the computer, which depended on computer hardware architecture, but today it almost always means eight bits – that is, an octet. An 8-bit byte can represent 256 (2 8) distinct values, such as non-negative integers from 0 to 255, or signed integers from −128 to ...

  7. Computer number format - Wikipedia

    en.wikipedia.org/wiki/Computer_number_format

    A byte is a bit string containing the number of bits needed to represent a character. On most modern computers, this is an eight bit string. Because the definition of a byte is related to the number of bits composing a character, some older computers have used a different bit length for their byte. [2]

  8. Bit - Wikipedia

    en.wikipedia.org/wiki/Bit

    Bits are transmitted one at a time in serial transmission. By contrast, multiple bits are transmitted simultaneously in a parallel transmission. A serial computer processes information in either a bit-serial or a byte-serial fashion. From the standpoint of data communications, a byte-serial transmission is an 8-way parallel transmission with ...

  9. Orders of magnitude (bit rate) - Wikipedia

    en.wikipedia.org/wiki/Orders_of_magnitude_(bit_rate)

    A group of 8 bits (8 bit) constitutes one byte (1 B). The byte is the most common unit of measurement of information ( megabyte , mebibyte , gigabyte , gibibyte , etc.). The decimal SI prefixes kilo , mega etc., are powers of 10.
