  2. Orders of magnitude (data) - Wikipedia

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

    4,704 bits (588 bytes) – uncompressed single-channel frame length in standard MPEG audio (75 frames per second and per channel), with medium quality 8-bit sampling at 44,100 Hz (or 16-bit sampling at 22,050 Hz) kilobyte (kB, KB) 8,000 bits (1,000 bytes) 2 13: kibibyte (KiB) 8,192 bits (1,024 bytes) – RAM capacity of a ZX81 and a ZX80.

  3. Units of information - Wikipedia

    en.wikipedia.org/wiki/Units_of_information

    In particular, if b is a positive integer, then the unit is the amount of information that can be stored in a system with b possible states. When b is 2, the unit is the shannon, equal to the information content of one "bit". A system with 8 possible states, for example, can store up to log 2 8 = 3 bits of information. Other units that have ...

  4. Byte - Wikipedia

    en.wikipedia.org/wiki/Byte

    The byte is a unit of digital information that most commonly consists of eight bits.Historically, the byte was the number of bits used to encode a single character of text in a computer [1] [2] and for this reason it is the smallest addressable unit of memory in many computer architectures.

  5. C data types - Wikipedia

    en.wikipedia.org/wiki/C_data_types

    The element pc requires ten blocks of memory of the size of pointer to char (usually 40 or 80 bytes on common platforms), but element pa is only one pointer (size 4 or 8 bytes), and the data it refers to is an array of ten bytes (sizeof * pa == 10).

  6. Kilobyte - Wikipedia

    en.wikipedia.org/wiki/Kilobyte

    In this case, this text is 10^3 bytes long, but if you were to add 24 extra characters to this string, it would be 2^10 bytes long, which is used in some fields such as information technology. Each character in this string (which includes the quotation marks at the end, by the way) is exactly one byte long, which is 8 bits.

  7. Bit - Wikipedia

    en.wikipedia.org/wiki/Bit

    A group of eight bits is called one byte, but historically the size of the byte is not strictly defined. [2] Frequently, half, full, double and quadruple words consist of a number of bytes which is a low power of two. A string of four bits is usually a nibble.

  8. 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.

  9. Data-rate units - Wikipedia

    en.wikipedia.org/wiki/Data-rate_units

    The ISQ symbols for the bit and byte are bit and B, respectively.In the context of data-rate units, one byte consists of 8 bits, and is synonymous with the unit octet.The abbreviation bps is often used to mean bit/s, so that when a 1 Mbps connection is advertised, it usually means that the maximum achievable bandwidth is 1 Mbit/s (one million bits per second), which is 0.125 MB/s (megabyte per ...
