  2. Kilobyte - Wikipedia

    en.wikipedia.org/wiki/Kilobyte

    The kilobyte is a multiple of the unit byte for digital information.. The International System of Units (SI) defines the prefix kilo as a multiplication factor of 1000 (10 3); therefore, one kilobyte is 1000 bytes. [1]

  3. Units of information - Wikipedia

    en.wikipedia.org/wiki/Units_of_information

    1024 bytes = 1 KiB: A block size in some older UNIX filesystems; 2048 bytes = 2 KiB: A CD-ROM sector; 4096 bytes = 4 KiB: A memory page in x86 (since Intel 80386) and many other architectures, also the modern Advanced Format hard disk drive sector size. 4 kB: About one page of text from a novel; 120 kB: The text of a typical pocket book

    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.

  5. File size - Wikipedia

    en.wikipedia.org/wiki/File_size

    Typically, file size is expressed in units based on byte. A large value is often expressed with a metric prefix (as in megabyte and gigabyte ) or a binary prefix (as in mebibyte and gibibyte ). [ 1 ]

  6. List of interface bit rates - Wikipedia

    en.wikipedia.org/wiki/List_of_interface_bit_rates

    On devices like modems, bytes may be more than 8 bits long because they may be individually padded out with additional start and stop bits; the figures below will reflect this. Where channels use line codes (such as Ethernet , Serial ATA , and PCI Express ), quoted rates are for the decoded signal.

  7. 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 ...

  8. Bit - Wikipedia

    en.wikipedia.org/wiki/Bit

    Like the byte, the number of bits in a word also varies with the hardware design, and is typically between 8 and 80 bits, or even more in some specialized computers. In the early 21st century, retail personal or server computers have a word size of 32 or 64 bits.

  9. Byte - Wikipedia

    en.wikipedia.org/wiki/Byte

    The byte is a unit of digital information that most commonly consists of eight bits. 1 byte (B) = 8 bits (bit).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.
