    8 bits – (a.k.a. octet or octad(e)) on many computer architectures. – equivalent to 1 "word" on 8-bit computers (Apple II, Atari 8-bit computers, Commodore 64, etc.). – the "word size" for 8-bit console systems including: Atari 2600, Nintendo Entertainment System. 10 1: decabit 10 bits – minimum bit length to store a single byte with ...

  3. 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.

  4. 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 ...

  5. Kilobyte - Wikipedia

    en.wikipedia.org/wiki/Kilobyte

    The binary meaning of the kilobyte for 1024 bytes typically uses the symbol KB, with an uppercase letter K. The B is sometimes omitted in informal use. For example, a processor with 65,536 bytes of cache memory might be said to have "64 K" of cache. In this convention, one thousand and twenty-four kilobytes (1024 KB) is equal to one megabyte (1 ...

  6. Bit - Wikipedia

    For example, a DRAM chip that is specified (and advertised) as having "1 GB" of capacity has bytes of capacity. As at 2022, the difference between the popular understanding of a memory system with "8 GB" of capacity, and the SI-correct meaning of "8 GB" was still causing difficulty to software designers. [14]

  7. Word (computer architecture) - Wikipedia

    en.wikipedia.org/wiki/Word_(computer_architecture)

    For example, the PDP-10 byte pointer contained the size of the byte in bits (allowing different-sized bytes to be accessed), the bit position of the byte within the word, and the word address of the data. Instructions could automatically adjust the pointer to the next byte on, for example, load and deposit (store) operations.

  9. Megabyte - Wikipedia

    1 MB = 1 024 000 bytes (= 1000×1024 B) is the definition used to describe the formatted capacity of the 1.44 MB 3.5-inch HD floppy disk, which actually has a capacity of 1 474 560 bytes. [ 5 ] Randomly addressable semiconductor memory doubles in size for each address lane added to an integrated circuit package, which favors counts that are ...
