byte
n 1: a sequence of 8 bits (enough to represent one character of
alphanumeric data) processed as a single unit of
information

/bi:t/ (B) A component in the machine {data hierarchy}
larger than a {bit} and usually smaller than a {word}; now
nearly always eight bits and the smallest addressable unit of
storage. A byte typically holds one {character}.

A byte may be 9 bits on 36-bit computers. Some older
architectures used "byte" for quantities of 6 or 7 bits, and
the PDP-10 and IBM 7030 supported "bytes" that were actually
{bit-fields} of 1 to 36 (or 64) bits! These usages are now
obsolete, and even 9-bit bytes have become rare in the general
trend toward power-of-2 word sizes.

The term was coined by Werner Buchholz in 1956 during the
early design phase for the {IBM} {Stretch} computer. It was a
mutation of the word "bite" intended to avoid confusion with
"bit". In 1962 he described it as "a group of bits used to
encode a character, or the number of bits transmitted in
parallel to and from input-output units". The move to an
8-bit byte happened in late 1956, and this size was later
adopted and promulgated as a standard by the {System/360}
{operating system} (announced April 1964).

James S. Jones adds:

I am sure I read in a mid-1970's brochure by IBM that outlined
the history of computers that BYTE was an acronym that stood
for "Bit asYnchronous Transmission E..?" which related to
width of the bus between the Stretch CPU and its CRT-memory
(prior to Core).

Terry Carr says:

In the early days IBM taught that a series of bits transferred
together (like so many yoked oxen) formed a Binary Yoked
Transfer Element (BYTE).

[True origin? First 8-bit byte architecture?]

  • . net - What is a byte [] array? - Stack Overflow
    21 In NET, a byte is basically a number from 0 to 255 (the numbers that can be represented by eight bits) So, a byte array is just an array of the numbers 0 - 255 At a lower level, an array is a contiguous block of memory, and a byte array is just a representation of that memory in 8-bit chunks
  • How do I initialize a byte array in Java? - Stack Overflow
    I have to store some constant values (UUIDs) in byte array form in java, and I'm wondering what the best way to initialize those static arrays would be This is how I'm currently doing it, but I feel
  • c# - byte [] to hex string - Stack Overflow
    How do I convert a byte[] to a string? Every time I attempt it, I get System Byte[] instead of the value Also, how do I get the value in Hex instead of a decimal?
  • Can endianness refer to the order of bits in a byte?
    Endianness and byte order When a value larger than byte is stored or serialized into multiple bytes, the choice of the order in which the component bytes are stored is called byte order, or endian, or endianness Historically, there have been three byte orders in use: "big-endian", "little-endian", and "PDP-endian" or "middle-endian"
  • Is there byte data type in C++? - Stack Overflow
    39 No there is no byte data type in C++ However you could always include the bitset header from the standard library and create a typedef for byte:
  • How to convert byte[] to Byte[] and the other way around?
    How to convert byte[] to Byte[] and also Byte[] to byte[], in the case of not using any 3rd party library? Is there a way to do it fast just using the standard library?
  • java - What do we mean by Byte array? - Stack Overflow
    A byte is 8 bits (binary data) A byte array is an array of bytes (tautology FTW!) You could use a byte array to store a collection of binary data, for example, the contents of a file The downside to this is that the entire file contents must be loaded into memory For large amounts of binary data, it would be better to use a streaming data type if your language supports it

  • c# - Why does byte + byte = int? - Stack Overflow
    long + long = long float + float = float double + double = double So why not: byte + byte = byte short + short = short? A bit of background: I am performing a long list of calculations on "small numbers" (i e < 8) and storing the intermediate results in a large array Using a byte array (instead of an int array) is faster (because of cache hits)
