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
    A byte is 8 bits, and an array of byte, is an array of bytes It really is that simple The thing to keep in mind is that char and byte are different In old C style, a char and byte were basically the same thing In NET, characters are Unicode and can be anywhere from 8-32 bits per character This is where encoding comes into play
  • 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?
  • How do I initialize a byte array in Java? - Stack Overflow
    In Java 6, there is a method doing exactly what you want: private static final byte[] CDRIVES = javax xml bind DatatypeConverter parseHexBinary
  • Is there byte data type in C++? - Stack Overflow
    namespace std { define std::byte enum class byte : unsigned char {}; }; This if your C++ version does not have std::byte will define a byte type in namespace std Normally you don't want to add things to std, but in this case it is a standard thing that is missing std::byte from the STL does much more operations
  • 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
  • java - Byte [] to InputStream or OutputStream - Stack Overflow
    so you end up with a byte[] this could represent any kind of data which may need special types of conversions (character, encrypted, etc) let's pretend you want to write this data as is to a file firstly you could create a ByteArrayInputStream which is basically a mechanism to supply the bytes to something in sequence
  • Why is the range of bytes -128 to 127 in Java? - Stack Overflow
    Without getting into two's complement: 2^8 (since a byte is 8 digits and can have 1 of 2 values) = 256, so the most individual values a byte can represent is 256 so, representing the numbers -128 to -1 is half our range I believe the question here is why is the max positive value 127 rather than 128
  • math - Converting bytes to megabytes - Stack Overflow
    I've seen three ways of doing conversion from bytes to megabytes: megabytes=bytes 1000000 megabytes=bytes 1024 1024 megabytes=bytes 1024 1000 Ok, I think #3 is totally wrong but I have seen it I
  • Initialize a byte array to a certain value, other than the default null?
    That way you could call it like byte[] b = new byte[5000] Initialize(0x20); The extension method would be declared as public static byte[] Initialize(this byte[] array, byte defaultValue) and contain the for loop It should return the array
