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?]

  • 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
  • How many characters can you store with 1 byte? - Stack Overflow
    1 byte = 8 bits So, does this mean 1 byte can only hold one character? E g : "16" uses 2 bytes , "9" uses 1 byte , "a" uses 1 byte, "b" uses 1 byte and if tiny int has range of 0-255, does this mean it can be stored with 255 char? what is storage of 1 tiny int (1) 2 tiny int (2) what will be the range 0-10
  • 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
  • Difference between BYTE and CHAR in column datatypes
    BYTE is the default if you do not specify BYTE or CHAR So if you write NAME VARCHAR2(4000 BYTE) and use Unicode(UTF-16) character encoding then only 2000 characters can be accommodated in NAME That means the size limit on the variable is applied in BYTES and it depends on the character encoding that how many characters can be accommodated in
  • Convert integer into byte array (Java) - Stack Overflow
    This is a perfectly fine answer Note that big-endian is the specified default, and the methods are "chainable", and the position argument is optional, so it all reduces to: byte[] result = ByteBuffer allocate(4) putInt(0xAABBCCDD) array(); Of course, if you're doing this repeatedly and concatenating all the results together (which is common when you're doing this kind of thing), allocate a
  • Difference between Big Endian and little Endian Byte order
    Byte endianness (big or little) needs to be specified for Unicode UTF-16 encoding because for character codes that use more than a single byte, there is a choice of whether to read write the most significant byte first or last Unicode UTF-16, since they are variable-length encodings (i e each char can be represented by one or several bytes
  • java - why byte += 1 compile but byte = byte - Stack Overflow
    operands of type byte and short are automatically promoted to int before being handed to the operators so when you do byte b= b + 1; it considers it "int" as an operation is performed on byte value so to avoid this we use b+=1; here it is automatically typecasted to byte
  • Whats the difference between a word and byte? - Stack Overflow
    The C++ standard defines ‘byte’ as “Addressable unit of data large enough to hold any member of the basic character set of the execution environment ” What this means is that the byte consists of at least enough adjacent bits to accommodate the basic character set for the implementation
  • java - Easy way to concatenate two byte arrays - Stack Overflow
    byte[] a; byte[] b; byte[] result = concat(a, b); It will also work for concatenating 3, 4, 5 arrays, etc Doing it this way gives you the advantage of fast arraycopy code which is also very easy to read and maintain
