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).

  • 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"
  • How to fix: UnicodeDecodeError: ascii codec cant decode byte
    UnicodeDecodeError: 'ascii' codec can't decode byte generally happens when you try to convert a Python 2 x str that contains non-ASCII to a Unicode string without specifying the encoding of the original string In brief, Unicode strings are an entirely separate type of Python string that does not contain any encoding
  • byte - How many bits is a word? - Stack Overflow
    If a character is 8 bits, or 1 byte, then a WORD must be at least 2 characters, so 16 bits or 2 bytes Traditionally, you might think of a word as a varying number of characters, but in a computer, everything that is calculable is based on static rules Besides, a computer doesn't know what letters and symbols are, it only knows how to count
  • Error UnicodeDecodeError: utf-8 codec cant decode byte 0xff in . . .
    Python tries to convert a byte-array (a bytes which it assumes to be a utf-8-encoded string) to a unicode string (str) This process of course is a decoding according to utf-8 rules When it tries this, it encounters a byte sequence which is not allowed in utf-8-encoded strings (namely this 0xff at position 0) Since you did not provide any code we could look at, we only could guess on the
  • python - UnicodeDecodeError: utf8 codec cant decode byte 0xa5 in . . .
    data decode() # UnicodeDecodeError: 'utf-8' codec can't decode byte 0x89 in position 0: invalid start byte You probably want to read the image into a numeric array in the first place, so the solution is to use a dedicated image reader module instead and convert the data into an array without the middleman process of decoding a bytes
  • UnicodeDecodeError, invalid continuation byte - Stack Overflow
    Latin-1 is a single byte encoding family so everything in it should be defined in UTF-8 But why sometime Latin-1 wins?
  • Converting string to byte array in C# - Stack Overflow
    If you already have a byte array then you will need to know what type of encoding was used to make it into that byte array For example, if the byte array was created like this:
  • Difference between Big Endian and little Endian Byte order
    What is the difference between Big Endian and Little Endian Byte order ? Both of these seem to be related to Unicode and UTF16 Where exactly do we use this?
  • . 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 you convert a byte array to a hexadecimal string, and vice versa?
    That value is then added to the resulting string output in some fashion For a long time byte manipulation, potentially harder to read by some developers, was the top-performing approach Your best bet is still going to be finding some representative data and trying it out in a production-like environment
