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
  • 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
  • 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?
  • Convert byte to string in Java - Stack Overflow
    Because gustafc's answer has a very important point: String(byte[]) constructor uses the System default encoding to convert the byte array into String characters One should not assume that a 0x63 byte value is mapped to the letter 'c' For example, in UTF-16 the letter 'c' is represented by 2 encoding bytes, not one
  • 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
  • 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
  • What are Unicode, UTF-8, and UTF-16? - Stack Overflow
    These two-byte portions come from the BMP numeric range, but are guaranteed by the Unicode standard to be invalid as BMP characters In addition, since UTF-16 has two bytes as its basic unit, it is affected by endianness To compensate, a reserved byte order mark can be placed at the beginning of a data stream which indicates endianness Thus
  • How to convert byte[] to Byte[] and the other way around?
    Step back Look at the bigger picture You're stuck converting byte[] to Byte[] or vice versa because of Java's strict type casing with something like this List< Byte> or List<Byte[]> Now you have byte[] and Byte[] and have to convert This will help Keep all your byte[]s in a list like this: List<byte[]> instead of List< Byte> or List<Byte[]>
  • binary - Why does a byte only have 0 to 255? - Stack Overflow
    Strictly speaking, the term "byte" can actually refer to a unit with other than 256 values It's just that that's the almost universal size From Wikipedia: Historically, a byte was the number of bits used to encode a single character of text in a computer and it is for this reason the basic addressable element in many computer architectures
