Swap endianness between big-endian & little-endian
Endianness is the order of bytes in each word in a binary string primarily expressed as big-endian or little-endian.
This article is a work in progress.
Words & endianness
In computing, a word is the natural unit of data (fixed number of bytes) used by a particular processor design. On a big-endian (BE) system the most significant byte of a word comes first and the least significant byte last. In contrast, on a little-endian (LE) system, the least-significant byte comes first.
