Endianness is primarily expressed as big-endian (BE) or little-endian (LE), terms introduced by Danny Cohen into computer science for data ordering in an Internet Experiment Note published in 1980. [1] The adjective endian has its origin in the writings of 18th century Anglo-Irish writer Jonathan Swift.
BER: variable-length big-endian binary representation (up to 2 2 1024 bits); PER Unaligned: a fixed number of bits if the integer type has a finite range; a variable number of bits otherwise; PER Aligned: a fixed number of bits if the integer type has a finite range and the size of the range is less than 65536; a variable number of octets ...

If the BOM is missing, RFC 2781 recommends [e] that big-endian (BE) encoding be assumed. In practice, due to Windows using little-endian (LE) order by default, many applications assume little-endian encoding. It is also reliable to detect endianness by looking for null bytes, on the assumption that characters less than U+0100 are very common.
Most platforms use the IEEE representation for floating-point numbers. [...] To assist you in reading and/or writing transport files, we are providing routines to convert from IEEE representation (either big endian or little endian) to transport representation and back again." [13] Code for IBM's format is also available under LGPLv2.1. [15]
The address bytes are arranged in big-endian format. Data - a sequence of 2n hex digits, for n bytes of the data. For S1/S2/S3 records, a maximum of 32 bytes per record is typical since it will fit on an 80 character wide terminal screen, though 16 bytes would be easier to visually decode each byte at a specific address.
The BOM for little-endian UTF-32 is the same pattern as a little-endian UTF-16 BOM followed by a UTF-16 NUL character, an unusual example of the BOM being the same pattern in two different encodings. Programmers using the BOM to identify the encoding will have to decide whether UTF-32 or UTF-16 with a NUL first character is more likely.
