When bytes are grouped (Word, Double Word, Quadruple Word), the ordering can be logical : BIG Endian (first byte is the byte with higher values) or reversed LITTLE Endian (first byte is the byte with lower values).

Endianness is based on the history of computers and operating systems, and the type of processor used. As 8 bits registers processors do not care about endianness (they had to only handle 1 byte), followers have to.

Windows is mostly « Little Endian » based and Mac OS X mostly « Big Endian » based. Tyrhex shows the two ordering for the bytes values and automatically handles the right ordering when interpreting date and time values.
