Endian, or endianness, refers to the ordering of bytes within the multi-byte words of digital data in various computer systems.
==Description==
A system which stores the most significant (first) byte of data at the lowest (first) memory address would be considered big-endian (BE), whereas a system which stores the least significant (last) byte of data at the lowest (first) memory address would be considered little-endian (LE).. 2007-08-14.
===Origins===
The term comes from 's book , and was codified in a technical paper published in 1980 by computer scientist ."On Holy Wars and a Plea for Peace" by Danny Cohen, USC/ISI IEN 137, 1980-04-01.
===History at Apple===
The 6502 processors used in the early Apple II series were all little-endian, as were Intel processors used in IBM PCs and later Macs. However, the first Macintosh models based on 68K processors were big-endian. RISC processors used by Apple in PowerPC and ARM-based systems have all been , which means that the system can handle the data both ways.Is Apple's new M1 processor "big-endian" (like the original Motorola microprocessor), or "little-endian" (like the Intel processor)?, Quora.
