What Does Endian Mean?

Endian refers to how the order of bytes in a multi-byte value is perceived or acted upon. It is the system of ordering the individual elements in a digital word in a computer’s memory as well as describing the order of transmission of byte data over a digital link. Digital words may be represented as little-endian or big-endian.

Techopedia Explains Endian

Endian or endianness is the byte order chosen for all digital computing made in a specific computer system and dictates the architecture and low-level programming approach to be used for that system. Though today, endianness is not such a large concern for system compatibility since it can always be circumvented in the lower levels so that high-level language programmers and users are already abstracted from the endianness of the system.
