Applies to: general, c
Endianness is the order in which a multi-byte number is stored in memory. Big-endian puts the most significant byte first; little-endian puts the least significant byte first. It matters when reading binary files or sending data between machines.
0x12345678 big-endian: 12 34 56 78 little-endian: 78 56 34 12
