Summary
Bits ordering in big and little endian.

"In little endian, the low order byte of an object appears at the lowest address in memory. In big endian, (RISC), the high order byte of an object appears at the lowest address in memory. The asm bswap instruction converts between the two data formats." Source = The art of assembly language, Volume 1 By Randall Hyde
