Byte Ordering: The direction in which a computer's PROCESSOR reads the BYTES that make up each WORD stored in its memory. Some machines are designed to read the byte at the lower address first, so that OC 77 is read as OC77hor 3191decimal, while others read the higher address first, so that OC 77 is read as 770Ch or 30476 decimal A difference in byte ordering represents the greatest possible degree of incompatibility, since not only can two such computers not execute each other's programs, but they cannot even agree on the value of any particular instruction or data item.
