In big-endian format, the most significant byte of a word is stored at the lowest numbered byte and the least significant byte at the highest numbered byte. Byte 0 of the memory system is therefore connected to data lines 31 to 24.
Big-endian format is shown in Figure 2.1.
Most significant byte is at lowest address
Word is addressed by byte address of most significant byte.
