15. Consider a computer that uses little-endian numbering. If a 32-bit operand resides at decimal address N, what is the address of: (a) The most significant byte (b) The 16-bit operand corresponding to the most significant half 16. If bytes within a word are assigned addresses that increase from the most to least signifi- cant byte, the computer is said to use: (a) Little-endian numbering (b) Big-endian numbering
