A 32-bit register contains the value 0xabcdef12.

1. a) If this register value is written to address 0 via a store word instruction on a little-endian machine, what would the contents of memory locations 0, 1, 2, and 3 look like after the store is complete?

2. b) If we executed a load word instruction to address 0 on a big-endian machine, and the memory contents at addresses 0 thru 3 are what you indicated in part a, what 32-bit value would be loaded into the destination register at the completion of this load instruction?

3. c) Lets say that, instead of a load word instruction, a load byte instruction to address 1 is executed. What would be the 32-bit value loaded into the destination register? Provide an answer for both signed and unsigned versions of load byte.
