What is the difference between Big Endian and Little Endian? Write each of
the following base 16 numbers in both big and little endian format. Indicate
the memory address of each byte.
• 0xA0B18233
• 0xDEADBEEF
• 0x21426981

Answer 1

Assuming that the memory addresses are 0, 1, 2 and 3
1)  0xA0B18233
Big Endian:
-------------
Memory: 0  1  2  3
Value:  A0 B1 82 33

Little Endian:
-------------
Memory: 0  1  2  3
Value:  33 82 B1 A0

2)  0xDEADBEEF
Big Endian:
-------------
Memory: 0  1  2  3
Value:  DE AD BE EF

Little Endian:
-------------
Memory: 0  1  2  3
Value:  EF BE AD DE

3)  0x21426981
Big Endian:
-------------
Memory: 0  1  2  3
Value:  21 42 69 81

Little Endian:
-------------
Memory: 0  1  2  3
Value:  81 69 42 21
