Question

What is big-endian order of 78563412h? (first column represents the address)?

Answer 1

Answer -

Big Endian Byte Order: The most significant byte (the "big end") of the data is placed at the byte with the lowest address. ... The most significant byte is 0x12; the least significant is 0x78. Within a byte the order of the bits is the same for all computers (no matter how the bytes themselves are arranged).
