Question

question 9 options: assume a computer has 32-bit integers. show how the value 0xcafebabe would be stored sequentially in memory, starting at address 0x100, on both a big endian machine and a little endian machine, assuming that each address holds one byte. write in the ordered one word (e.g. cafebabe) in a blank big-endian in the first, and little-endian in the second blank (ordered left to right)!

Answer 1

On a big endian machine, the value 0xcafebabe would be stored sequentially in memory starting at address 0x100 as follows:

Address: 0x100 0x101 0x102 0x103

Value: ca fe ba be

The most significant byte (MSB) is stored at the lowest memory address (0x100), and the least significant byte (LSB) is stored at the highest memory address (0x103).

On a little endian machine, the value 0xcafebabe would be stored sequentially in memory starting at address 0x100 as follows:

Address: 0x100 0x101 0x102 0x103

Value: be ba fe ca

The least significant byte (LSB) is stored at the lowest memory address (0x100), and the most significant byte (MSB) is stored at the highest memory address (0x103).
