The byte-ordering scheme used by computers to store large integers in memory with the high-order byte at the lowest address is called:

a. big endian

b. byte-major

c. little endian

d. byte-minor

a. big endian

Explanation:

Endianness determines the order of how the multiple bytes of information are stored in the memory. Big-endian is a byte ordering scheme in which the most significant byte also called the big end of data is stored at the the lowest address. First byte is the biggest so Big-endian order puts most significant byte first and least significant byte in the last. For example: A hexadecimal number 1D23 required two bytes to be represented so in big endian order this hexadecimal number will be represented as 1D 23.
