    The 'endianness' of a computer system refers to:

    a)
    The number of bits in the processor's registers.
    b)
    The order in which bytes of a multi-byte word are stored in memory.
    c)
    The maximum amount of RAM the system can address.
    d)
    The CPU's clock speed.

    Explanation

    Big-endian stores the most significant byte at the lowest memory address. Little-endian (used by x86 processors) stores the least significant byte at the lowest memory address. This becomes important when transferring data between systems with different endianness.
