    Answer: 2 ^56 times more unique user ID's can be represented in the system.

    Explanation:

    5 bits will produce a maximum data allocation for User ID entries of 2^ 10.

    12 bits will produce a maximum data allocation for User ID entries of 2^ 66.

    Therefore the number of times more unique user ID's will be represented is 2^ (66-10) = 2 ^ 56 times.
