Question

A computer database uses a binary sequence of 4 bits to represent unique user IDs. To increase the number of unique IDs that the database is able to represent, the database administrator increases the number of bits in a user ID to 7 bits. How many times more unique user IDs can be represented with the new system?

Answer 1

The answer is "A device may include
`2 ^(56)`time more unique user IDs".

Step-by-step explanation:

In the given question the total user ID access availability of 5 bits would also be
`2^(10)`, and for user ID listings, its 12 bits should generate a maximum
`2^(66)` data allocation.

In this, it first calculate the value that is
`2^((66-10))=2^(56)` times, which was its amount of times most specific user IDs, that's why
`2 ^(56)` time is correct answer.
