Answer:
2 times more unique IDs
Explanation:
The number of bits used to represent unique IDs in the computer system = 10 bits
The number of bits to which the database is upgraded to = 11 bits
The number of unique IDs represented by a 10 bits binary sequence, n = 10¹⁰ = 1024
The number of unique IDs represented by a 10 bits binary sequence, n = 10¹¹ = 2048
Therefore, the number of times more unique IDs that can be represented with the new system of 11 bits = 2048/1024 = 2 times more unique IDs
