There are few inputs, but a lot of outputs. 2 outputs come from the same input

Answer 1

A collision in a hash function occurs when 2 inputs map to the same output. This means that two different pieces of data (inputs) produce the same hash value (output), which is undesirable as it undermines the uniqueness property of the hash function.
