Which of the following is true about PRNGs?
A) they are not completely random
B) their state is measured in bytes
C) the shorter the state, the longer the period
D) they can never produce the same value

Question

Quizplus · Accepted Answer

PRNGs (Pseudo-Random Number Generators) are algorithms that generate a sequence of numbers that appear to be random but are actually deterministic and not truly random. Therefore, they are not completely random.

Answer: B 
 PRNGs have an internal state which is used to generate the next number in the sequence. The state is typically measured in bytes, and the larger the state, the better the quality of the generated numbers.

Answer: C 
 The period of a PRNG is the number of values that the generator can produce before repeating itself. The shorter the state of the PRNG, the faster it will repeat itself, resulting in a shorter period.

Answer: None of the above 
 Option D which states that PRNGs can never produce the same value is incorrect. PRNGs can sometimes produce the same value due to a phenomenon called collision.
