What device is designed to generate a sequence of numbers that lack any pattern?

• A. Random Number Generator (RNG)
• B. Pseudo Random Generator
• C. Entropy Source
• D. Pattern Engine

Answer: (A)

To get a sequence with no detectable pattern, you need randomness. A Random Number Generator is designed to produce numbers that appear truly random and without obvious patterns. Hardware RNGs use unpredictable physical processes (an entropy source) to generate random bits, while software pseudo-random generators rely on a deterministic algorithm and a seed; they can become predictable if the seed is known or repeated. An entropy source alone provides randomness as input but isn’t a full sequence-generating device. A pattern engine suggests creating patterns, which is the opposite of randomness. So, the device that best fits the goal of generating numbers with no pattern is a Random Number Generator.
