Explain Deterministic Computing with the help of an example.

Deterministic computing refers to the computing model where the outcome of a computation is predictable and consistent for a given set of inputs. In deterministic systems, the same input will always produce the same output, regardless of when or how many times the computation is performed. This predictability is essential in applications where reliability and accuracy are critical, such as embedded systems, real-time systems and financial calculations.

Example: Calculating the factorial of a number

Given a non-negative integer n, the factorial n! means the product of all positive integers from 1 to n.

For instance, if n = 5, then 5! = 5 × 4 × 3 × 2 × 1 = 120

No matter how many times we perform this calculation or when we do it, 5! will always yield 120. This demonstrates deterministic computing, since the output is predictable and consistent for any given input.
