R4.1 Quiz: Algorithms in Digital Analysis

An algorithm is best described as:

• A random set of instructions.

• A step-by-step procedure for solving a problem.

• A piece of software.

• A mathematical equation.

Which of the following is NOT a characteristic of an algorithm?

• Finiteness

• Ambiguity

• Clearly defined inputs

• Logical sequencing

"If the number is even, divide by 2. Otherwise, multiply by 3 and add 1." This statement demonstrates which algorithmic characteristic?

• Iteration

• Selection

• Finiteness

• Unambiguous

Structured English is used in algorithms to:

• Make them more concise.

• Improve readability for humans.

• Make them easier for computers to understand.

• Ensure they are mathematically correct.

What is the purpose of iteration in an algorithm?

• To repeat a set of steps until a condition is met.

• To choose between different paths.

• To define the starting point.

• To ensure the algorithm terminates.

Which of the following is NOT an application of algorithms in digital analysis?

• Automating payroll calculations.

• Designing a video game.

• Writing a poem.

• Training a machine learning model.

"Input: A list of numbers. Output: The largest number in the list." This statement defines:

• The algorithm's logic.

• The algorithm's iteration.

• The algorithm's inputs and outputs.

• The algorithm's selection process.

Why is it important for algorithms to be unambiguous?

• To ensure they can be understood by different people.

• To prevent errors in the calculations.

• To make them more efficient.

• To comply with programming standards.

An algorithm that never ends violates which characteristic?

• Finiteness

• Unambiguous

• Clearly defined inputs

• Logical sequencing

Machine learning algorithms are used to:

• Solve simple mathematical problems.

• Find patterns and make predictions in data.

• Create complex visualisations.

• Write computer programs.
