Which of the following is not one of the four pillars of computational thinking?

• Abstraction

• Data mining

• Decomposition

What does a top-down approach in problem-solving involve?

• Identifying a list of small tasks and assembling them into a larger task.

• Looking at the problem as a whole and then breaking it down into smaller problems.

• Starting with the smallest part of the problem and working upwards.

• Ignoring the main problem and focusing only on the details.

In programming, what does identifying the problem mean?

• Writing the code

• Debugging the program

• Getting used to the problem domain

• Testing the program

Which of the following best describes a bottom-up approach in problem-solving?

• Starting with a general idea and then finding specific examples.

• Breaking the problem into smaller parts without a predefined strategy.

• Identifying small tasks you know about and assembling them into a larger task.

• Solving the problem from start to finish in a linear fashion.

What is a module in the context of computer programming?

• A collection of related functions and procedures.

• A type of computer hardware.

• A programming language.

• A network protocol.

Which of the following best describes the purpose of modularising code?

• To increase the complexity of the code.

• To make the code easier to manage and understand.

• To reduce the speed of execution.

• To increase dependency between different parts of the code.

How can one module utilise the functions of another module?

• By disconnecting from the main program.

• By overriding all existing functions.

• By using the functions of another module.

• By deleting unnecessary functions.
