Computational Thinking quiz

What is the primary nature of abstraction in computer science?

• Focusing on every detail.

• Simplifying complex systems by focusing on essential features.

• Ignoring all real-world applications.

• Creating overly complex models.

Why is abstraction necessary in computer science?

• To make problems more complicated.

• To manage complexity and focus on relevant aspects.

• To avoid problem-solving.

• To create unrealistic solutions.

How does an abstraction differ from reality?

• An abstraction is more detailed than reality.

• An abstraction omits unnecessary details from reality.

• They are identical.

• Abstractions are always physical objects.

When creating an abstract model of a bus timetable, what would be an essential feature to include?

• The colour of the bus seats.

• The scheduled arrival and departure times.

• The driver's favourite radio station.

• The number of bolts on the bus wheels.

What is the first step in thinking ahead when solving a problem?

• Writing the code.

• Identifying the inputs and outputs.

• Testing the solution.

• Ignoring potential errors.

What are preconditions when devising a solution?

• The final results.

• The initial conditions that must be met.

• Irrelevant factors.

• The program's output only.

What is a benefit of caching?

• Increased processing time.

• Faster access to frequently used data.

• Reduced memory usage.

• Elimination of data storage.

Why are reusable program components important?

• To increase development time.

• To reduce code duplication and improve efficiency.

• To make code harder to understand.

• To create more bugs.

What is the first step in thinking procedurally?

• Implementing the code.

• Identifying the components of a problem.

• Testing the solution.

• Ignoring the problem structure.

What is involved in identifying the components of a solution?

• Only focusing on the output.

• Breaking down the solution into smaller, manageable steps.

• Avoiding any planning.

• Creating the most complex solution possible.
