Algorithms, Decomposition & Abstraction Quiz

What is computational thinking?

• Solving problems that can be implemented by a computer system

• Writing code in a specific programming language

• Designing computer hardware

• Creating graphical user interfaces

Which of the following is NOT a principle of computational thinking?

• Compilation

• Algorithmic thinking

• Decomposition

• Abstraction

What is an algorithm?

• A set of step-by-step instructions to solve a problem

• A type of computer hardware

• A programming language

• A software application

What is decomposition in computational thinking?

• Writing code in a modular way

• Breaking down a large problem into smaller problems

• Removing unnecessary details from a problem

• Combining multiple solutions into one

Which of the following is a benefit of decomposition?

• It makes the problem unsolvable

• It increases the complexity of the problem

• It requires more resources

• Smaller problems are easier to solve

What is abstraction in computational thinking?

• Removing unnecessary details to focus on important features

• Breaking down a problem into smaller parts

• Writing code in a specific programming language

• Combining multiple algorithms

Which of the following is an example of abstraction?

• Breaking down a problem into smaller parts

• A map of a bus or train route

• Writing a detailed report

• Combining multiple solutions

In a computer game, what is an example of decomposition?

• Focusing only on the main character

• Ignoring the visual aspects

• Writing the entire game at once

• Designing levels independently

What is the purpose of using abstraction in computer games?

• To focus only on the main character

• To remove all visual elements

• To increase the complexity of the game

• To make the game realistic and visually appealing

Which of the following is NOT an example of abstraction?

• Developing a car or flight simulator

• Simulating a sport in a computer game

• Creating a map of a train route

• Including the time a try was scored in a rugby match program
