Exploring Computational Thinking

What is the first step in computational thinking?

• Implement the algorithm

• Define the problem

• Analyze the data

• Identify the solution

Which of the following is a base-2 number system?

• Decimal

• Binary

• Octal

• Hexadecimal

What does an algorithm represent?

• A type of programming language.

• A method for storing information.

• A random collection of data.

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

In a flowchart, what does a diamond shape typically represent?

• An input/output operation.

• A connector between shapes.

• A decision point.

• A process step.

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

• Efficient and effective

• Clearly defined steps

• Simple and straightforward

• Overly complex or convoluted

What is the decimal equivalent of the binary number 1010?

• 11

• 8

• 1011

• 10

In pseudocode, how do you typically start a function definition?

• function functionName with parameters

• functionName(parameters) start

• function functionName(parameters)

• define functionName(parameters)

What is the purpose of using flowcharts in algorithm design?

• To ensure the algorithm runs faster and more efficiently.

• To replace the need for coding the algorithm entirely.

• To create a detailed written report of the algorithm.

• The purpose of using flowcharts in algorithm design is to provide a visual representation of the algorithm's steps and decision points.

Which of the following best describes 'decomposition' in computational thinking?

• Decomposition refers to the analysis of data without breaking it down.

• Decomposition is the process of combining multiple problems into one.

• Decomposition is the method of solving problems by ignoring their complexity.

• Decomposition is the process of breaking down a complex problem into smaller, manageable parts.

What is the main advantage of using pseudocode over programming languages?

• It is a formal programming language with strict syntax rules.

• It provides built-in debugging tools for complex algorithms.

• It allows for direct execution of algorithms without translation.

• It simplifies the representation of algorithms and enhances readability.
