What is the first step in computational thinking (not shown in the diagram)

• Pattern recognition

• Decomposition

• Computational thinking skills

• Representation of problem elements

What is the first step in decomposing a process according to the diagram in the image?

• Calculate net pay per month from annual salary

• Get annual salary

• Calculate deductions

• Subtract all deductions from gross pay per month

Which of the following is NOT listed as a key step in pattern recognition?

• Examining problems to identify the inputs, processes (including selections and iterations) and outputs that are present.

• Making predictions based on identified patterns.

• Describing problems and processes as a set of structured steps.

• Highlighting elements that are unique to each process.

According to the text, what essential skill must a programmer have when communicating problems to others?

• Ability to use business-specific language

• Ability to solve problems quickly

• Ability to adjust delivery to meet different audience needs

• Ability to recognize patterns instantly

What is the final step in calculating net pay per month as shown in the diagram?

• Calculate taxable pay

• Calculate deductions

• Subtract all deductions from gross pay per month

• Divide annual salary by 12 months

What is the concept of abstraction in computing as described in the text?

• A method to increase the complexity of systems

• A process where systems are divided into multiple layers to hide the underlying complexity

• A technique to physically remove system components

• A strategy to enhance user interface designs

According to the text, what is the purpose of identifying the information required to solve an identified problem in computational thinking?

• To determine the least important information

• To understand the rationale and format needed for the information

• To simplify the problem to its most basic elements

• To increase the complexity of the problem

What are 'constants' as defined in the text?

• Values in a problem that change frequently

• Processes that are critical to understanding a system

• Values in a problem that do not change over a reasonable period

• Information presented to the user in a required format

Which of the following best describes 'variables' in the context of computational problems?

• The processes that occur multiple times within a problem

• The values in a problem that may change, typically input by the user

• The outputs that are generated as a result of system processes

• The constants that remain fixed throughout the problem

What is meant by 'repeated processes' in system representation?

• Processes that change each time they are executed

• Values that remain constant in the system

• Processes that occur multiple times within a problem

• Variables that are typically input by the user
