Homework - 53. OCR GCSE (J277) 2.1 Structure diagrams

What does decomposition mean in the context of problem-solving?

• Combining multiple problems into one

• Breaking a problem down into smaller, more manageable parts

• Ignoring the problem

• Solving the problem in one step

What is a common tool used when decomposing a problem?

• Flowchart

• Structure diagram

• Mind map

• Gantt chart

What approach is used to create structure diagrams?

• Top-down analysis

• Step-wise refinement

• Bottom-up synthesis

• Lateral thinking

In the example provided, what is the overall program designed to handle?

• Employee recruitment

• Handling wages for a company

• Inventory management

• Customer service

Which of the following is NOT one of the main tasks identified in the example program?

• Inputting all the employees' details

• Calculating their pay

• Producing their payslips

• Managing employee holidays

What might the 'calculate pay' task be broken down into?

• Calculate net pay and calculate bonuses

• Calculate gross pay and calculate total deductions

• Calculate overtime and calculate expenses

• Calculate hours worked and calculate salary

Which of the following is NOT a sub-task under 'calculate deductions'?

• Calculate income tax

• Calculate national insurance

• Calculate non-paid sick days

• Calculate overtime pay

What should every lowest-level node on a structure diagram achieve?

• Multiple tasks

• A single task

• No tasks

• A complex task

What is the purpose of using structure diagrams in problem-solving?

• To make the problem more complex

• To illustrate problem decomposition

• To avoid coding

• To create a visual representation of the solution

What is the benefit of breaking down a problem into smaller components?

• It makes the problem harder to solve

• It allows for easier coding and understanding

• It increases the number of errors

• It reduces the need for analysis
