1.1 Computational Thinking

Question 1

What is modularisation?

Answer 1

Making a system less complicated by breaking it down into individual units (modules)

Question 2

What is top-down problem-solving?

Answer 2

A hierarchical approach where the main objective is identified first, then broken down into goals needed to achieve this and who to assign to each goal

Question 3

What are the advantages of top-down problem-solving? (3)

Answer 3

• The solution, requirements and costs can be explained earlier
• The project can be easier to manage as the goals can be allocated to different teams
• Each sub-goal can be broken down until it’s small enough to be created

Question 4

What is bottom-up problem-solving?

Answer 4

When separate teams are assigned to work on different areas of the project without being told how to do it. This requires more coordination between teams

Question 5

What is decomposition?

Answer 5

Breaking down a complicated task into a set of more easily achievable tasks

Question 6

What is pattern recognition?

Answer 6

Identifying different problems with the same solution

Question 7

Why is pattern recognition important in software development?

Answer 7

Features, such as libraries, can be used in multiple programs to save time when programming, so you don’t have to type the same code over and over
