Exam-style question
Try this first
A computer scientist is modelling a real-world object for a particular problem. Discuss why including every available detail may be inappropriate, and explain how the chosen model can be put into action to solve the problem.
Model answer
What a good answer should say
- Including every available detail may make the model unnecessarily complex and may include information that is irrelevant to the problem.
- The computer scientist should decide what to include and what to discard, retaining the minimum amount of detail needed to solve the problem to the required degree of accuracy.
- The resulting abstraction can be represented in data structures.
- Algorithms can then be created to perform actions on the modelled data, implemented as program code, and executed.
Explanation
Why this works
The answer should link model quality to the purpose and required accuracy. It should also describe automation as the complete process of creating algorithms, implementing code and data structures, and executing the code.
