final exam paper 3 Q6a (all 5)

Hi, as I understand the principle of referential locality it means that memory references are typically close together. The question asks "With reference to two distinct examples, explain The Principle of Referential Locality, and explain how an operating system kernel may use it to improve performance" What kind of examples is this question after?

With this type of question, you would define and explain the Principle of Referential Locality, then create two scenarios (or examples) that demonstrate how it works and how the OS can use it to improve performance. Ultimately the question is testing your understanding of Referential Locality and seeing if you can apply what you know to a given situation.

Would this be with using the memory management tools like malloc to create arrays in heap instead of stack and caching variables that get used repeatedly?

Not completely sure what you mean but you don't need to provide code for this question. Recall there are two types caching methods you can use that apply the principle of Locality of Reference and you can use two examples to demonstrate how they can be used to speed up code.

You can give examples of code locality and data locality (e.g., in arrays)
