Question 1

What does thinking ahead help with?

Answer 1

-Maximising code efficiency
-Minimise errors

Question 2

What are preconditions?

Answer 2

Conditions that already exist and could effect how you devise the solution to a problem

Question 3

Why are preconditions important to devising a solution to a problem?

Answer 3

If all preconditions aren’t meant then the finished product will not work correctly

Question 4

What does caching allow?

Answer 4

Faster retrieval times as instructions and data don’t need to be fetched from secondary storage instead (which is much slower)

Caching algorithms are difficult to implement

Question 5

What is prefetching?

Answer 5

A more effective version of caching, but requires clever algorithms to make predictions that data will need to be retrieved soon

Question 6

Why should program code be reused?

Answer 6

To save coding time, save resources, lower development costs and reduce the amount of redundant code

Basically libraries
