[Year 12 SofDev] Deja vu

[Brett Fitzsimmons]

I think there is a distinct difference between “table” and “function”.

Hash functions have applications other than being used for associative arrays or hash tables (as mentioned in study guide).They are used for encryption algorithms such as MD5. Also, the implementation of an associative array is dependent on the language - it might not even use an array, it could be implemented as a linked list or red-black tree or any data data structure. 

I think this needs to be clarified for next year.
