[Year 12 SofDev] VCAA sample questions and examiniation advice revisited

[Matheson, Heath A]

Heya all,

 

Some of my students are going through the sample questions posted back
in April 07 on the SD VCAA website.  I looked back at the archives (Apr
07) and found Mark and Gordon's multi choice answers which I agreed with
but I'm trying to work out what is expected from Question 2 of section
B. 

 

It states:  Three simple types of data structure are arrays, records and
linked lists.

For each of these three data structures, identify the types of data that
they deal with and the way the data is organised. (6 marks)

 

Is "types of data" different from "data types"? 

 

My thoughts are linked lists are sequential and ordered while arrays can
have random access, is this organisation?

An array can only hold one data type while a record can have several
different data types.

 

I would love some help on this one. 

Three sleeps til I can clear the mess of exam papers off my desk!

Cheers!
