Unit 7: Data structures

AQA Paper 1



The unit is subdivided into seven topics plus a test. It covers all of Section 4.2 of the AQA A-Level specification 7517. (Arrays, records and files are covered in AS Unit 1.) The unit gives practical and worked examples of each of the different abstract data structures including queues, stacks, lists, graphs, trees, hash tables and dictionaries. The function and practical application of each data type is discussed, with pseudocode and coded program solutions for some algorithms in VB or Python. Vectors and dot products and their application are covered in a final topic before a comprehensive examination-style assessment of the understanding across the whole unit.

What's included?
