Graphs

A graph is a collection of two sets: vertices and edges. Two adjacent vertices or nodes are connected by edges or arcs. A graph is classified as a non-linear data structure.  

There are two types of graphs:

  1. Directed graphs: In directed graphs, all the edges are unidirectional.
  2. Undirected graphs: In undirected graphs, all the edges are bidirectional.

This A Level Computer Science module introduces graphs to your students, explaining:

  • Graphs and its types
  • Implementing graphs in programming
  • Traversing graphs
