### Travelling a network

Many practical problems have travel routes which are modelled by networks. This post will explain travelling a network in HSC Standard Math and go through

- Network Travel Terminology
- Identifying the walk
- Traversable and Non-Traversable Graphs

### Network Travel Terminology

The following video introduces the terminology involved in network travel including; walks, trails, paths, circuits.

### Identifying the walk

The following video explains how to identify which type of walk a network undertakes using the appropriate. terminology

### Traversable and Non-Traversable Graphs

A **traversable graph **has a trail that includes every edge. A **non-traversable** **graph **has a trail that does not include every edge. The following video explains the difference between traversable and non-traversable graphs.
