# Network Theory- 2 Overview

In this module we will give an overview to the different questions that we are interested in trying to answer when it comes to analysing networks, this module also works as an overview to the content we will be covering during the rest of the course.​

Transcription: In this section we are going to give an overview to network theory that will also work as an overview to the structure of this course and the content we will be covering. As the name implies network theory is all about the study of networks, we are trying to create models so as to analyze them, in order to be able to do this the first thing we need is some kind of formal language and this formal language is called graph theory. We will be going into the details of graph theory in the next lecture but it is a relatively new area of mathematics that gives us some kind of standardized language with which to talk about and quantify the structure and properties of networks. So once we have this basic vocabulary, say you give me a network to analyze the question then turns to what are the features and properties of this network that we should be really interested. The first set of questions we might like to ask relate to individual elements within the network. We want to know what are the nodes within the network what are the connections between them and what properties are we really interested in, for example in a computer…
