Week 2: Moving data: an introduction to switching and routing

Introduction

In this second week of the course you will work through the third and fourth sessions of the course.

The third session introduces you to how data is moved across a local area network. It introduces you to two devices that make this happen – switches and routers – and finally looks in more detail at the work of switches to deliver data within a network

The fourth session extends what you have learnt in session three to look at routers and how they deliver data across networks.

Both sessions are taught by Helen Donelan, a Senior Lecturer at the Open University.
