Overview of this book

A network is a collection of computers, servers, mobile devices, or other computing devices connected for sharing data. This book will help you become well versed in basic networking concepts and prepare to pass Microsoft's MTA Networking Fundamentals Exam 98-366. Following Microsoft's official syllabus, the book starts by covering network infrastructures to help you differentiate intranets, internets, and extranets, and learn about network topologies. You’ll then get up to date with common network hardware devices such as routers and switches and the media types used to connect them together. As you advance, the book will take you through different protocols and services and the requirements to follow a standardized approach to networking. You’ll get to grips with the OSI and TCP/IP models as well as IPv4 and IPv6. The book also shows you how to recall IP addresses through name resolution. Finally, you’ll be able to practice everything you’ve learned and take the exam confidently with the help of mock tests. By the end of this networking book, you’ll have developed a strong foundation in the essential networking concepts needed to pass Exam 98-366.

Understanding routing protocols

A lot of people have this notion that routing involves some form of device that takes your data from your internal network and routes it out on to the internet. In part, this is correct, but for me, it is too specific a description and can be slightly misleading. A better definition would be that routing takes data from a network and forwards it through one or more networks to reach a destination network. These networks could be private to private, private to public, private to public to private, and any combination of any number of networks to get to the final destination.

In this subsection, I will briefly describe routing devices, and then talk about the common routing protocols available to us.
