Networking Fundamentals

By: Gordon Davies

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.

Routers and Routing - Beyond a Single Network

In this age of inter-connectivity and global communication, we must start to look at communicating between networks rather than just between devices on the same subnet. One key component of this communication is the router. This ubiquitous network device allows for efficient communication between networks, whether these are networks internal to our organization or remote networks on the other side of the world. After switches, this is arguably one of the most important network devices for a network engineer to understand.

This chapter introduces the concept of routing and provides you with an explanation of how routing decisions are made. Various routing protocols are explained and the characteristics of each provided. Also, we will introduce you to the concepts of Network Address Translation (NAT) and Quality of Service (QoS).
