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.

Scales of networks

Networks can be described in terms of their scale of deployment according to how much of an area they cover or what type of area they cover. The exam objectives specifically call out LANs and wide area networks (WANs). LANs and WANs will be discussed in this and the following chapters. I will round off this chapter with a brief explanation of metropolitan area networks (MANs), campus area networks (CANs), and Personal Area Networks (PANs). The following diagram is a visual representation of where each of these fits in the scale of networks:

It should be noted that you may see the acronyms prefixed with the letter W; for example, WLAN, WWAN, and so on. This usually indicates that it is a wireless variant of the network.
