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.

We began this chapter by differentiating between logical and physical topologies before looking at the various topologies. The topologies covered included bus, ring, star, mesh, and hybrid, and we highlighted the benefits and disadvantages of each in terms of performance, resiliency, and cost.

You have learned how to understand the flow of the data using logical topologies and from that to understand some of the areas to troubleshoot on each topology in the event of a failure. On bus topologies, you have also learned about the importance of terminators to avoid signal bounce. In addition, you have learned the two calculations needed to identify the number of interfaces and cables in a full mesh topology, which will assist you greatly in planning such a deployment.

In the next chapter, you will be introduced to the first of the two intermediary network devices this book...
