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.

Implementing wireless topologies

Wireless networks can fall into general topographic groups, ad hoc and infrastructure. We will discuss both of these in this section, as well as some peripheral information pertinent to wireless networks, such as planning a network.

In Chapter 2, Understanding Local Area Networks, we discussed various areas that we needed to consider when planning our LAN. All of these are still valid in a wireless network, but I would like to specifically highlight some that have a major impact on the performance of a wireless network:

  • Hardware: Recall that in the preceding section, we discussed the different wireless standards, and how they needed to support the same frequency to be compatible.
  • Environment: One of the reasons we would implement a wireless network is to support devices in locations where we do not have the capacity to lay cables. This may cause...
