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 Local Area Networks

Most network engineers will cut their teeth supporting an organization's internal network infrastructure. This internal infrastructure will normally take the form of a local area network (LAN). Therefore, it is important to have a good understanding of LAN technologies to provide this support and ensure that the organization can continue to function effectively and efficiently. Any network failures can have results ranging from inconvenience to financial loss.

This chapter focuses on the implementation of LANs in a small office/home office environment. We will discuss the differences between a LAN and a WAN, as well as the use of private IP address ranges. We will identify the key components in both wired and wireless networks, and finish by discussing virtual local area networks (VLANs).

The following topics will be covered in this chapter...
