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.

Hybrid topology

One of the definitions of a hybrid is something consisting of mixed components, and that definition fits our purposes here. A hybrid topology is a network topology that connects two or more different network topologies together. Two such examples are a star-bus (Figure 5.12) and a star-ring (Figure 5.13):

Figure 5.12: Star-bus hybrid topology

Looking at Figure 5.13, we can see the bus topology acting almost as a backbone for connecting the two star topologies. Any communications between the two star topology networks will have to abide by the rules of the bus topology, that is, follow the CSMA/CD process for access:

Figure 5.13: Star-ring hybrid topology

As you can see in Figure 5.13, the star-ring hybrid topology involves connecting a number of star topologies over a ring topology. Again, the rules of the intermediary topology need to be followed.
