Networking: A Beginner's Guide
Hertz and bits per second are essentially the same and are sometimes intermixed.
For example, thin Ethernet cable is said to run at 10 MHz and also to carry 10 Mbps of
bandwidth.
Chapter Summary
This book would double in size if I tried to explain every networking term every
time it was used. To keep it at a reasonable length (and readable), I assume that you
understand the basic concepts presented in this chapter, as well as the information
found in the glossary near the end of the book. Most people leave glossaries unread
until they come across a term they don't know. In this case, I recommend that you
spend a few minutes reviewing this book's glossary before you read the following
chapters, to make sure that you are familiar with the terms that are used. Node, host,
broadband, baseband, workstation, client, and server are some examples of terms that the
rest of the book assumes that you understand. The glossary defines these terms and
many others.
In the next chapter, you learn about the basic types of networks, as well as an
important conceptual model of networking that you will frequently encounter when
working with networks: the Open Systems Interconnection (OSI) model. The OSI
model is used in virtually every aspect of networking, and it provides a framework for
how networks operate.
