Unlike the vast array of networking
books written by geeks for geeks, this book was written for you and for anyone who
wants to understand the computer networking phenomenon that has taken the world by
storm. (In other words, it’s by geeks for nongeeks.) We understand that the vast majority of
people working in this industry are not networking experts and that it is difficult to understand
complex technical and business issues before knowing the answers to such questions
as “How does the web work?,” “What is a router?,” and “What is an IP address?”
Whether you are a home computer user who has just purchased a broadband Internet connection
or a company executive who wants to understand what your IT staff is talking
about, this book is for you.
If you’ve decided that you want to make a career change, or if you are in school pursuing a
Cisco certification, we believe that this book will serve both as a good primer, introducing
the concepts of networking in clear and simple terms, and as a useful reference book as you
grow in your career.
We are pleased with the reception the book has received since it was first published. We
have received a great deal of positive feedback both from our intended audience and, much
to our surprise, from very technical people as well. In fact, the book has had enough interest
that we were approached to write a second edition to cover all the new technologies that
have come about in the last five years. After all was said and done, about half of this book
ended up being new.
Among the biggest additions to this version are the topics covering security, communication
tools, and wireless technologies. Security has become one of the biggest areas of investment
for networking as companies attempt to protect their network and data from ever-increasing
threats and attacks. Communication tools have also changed quite a bit in five years, as
both voice and video tools have become more integrated and more sophisticated. Finally,
wireless is everywhere now, and users expect all the networking tools on the wired network
to be on the wireless network as well.
Another change in this book is that Neil Anderson has joined the writing team. Neil is the
coauthor of four other Networking Simplified books that we have written since the original
release of Cisco Networking Simplified. Neil is a great addition to the team and brings a
wealth of expertise and insight to this edition.
