This book has been completely updated for its fourth edition. Chapters relating to network operating systems such as Novell NetWare 6.5, Red Hat Linux, and Windows Server 2003 have been added to get you up to date on the latest network operating systems. Since TCP/IP is the standard network protocol, a new chapter on TCP/IP administration (Chapter 13) has been added to help you get up and running with the aspects of using and administering TCP/IP on a network.
The book is divided into four parts ; each part provides you a body of information that covers a particular area related to computer networking. Part I, "Networking Basics," provides an overview of computer networking and information on network hardware. It also covers the basics of peer-to-peer and server-based networks. It includes information on networking hardware and also provides you with information on the different protocol stacks that are used on networked computers. The different media for building the network infrastructure, such as Ethernet and IBM Token-Ring, are also discussed.
Part II, "Getting the Network Up and Running," covers the configuration aspect of peer-to-peer networks and also provides an overview of working with network operating systems. Chapters providing an overview of the network operating systems Novell NetWare, Red Hat Linux, and Microsoft Windows Server 2003 are also included.
Part III, "Expanding Your Network," discusses how to administer a TCP/IP network, which includes information on using DNS, DHCP, and subnetting an IP network. Information on how to use WAN technology to expand and connect LANs at different locations is also included. This part of the book also discusses how to connect a network to the Internet and develop a company Web site.
Part IV, "Keeping the Network Running Smoothly," discusses how to protect network data using strategies such as RAID arrays and backups and also discusses how to troubleshoot network problems. This part of the book provides a primer on network security, which includes information on protecting the network from viruses and outside attacks. New chapters related to disaster planning and serving as a network administrator have also been added.
To help you keep track of all the new terminology that is introduced in the book, Appendix A provides a glossary. This will allow you to review the new terms that are introduced in the various chapters of the book.
Exploring computer networking and the various hardware and software components required is certainly an exciting endeavor. I hope that you enjoy this book as much as I enjoyed writing it.
