This publication is created to help beginners who are already familiar with computers to discover the secrets of TCP/IP. It will be useful for students, advanced users, computer and network administrators, computer managers, and security managers. Professionals who want to discover secrets of Internet technology can also appreciate it. It will be also useful as a textbook of TCP/IP lectures.
This publication contains a lot of examples. Please do not blame us if we take the side of some particular operating system; we have put here examples from both Windows and UNIX, and sometimes even CISCO. We have added a supplement containing the basics of the CISCO system because a basic knowledge of the operating system of CISCO routers is essential not only for network administrators, but also for the general readers.
This book explains the TCP/IP concepts to users, independently of the hardware and software they use. Readers can effectively work with TCP/IP even in a not-so-powerful personal computer.
