Sams Teach Yourself TCP/IP Network Administration in 21 Days is a straightforward professional tutorial on the popular, but poorly documented protocol suite, TCP/IP. It teaches the reader how to set-up and maintain their network using the suite of TCP/IP protocols. From the basics about open systems, standards and protocols, SLIP and PPP, and security, to the ins and outs of using TCP & IP, this book will teach the reader creatively--using quizzes, Q&A, and workshop sections. Like Teach Yourself TCP/IP in 24 Hours, Teach Yourself TCP/IP Network Administration in 21 Days, 3E will cover all the topics a reader will need in order to implement TCP/IP onto their network. However, the 21 days book will go into more depth for each topic, taking the time (and pages) to explain and explore the nuances of this far-reaching suite of protocols more thoroughly for the network administrator.
