This text is the second edition and presents updated networks material. The word “design” on the title of this book implies the purchasing and installation of the essential hardware and software that one must collect to assemble an effective computer network. Basically, it means the
building of a network. The word “management” is used to denote the duties and responsibilities of
a network administrator. Of course, one may argue that network management should include the Simple Network Management Protocol (SNMP) and Remote Monitoring (RMON). While this is
true, a detailed treatment of those two topics are beyond the scope of this book. Chapters 8 and 9 are introductions to those two topics. SNMP and RMON are discussed in books that are devoted just to these topics.
