SOME OF THE MAIN TOPICS IN THIS CHAPTER ARE

A network administrator must wear many hats because the network is composed of many elements, implemented in both hardware and software. In a large network environment, many tasks are delegated to those who are particularly adept in a specific technology. However, the administrator who sits at the top of the management ladder needs to understand the principles under which the network functions and the tools that are used to keep it in good working order. This chapter discusses the basic tools used to troubleshoot the underlying structure of the network (such as the cabling), as well as those used to pick apart the semantics of the communication process (packets and protocols).
