ABSTRACT
If you have any experience in the world of networking, much of what is covered in this chapter may be familiar to you. This chapter addresses the basics of a network: the parts that plug in together to make sure that information gets from point A to some other point B. If you are an experienced network administrator, the value of this chapter may not be so much the explanation of a hub, switch, and router, but rather the discussion that surrounds the terms and the impact your network choices will have in the overall security of your network.
