As Java programmers, we live our lives on the network. It seems that everything we do involves servers, sockets, protocols, URLs, and the dozens of networking concepts and tools that make up our programming environment. In this chapter, we will attempt to provide an overview of the technology that provides the underpinnings of the network products and APIs that we use every day. The goal of this approach is to help the reader see the dozens of technologies in the Java-programming world as parts of a whole, with a little history sprinkled in.
