In this chapter, we expand the discussion to give you a clear understanding of the role of TCP/IP and Ethernet in the operation of networks, from the moment a message is created at a sending node to the time it is processed at the receiving node. At the end of the chapter, we also introduce alternative protocols and packet-moving methods that are used in some circumstances. This chapter will add richness and color to the overall picture of how your e-mail and Web surfing and instant messaging (IM) retrieves your Web pages successfully most of the time and gets your messages to the right place.
