In this, the first of four parts, we will go over the basics of networking This is one of the few sections in the book where we will not be focusing solely on Cisco gear This information is important, however, because to understand the advanced topics we will be exploring, you must have a solid grasp of the basic principles Included in this part of the book is a section on network models, a section on LAN technologies, and a section on WAN technologies This information will be invaluable later in the book when we look at how Cisco devices use these principles In addition, these sections will help you understand all network environments, not just those dominated by Cisco devices That being said, I invite you to sit back, relax, and breathe in the technology behind networking

The OSI (Open Systems Interconnection) model is a bit of an enigma Originally designed to allow vendor-independent protocols and to eliminate monolithic protocol suites, the OSI model is actually rarely used for these purposes today However, it still has one very important use: it is one of the best tools available today to describe and catalog the complex series of interactions that occur in networking Because most of the protocol suites in use now (such as TCP/IP) were designed using a different model, many of the protocols in these suites don't match exactly to the OSI model, which causes a great deal of confusion For instance, some books claim that Routing Information Protocol (RIP) resides at the network layer, while others claim it resides at the application layer The truth is, it doesn't lie solely in either layer The

protocol, like many others, has functions in both layers The bottom line is, look at the OSI model for what it is: a tool to teach and describe how network operations take place For this book, the main purpose of knowing the OSI model is so that you can understand which functions occur in a given device simply by being told in which layer the device resides For instance, if I tell you that physical (Media Access Control-MAC) addressing takes place at layer 2 and logical (IP) addressing takes place at layer 3, then you will instantly recognize that an Ethernet switch responsible for filtering MAC (physical) addresses is primarily a layer 2 device In addition, if I were to tell you that a router performs path determination at layer 3, then you already have a good idea of what a router does This is why we will spend some time on the OSI model here This is also why you should continue to read this chapter, even if you feel you know the OSI model You will need to fully understand it for the upcoming topics

The terms packet, datagram, frame, message, and segment all have essentially the same meaning-they just exist at different layers of the OSI model You can think of a packet as a piece of mail To send a piece of snail mail, you need a number of components (see Figure 1-1):

Figure 1-1: Snail mail components
Payload This component is the letter you are sending, say, a picture of your newborn son for Uncle Joe Source address This component is the return address on a standard piece of mail This indicates that the message came from you, just in case there is a problem delivering the letter Destination address This component is the address for Uncle Joe, so that the letter can be delivered to the correct party A verification system This component is the stamp It verifies that you have gone through all of the proper channels and the letter is valid according to United States Postal Service standards
A packet is really no different Let's use an e-mail message as an example-see Figure 1-2 The same information (plus a few other pieces, which we will cover later in the chapter) is required:
