A network protocol defines rules and conventions for communication between network devices. Network protocols include mechanisms for devices to identify and make connections with each other, as well as formatting rules that specify how data is packaged into messages sent and received. Networking and the OSI Model In this chapter, we begin our journey toward the CCNA certification by examining some networking concepts key to working with Cisco routers. The most important concept is a discussion of the OSI model and how data flows across a network. Once the OSI model is under-stood, it will be easier to design, use, and, especially, troubleshoot Cisco networks. Introduction

    Network Interface: A network interface can refer to any kind of software interface to networking hardware. For instance, if you have two network cards in your computer, you can control and configure each network interface associated with them individually. Some routing protocols allow network administrators to assign arbitrary costs to each network link. In this case, path length is the sum of the costs associated with each link traversed. Other routing protocols define . hop count, a metric that specifies the number of passes through internetworking products, such as routers, that a packet must pass through in a route from a source to a
