Define the structure and function of MAC addresses.Describe the fields of an Ethernet frame.Describe the types of Ethernet LAN connection media.These abilities include meeting these objectives: You will also be able to describe common Ethernet technologies typically found within these important areas of the overall network. Upon completing this chapter, you will be able to describe LAN networks. MAC addresses and their function are also elaborated on.
Ethernet frame structure is introduced, and important fields are described. This chapter also describes different Ethernet media options (copper and fiber), which are presented together with a description of the most common connectors and cable types. This chapter will ensure that you are comfortable describing these important network structures. LANs have rapidly evolved into support systems that are critical to communications within an organization. LANs allow multiple users in a relatively small geographic area to exchange files and messages and to access shared resources such as file servers. LANs are a relatively low-cost means of sharing expensive resources. These collections of high-speed network equipment allow us to achieve remarkable speeds in accessing network data and information. Local-area networks (LAN) tend to spoil us as network users.
