|  |  | Overview
Now that you a firm understanding of data flow through the OSI model, along with Layer 1 and 2 concepts and technologies, you are ready to start learning how to design networks. Network design takes many technologies into consideration (e.g. token-ring, FDDI, and Ethernet). For example, a Layer 1 LAN topology must be developed, and the type of cable, and the physical (wiring) topology must be determined. In this chapter, you will learn how the network design's physical and logical topologies should be designed and documented, as well as any brainstormed ideas, problem-solving matrices, and any other notes you made while making your determinations. You will also learn about wiring closet specifications used in LANs. In addition, you will learn about wiring and electrical techniques used in building networks.
Note: In this chapter, you may need to convert units of measurements. A small utility to help you make the conversions is available here. You can access it from anywhere in this chapter via the Index button below.
