Chapter 4. How to Build a Local (Network) Roadway

What You Will Learn

After reading this chapter, you should be able to

  • Explain how computers can communicate binary 1s and 0s using electricity

  • List the components of popular LAN cables and connectors

  • Compare and contrast straight-through and cross-over Ethernet cables

  • Explain the operation of an Ethernet hub

  • Summarize the benefits of using a structured cabling system

So far in this book, you have read about how networks allow computers to communicate. Networks include software, some of which sits in the computers, and some of which sits in routers. The network also includes hardware, such as the network interface cards (NICs) in the PCs, mentioned in Chapter 3, "Building a Network: It All Starts with a Plan." Finally, networks include cabling, which provide a physical means to transmit bits across a network.

This chapter is the first one in this book's second major part: "Running the Local Department of (Network) Transportation." In the United States, most cities, all states, and the U.S. federal government have a department of transportation (DOT). Each DOT plans, builds, and fixes problems with roadways. You can learn a lot about networking by comparing networks to roads.
