Summary
In this chapter-1,
 You learned about the items that can be found on a typical network. 
You first learned what a network is and the various elements that make up a network, such as servers, workstations, and hosts.
Then you learned about the different ways of laying out a network.
 You learned about bus, star, ring, mesh, and hybrid topologies.
 You also learned about the different types of physical media in use on networks today, including coaxial, twisted-pair, and fiber-optic media. Finally,
 you learned about some common network devices—including NICs, hubs, switches, bridges, routers, and gateways—seen on a typical network.
