   A wide area network (WAN) is a computer network that covers a wide geographical area (ie, any network whose communications links cross metropolitan boundaries, regional, or national). Or, less formally, a network that uses routers and public communications links. Contrast with personal area networks (pans), local area networks (LANs), the Campus Area Networks (milk), or metropolitan area networks (crews) that are usually confined to a room, respectively, to a construction at a campus or specific metropolitan area (eg a city). The largest and most well known example of a WAN is the Internet. WANs are used to connect (LANs) and other types of networks together, so that users and computers in one location can communicate with users and computers in other locations. WANs are built for very special organization and is reserved. Others, built by Internet service providers, provide connections from an organization 's LAN to the Internet. WANs are often built using leased lines. At each end of the leased line, a router connects to the LAN on one side and a hub within the WAN on the other. Leased lines can be very expensive. Instead of using leased lines, WANs can also be built using less costly circuit switching or packet switching methods. Network protocols including TCP / IP deliver transport and functions of call. The protocols including packet relays over SONET / SDH, MPLS, air and the screen are often used by the service providers deliver the links that are used in WANs. X. 25 had an important early WAN protocol, and are often regarded as the "grandfather" of the relay of the page as many of the protocols and functions of the bottom of the X. 25 is still in use today (with upgrades) by the relay of the page. The academic research on wide area networks can be divided into three areas: Mathematical models, network emulation and network simulation. Such a network generally requires the intersection of right-of-meaning public and has at least in part on the circuits supplied by a common carrier. Typically, a WAN consists of a number of switching nodes connected. A transmission from any one device is designed with these internal nodes to the destination device specified. These nodes (including boundary nodes) are not affected the content of the data, but rather its purpose is to provide a distribution channel that will move data from node to node until they reach their destination. The performance improvements are sometimes transported by the WAFS or WAN optimization. http://en. wikipedia. ? of org / wiki / Wide_area_nâ |

   not sure that your instructor wants include special but I would go to WWW. Cisco. COM and get spec. on the switch. Addition, the Web site www. HowStuffWorks. COM? a good resource to help you get a sense of understanding of the switches and work of the stuff.
