Wide Area Networks The creation of wide area networks links mass communication from people all over the world with a vast variety of different uses. “A wide area network is telecommunications networks covering a large geographic area.” The internet is the biggest example of a wide area network and has influenced our daily lives all around the world. Wide area networks are connected to local area networks to enable computers to share, send, and access information on a larger scale. These recent technologies over the past 20 years have affected the way we communicate, how businesses operate, and many other factors that we take for granted. Wide area networks are a fast growing telecommunications business which are developing new…show more content…
These five types of connections are Point-to-Point Links, Circuit Switching, Packet Switching, WAN Virtual Circuits, and WAN Dialup Services. “Point-to-point links provide a single, pre-established WAN communications path from the customer premises through a carrier network, such as a telephone company, to a remote network.” The lines are designated for this connection and usually run on leased lines but are typically more expensive than a service which is shared. Circuit switching enables data connections when the user goes to access another network. Like a telephone line the connection is linked by a router and when this information is allowed by circuit switches the router accesses the data transmits a connection. This connection actually makes a call and connects similar to a phone call. Once the information is translated and sent the user cancels the connection when they are finished. “Packet switching is a WAN technology in which users share common carrier resources.” Packet switching has carrier networks that allow people with this feature to share from this network. These carrier networks hold packets of information that can be accessed by many customers at any time. WAN virtual clients work with a virtual circuit which is a logical circuit created within a shared network between two
