Thread: What is a wide area network Network

A Advanced Breadth Arrangement is a communicating arrangement created of PCs that are non-local to some other, substituting advice throughout a advanced breadth or accomplished distance. The best basal archetype is the Internet, admitting a WAN crave not be all-around to authorize as a advanced breadth network. Since computer acronyms accept about-face basal words, the analogue “WAN network” is generally activated in the accessible part, still admitting redundant. For those beginning to these acronyms, including the chat “network” can be a admonition of what a WAN is, so while this commodity utilizes the basal term, the actual appellation is WAN, arresting agnate functioned with a “W.”

Like a freeway arrangement in a ample metropolis, if one freeway or advice artery is taken out, abstracts cartage is automatically re-routed about the breakdown through alternating routes.


Some examples of abate networks in the WAN accommodate Municipal Breadth Networks (MANs), Campus Breadth Networks (CANs) and Local Breadth Networks (LANs). MANs accommodate connectivity throughout a burghal or bounded breadth for accessible admission to the Internet, while CANs action connectivity to acceptance and adroitness for on-site assets and online access. LANs can be either clandestine or public, but are usually clandestine networks with alternative online access. The home or appointment arrangement is a acceptable archetype of a LAN.


A LAN can additionally become a WAN if, for example, a aggregation with address in both Los Angeles and Chicago links their two LANs calm over the Internet.
