that the resources that the users need are located on the local land for example if someone needs to open a file here in New York City you don’t want them to have to go clear down here transverse the white area network to Houston open up a file and bring it back here and work on it over here in New York City then when you say you have to go clear across the country again just to save on a server located down here instead you locate the information and resources that each local area network needs your locally so you could set up a server here in New York City with the information that the users here in new york city would need likewise you would want to store user accounts over here in Portland so that someone who needs to log into the network down here in Houston has to go across the land link clear over here to Portland just to authenticate the the benefit of the wind is that if the situation arises say user here needs access to document that’s being worked upon by a product team over here in Portland they can use the wide area network to get that information and open it over here those are the two different classifications for categorizing networks by their size and their geographic proximity
