You are relatively new member of a project team that is developing a retail store management system for a chain of sporting goods stores. Company headquarters is in Las Vegas, and the chain has twenty$-$seven locations throughout Nevada, Utah, and Arizona. Several cities have multiple stores.

$$ The new system will be a networked client$$server architecture.

$$ Stores will be linked to one of three regional servers, and the regional servers will be linked to corporate headquarters in Las Vegas.

$$ The regional servers also link to one another.

$$ Each retail store will be outfitted with similar configurations of two PC$-$based point$-$of$-$sale terminals networked to a local file server.

You have been given the task of developing a network model that will document the geographic structure of this system.

Draw a High level and Low Level network model for this organization.
