Network Architecture is the complete framework of an organization's computer network. The diagram of the network architecture provides a full picture of the established network with detailed view of all the resources accessible. It includes hardware components used for communication, cabling and device types, network layout and topologies, physical and wireless connections, implemented areas and future plans.

This architecture is always designed by a network manager/administrator with coordination of network engineers and other design engineers.
Network Architecture provides the detail overview of a network. It is used to classify all the network layers step-by-step in logical form by describing each step in detail. It is also based on the complete working definitions of the protocols. The architecture is emphaiszed in a distributed computing environment and its complexity can not be understood without a framework. Therefore there is a need to develop applications or methods to layout an overview of a network.
