Network architecture

What is it? what does it do?

Network architecture refers to the design and structure of a computer network — it includes hardware components, software components, protocols, and communication technologies. Both small local area networks (LAN) and sizable wide area networks (WAN) rely on network architecture to organize infrastructure securely. A good architecture defines how the elements of a network are organized and how they interact with each other to enable data communication and resource sharing.
