The network architecture is the overall design of a network, including the types of devices used, the layout of the network, and the protocols used for communication.

It refers to the specific design or pattern of how nodes (e.g. computers, servers, routers) and links (e.g. cables, wireless signals) are arranged in a network. It determines how data is transmitted, processed and stored within the network. Examples of network architectures include client-server, peer-to-peer, and distributed networks.
