Client/Server architecture is a network architecture in which each computer or process on the network is either a client or a server. Clients are devices or applications that request services or resources from the servers. Servers are devices or applications that provide services or resources to clients.
This architecture is not restricted to a specific type of network and can be implemented in various networking environments, including local area networks (LANs), metropolitan area networks (MANs), and wide area networks (WANs). The choice of architecture depends on the scale and requirements of the network.
