In a client-server network, some of the ndoes on the network are nominated as clients and some are nominated as servers. Clients request services from servers, such as shared resources or email information, and the server will respond. Arranging a network like this has a few advantages, such as allowing for easier backups and a higher level of security since everything is maintained by a central authority.
