client-server
     
         A common form of {distributed system} in which
        software is split between {server} tasks and {client} tasks.
        A client sends requests to a server, according to some
        {protocol}, asking for information or action, and the server
        responds.
     
        This is analogous to a customer (client) who sends an order
        (request) on an order form to a supplier (server) who
        despatches the goods and an invoice (response).  The order
        form and invoice are part of the "protocol" used to
        communicate in this case.
     
        There may be either one centralised server or several
        distributed ones.  This model allows clients and servers to be
        placed independently on {nodes} in a {network}, possibly on
        different {hardware} and {operating systems} appropriate to
        their function, e.g. fast server/cheap client.
     
        Examples are the name-server/name-resolver relationship in
        {DNS}, the file-server/file-client relationship in {NFS} and
        the screen server/client application split in the {X Window
        System}.
