server
     
        1. A program which provides some service to other ({client})
        programs.  The connection between client and server is
        normally by means of message passing, often over a network,
        and uses some {protocol} to encode the client's requests and
        the server's responses.  The server may run continuously (as a
        {daemon}), waiting for requests to arrive or it may be invoked
        by some higher level daemon which controls a number of
        specific servers ({inetd} on {Unix}).  There are many servers
        associated with the Internet, such as those for {Network File
        System}, {Network Information Service} (NIS), {Domain Name
        System} (DNS), {FTP}, {news}, {finger}, {Network Time
        Protocol}.  On Unix, a long list can be found in /etc/services
        or in the {NIS} database "services".  See {client-server}.
     
        2. A computer which provides some service for other computers
        connected to it via a network.  The most common example is a
        {file server} which has a local disk and services requests
        from remote clients to read and write files on that disk,
        often using {Sun}'s {Network File System} (NFS) {protocol} or
        {Novell Netware} on {IBM PC}s.
