service

    Work performed (or offered) by a
   server.  This may mean simply serving simple requests for
   data to be sent or stored (as with file servers, gopher or
   http servers, e-mail servers, finger servers, SQL
   servers, etc.); or it may be more complex work, such as that
   of irc servers, print servers, X Windows servers, or
   process servers.

   E.g. "Access to the finger service is restricted to the
   local subnet, for security reasons".
