Network File System
     
         (NFS) A {protocol} developed by
        {Sun Microsystems}, and defined in {RFC 1094}, which allows a
        computer to access files over a network as if they were on its
        local disks.  This {protocol} has been incorporated in
        products by more than two hundred companies, and is now a {de
        facto} standard.  NFS is implemented using a {connectionless
        protocol} ({UDP}) in order to make it {stateless}.
