flat
     
        1. Lacking any complex internal structure.  "That {bitty box}
        has only a flat file system, not a hierarchical one."  The verb
        form is {flatten}.  Usually used pejoratively (at least with
        respect to file systems).
     
        2. Said of a memory architecture like that of the {VAX} or
        {Motorola} {680x0} that is one big linear address space
        (typically with each possible value of a processor register
        corresponding to a unique address).  This is a {Good Thing}.
        The opposite is a "{segmented}" architecture like that of the
        {Intel 80x86} in which addresses are composed from a
        base-register/offset pair.  Segmented designs are generally
        considered cretinous.
     
        3. A flat {domain} is one where all elements except {bottom}
        are incomparable (equally well defined).  E.g. the integers.
