16bit application

Source : Free On-Line Dictionary of Computing

16-bit application
         Software for {MS-DOS} or {Microsoft
        Windows} which originally ran on the 16-bit {Intel 8088} and
        {80286} {microprocessors}.  These used a {segmented address
        space} to extend the range of addresses from what is possible
        with just a 16-bit address.  Programs with more than 64
        kilobytes of code or data therefore had to waste time
        switching between {segments}.  Furthermore, programming with
        segments is more involved than programming in a {flat address
        space}, giving rise to {warts} like {memory models} in {C} and
        Compare {32-bit application}.
