16-bit application
<operating system> 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
C++.

32-bit application.
