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 sp-ce 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 sp-ce, giving rise to warts like memory models in c and c++.
compare 32-bit application.
