#REDIRECT [[16-bit computing#16-bit application]]
A '''16 bit application''' is any software written for [[MS-DOS]], OS/2 1.x or early versions of [[Microsoft Windows]] which originally ran on the [[16-bit]] [[Intel 8088]] and [[Intel 80286]] [[microprocessor]]s. Such applications used a 20-[[bit]] or 24-bit [[memory segment|segment or selector-offset]] address representation to extend the range of addressable memory locations beyond what was possible using only 16-bit addresses. Programs containing more than <math>2^{16}</math> [[byte]]s (64 [[kibibyte]]s) of instructions and data therefore required special instructions to switch between their 64-kibibyte [[memory segment|segment]]s, increasing the complexity of programming 16-bit applications.
