OS/2 is an operating system developed by IBM and originally intended to be the successor to MS-DOS. The project was initiated in the mid-1980s as a collaboration between IBM and Microsoft, but after a falling out between the companies, IBM continued the development of OS/2 on its own. OS/2 was designed to run on personal computers and provided a graphical user interface (GUI), multitasking capabilities, and support for 32-bit applications.
