OS/2 is anoperating system that was originally made by a joint agreement between theMicrosoft andIBM companies. The name stands for "Operating System/2". It was intended to replaceMS-DOS andMicrosoft Windows. OS/2 was maintained byIBM until 2006.
IBM discontinued its support for OS/2 on 31 December 2006. Since then, it has been updated, maintained and marketed under the nameeComStation. In 2015 it was announced that a new OEM distribution of OS/2 would be released that was to be calledArcaOS.
OS/2 had true multi-tasking. As a demonstration, ten 1 million line files were each put on display to screen in ten separate windows. On Windows 3.1, only one at a time had display activity. On OS/2, all ten displays moved uninterrupted simultaneously. IBM LAN Manager also had better measurable performance, being based on an OS/2 server. This was in the early 1990's.[1]
