Which of the following operating systems is produced by IBM?
A
OS-2
B
Windows
C
DOS
D
UNIX
Correct Answer: OS-2
OS/2 is a series of computer operating systems, initially created by Microsoft and IBM under the leadership of IBM software designer Ed Iacobucci. As a result of a feud between the two companies over how to position OS/2 relative to Microsoft's new Windows 3.1 operating environment, the two companies severed the relationship in 1992 and OS/2 development fell to IBM exclusively.The name stands for "Operating System/2", because it was introduced as part of the same generation change release as IBM's "Personal System/2 (PS/2)" line of second - generation personal computers. The first version of OS/2 was released in December 1987 and newer versions were released until December 2001.
