OS/2 and its Legacy in Operating Systems
OS/2 (Operating System/2) is a proprietary computer operating system initially developed by IBM and Microsoft. OS/2 was designed for x86 and PowerPC based personal computers. The operating system was introduced as a part of the same generation release as IBM's Personal System/2 (PS/2) line of second-generation PCs.
Development and History
OS/2 was intended as a protected-mode successor to PC DOS targeting the Intel 80286 processor. The development of OS/2 started in the early 1980s, aiming to surpass the capabilities of MS-DOS. The operating system was known for its advanced features for the time, including a graphical user interface and support for multitasking.
The collaboration between IBM and Microsoft eventually ended in a feud by 1990, leading Microsoft to focus on developing Windows, while IBM continued with OS/2 development. OS/2 Warp 4, released in 1996, was the last major upgrade, as IBM began to phase out the product, unable to compete with the widespread adoption of Windows. Updated versions of OS/2 were released until 2001.
Features and Technical Specifications
OS/2 shared commonalities with Unix, Xenix, and Windows NT. Basic system calls were modeled after MS-DOS calls, and their names even started with "Dos." The system supported "Family Mode" applications, which were text mode applications that could work across different operating systems.
OS/2's Influence and Legacy
The development and release of OS/2 were significant milestones in the history of operating systems. Despite its eventual decline, OS/2 influenced various aspects of subsequent operating systems, particularly in terms of user interface design and system architecture.
