Difference Between Windows and OS2
Windows and OS/2 are two operating systems that have played significant roles in the history of personal computing. While Windows has emerged as the dominant operating system for desktop and laptop computers, OS/2 had its moment in the spotlight before gradually fading into obscurity.
What is Windows OS?
Windows is a widely used operating system developed by Microsoft. It provides a graphical user interface (GUI) that allows users to interact with their computers easily. Windows has evolved over the years, with the latest version being Windows 10.
Here are some important features of Windows OS −
User-friendly interface − Windows offers a user-friendly interface, making it accessible to a wide range of users, from beginners to advanced professionals. It supports multitasking, allowing users to run multiple applications simultaneously. Windows also provides a vast ecosystem of software, including productivity tools, games, and multimedia applications.
Regular updates and security patches − Microsoft regularly releases updates and security patches to ensure the stability and security of the operating system. Windows has a strong focus on backward compatibility, allowing users to run older software and hardware with ease. It also supports a wide range of devices, including desktops, laptops, tablets, and smartphones.
Evolution of Windows − Throughout its history, Microsoft has introduced several major versions of Windows, including Windows 95, Windows XP, Windows 7, and Windows 10. Each version brought new features, improvements in performance, and enhancements to the user interface.
Cortana − Windows 10, the most recent version, introduced a unified platform for desktops, laptops, and tablets. It introduced the concept of universal apps, allowing developers to create applications that run across various Windows devices. Windows 10 also introduced the virtual assistant Cortana and integrated the Microsoft Store for downloading applications.
Windows is a popular operating system developed by Microsoft that provides a user-friendly interface, extensive software support, and compatibility with a wide range of devices. It has evolved over the years, with Windows 10 being the latest version, offering a unified experience across different devices.
What is OS/2?
OS/2, short for Operating System/2, is a computer operating system that was initially developed as a collaboration between IBM and Microsoft in the late 1980s. OS/2 was designed to be a successor to MS-DOS (Microsoft Disk Operating System) and was intended to provide a more advanced and robust platform for both business and personal computing.
Here are some key features of OS/2 −
Development of OS/2 − The development of OS/2 began in 1985, with IBM and Microsoft aiming to create a multitasking operating system that could take advantage of the emerging 32-bit processors. The first version, OS/2 1.0, was released in 1987, but it failed to gain widespread adoption due to compatibility issues and limited software support. However, with the release of OS/2 2.0 in 1992, the operating system started gaining attention and recognition.
Challenges and Decline − OS/2 2.0 featured a significantly improved user interface and introduced the Workplace Shell (WPS), a graphical shell that provided a more intuitive and user-friendly experience. It supported preemptive multitasking, allowing multiple applications to run simultaneously without affecting system performance. OS/2 also offered better memory management, enhanced stability, and improved device driver support.
Virtual DOS Machine − One of the notable features of OS/2 was its ability to run MS-DOS and Windows applications through a compatibility layer called the "Virtual DOS Machine" (VDM). This made it possible for users to migrate from MS-DOS to OS/2 without losing access to their existing software library. OS/2 could run Windows 3.0 applications in a separate window, offering users a seamless transition.
Collaboration − Despite its technical advancements, OS/2 faced several challenges that hindered its widespread adoption. One of the major obstacles was the growing dominance of Microsoft's Windows platform. As Microsoft focused more on Windows development, the collaboration between IBM and Microsoft gradually deteriorated, leading to IBM taking over the development of OS/2 on its own.
The release of Windows 95 in 1995, with its improved user interface and broader software support, further diminished the market share of OS/2. IBM continued to develop newer versions of the operating system, such as OS/2 Warp 3 and Warp 4, which introduced additional features like internet connectivity and Java support. However, the momentum had shifted in favor of Windows, and OS/2 struggled to compete effectively.
IBM officially discontinued OS/2 in 2001, although a small group of enthusiasts and developers continued to support the platform through independent initiatives. Today, OS/2 remains a niche operating system, primarily used in specialized environments where its specific features and strengths are still relevant.
In summary, OS/2 was an advanced operating system developed by IBM and Microsoft as a successor to MS-DOS. It offered preemptive multitasking, a graphical user interface, and the ability to run MS-DOS and Windows applications. While it made significant technical advancements, OS/2 faced challenges from Windows and eventually lost mainstream popularity. Nevertheless, it retains a dedicated user base among enthusiasts and certain specialized applications.
