OS/2

Company / developer:
  IBM Corporation

OS/2

OS/2 is a computer operating system, initially created by Microsoft and IBM, then later developed by 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. OS/2 is no longer marketed by IBM, and IBM standard support for OS/2 was discontinued on December 31, 2006. Currently, Serenity Systems sells OS/2 under the brand name eComStation.



OS/2 was intended as a protected mode successor of PC-DOS and Microsoft Windows. Notably, basic system calls were modeled after MS-DOS calls; their names even started with "Dos" and it was possible to create "Family Mode" applications: text mode applications that could work on both systems. Because of this heritage, OS/2 is like Windows in many ways, but it also shares similarities with Unix and Xenix.



OS/2 is also remembered for being one of the first major operating system to have its own advocacy group. Team OS/2 was a grassroots, ad-hoc organization of volunteers, who promoted and supported the operating system and applications designed for it.

Microsoft Windows

Microsoft Windows is a family of operating systems by Microsoft. They can run on several types of platforms such as servers, embedded devices and, most typically, on personal computers. Microsoft first introduced an operating environment named Windows in November 1985 as an add-on to MS-DOS in response to the growing trend of graphical user interfaces (GUI) popularized by the Macintosh. Microsoft Windows eventually came to dominate the world's personal computer market.

MS-DOS

MS-DOS (short for Microsoft Disk Operating System) is an operating system commercialized by Microsoft. It was the most commonly used member of the DOS family of operating systems and was the dominant operating system for computers based on the Intel 8086 family of microprocessors, particularly the IBM PC and compatibles, during the 1980s. It was gradually replaced on consumer desktop computers by operating systems offering a graphical user interface (GUI), in particular by various generations of the Microsoft Windows operating system. It was originally known as QDOS (Quick and Dirty Operating System) and 86-DOS.

MS-DOS was originally released in 1981 and had eight major versions released before Microsoft stopped development in 2000. It was the key product in Microsoft's growth from a programming languages company to a diverse software development firm, providing the company with essential revenue and marketing resources. It was also the underlying basic operating system on which early versions of Windows ran as a GUI.

Name:OCX
File Type:ActiveX control file
Popularity:2
Category:System file
File Description:An OCX is an Object Linking and Embedding (OLE) custom control, a special-purpose program that can be created for use by applications running on Microsoft's Windows systems. OCXs provide such functions as handling scroll bar movement and window resizing. If you have a Windows system, you'll find a number of files in your Windows directory with the OCX file name suffix.
Object Linking and Embedding was designed to support compound documents (which contain multiple information types, such as text, graphic images, sound, motion video). The Windows desktop is an example of a compound document and Microsoft used OLE to build it. OLE and the Component Object Model (COM), a more general concept that succeeded OLE, support the development of "plug-and-play" programs that can be written in any language and used dynamically by any application in the system. These programs are known as components and the application in which they are run is known as a container. This component-based approach to application development reduces development time and improves the program capability and quality. Windows application development programs such as PowerBuilder and Microsoft Access take advantage of OCXs.
Microsoft now calls an OCX an ActiveX control, the component object under Microsoft's set of ActiveX technologies, of which the fundamental concept is the Component Object Model (COM) and, in a network, the Distributed Component Object Model (DCOM).
An OCX or ActiveX control is actually implemented as a dynamic link library DLL module. (You can think of a DLL program as a "subprogram" that can be used by any number of application programs, each of which is a "container" for the DLL or OCX/ActiveX control "object.") Visual Basic and C++ are commonly used to write OCX or ActiveX controls.
