Abstract


In my work I would describe the history of the operating system 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 31 December 2006. Currently, Serenity Systems International sells OS/2 under the brand name eComStation.

World OS/2 is the whole set of systems based on base component - OS/2 Warp operating system. Which all charm that it, similarly to designer Lego, represents a set of "cubes" from which, if necessary, it is possible to collect practically any required configuration for execution of this or that task.

Thus, frequently, it is possible to do without additional expenses and efforts on support from the manufacturer. There are different versions and modifications OS.

Experience of the Russian and foreign users shows, that OS/2 has steady positions on a line of personal application in domestic conditions, in quality highly resistant, the protected system with more modest requirements to the equipment, than for other systems.

OS/2 Warp perfectly opens possibilities of Internet and has wide choice of the daily software.

Client OS/2 Warp system and OS/2 Warp Server will derivate a complete spectrum of services and solutions on small and average business, and also on the remote clients.

The openness of the platform, support of open standards, scalability of the system, convenient object graphic interface, Unix-organization of stack TCPIP, support practically all network protocols, good compatibility with a DOS / Win applications - makes all this OS/2 by universal choice for many tasks.

Development history


History OS/2 starts in 1987 when IBM Corp. together with Microsoft have decided to develop the new operating system for personal computers. The Microsoft appeared together with an IBM therefore as already cooperated with an IBM, having developed the MS DOS (more precisely speaking, the MS DOS was bought by the corporation of Microsoft in due time).

Already then the fact of becomes clear that the DOS long cannot exist on arena of operating systems by virtue of the limitation though, first of all, the new operating system reflects for new computers range IBM PS/2 on the basis of MCA architecture. One of main assignments - the functional link of personal COMPUTERS with mainframe computers (mainframes).

The new stage of development of operating systems has affected the name; new operating system was christened by the operating system of the second generation, in abbreviated form - OS/2 and is ordered the .....[read full text]

  • Autumn of 1994 - OS/2 Warp 3.0. In a general plan, changes have touched only improvement of productivity of the system, lowering of the requirement to the RAM up to 4 Mbytes. The spectrum of supported hardware devices is extended. Has appeared new element —Launch Pad — the effective and floppy resource perfectly entered in object-oriented model of the interface.

    With OS/2 Warp 3.0 it is delivered the free-of-charge "BonusPak package including resources of audit of hardware, the extended viewers of a multimedia, processing of moved video, full-function operation with a fax (at presence of a fax-modem), powerful enough package of office applications (including the word processor, spreadsheets, the database e, constructions of diagrams) and personal Organizer, a resource of holding conferences in networks, access to CompuServe networks and Internet.

  • September 26, 1996 appears following OS/2 version - Warp 4.0, "Marylin's". In this version complete handle of a voice, resources of the voice text entering, built - in mechanisms Java, OpenDoc is included, resources of operation in a wide-area network of Internet and other high technologies developed by corporation of an IBM. The design of the system is strongly changed and it is more successful (concerning the previous versions netw.....

  • After IBM and Microsoft went their separate ways, Microsoft overhauled its version of OS / 2, Windows NT, and the very OS / 2 continued to develop the company IBM, which is still not paid this operating system due attention.

    May 21, 1990 came Windows 3.0.
    During the first month of its copies have been sold more than copies of OS / 2 for three years.
    Microsoft dominates the office software market for Windows.

    In 1991, Microsoft discontinued participation in the development of OS / 2, developed a hardware-independent OS renamed from «OS / 2, Version 3" «Windows NT».

    Version of OS / 2 Warp 3 seriously considered as a worthy competitor to Windows, but version 4 is no longer lay claim to it because of advertising Microsoft.
    October 26, 1996 came the next version - OS / 2 Warp 4.0 (Merlin).
    In 1999 appears the OS / 2 Warp Server for e-business (code-named "Aurora", a version of the system - 4.5).

    It is also interesting that in the process of collaboration, Microsoft created Windows for a much more user-friendly end-user code, relative to that of OS / 2 v1.10SE and OS / 2 v1.20.
    That is, in particular, all the kernel code and interfaces related to device drivers.

    Example procedure the printer in early versions of OS / 2:

    1) install device drivers;

    2) install the printer queue;

    3) create a printer;

    4) compare the device driver with the object of the printer;

    5) compare the print queue with the printer object;

    6) set COM-port for the printer connected to onomu port;

    7) with the SPOOL command to reassign the printer to the desired port;

    8) to determine the optional printer settings.

    Microsoft, officially refuse to support OS / 2 continues to follow closely the development of this operating system.
    Many details of the interface OS / 2, IBM and Microsoft have moved into a new operating system Microsoft - Windows 95.
