the early development of the Windows operating system that is phenomenal

 Windows is a family of personal computer operating system developed by Microsoft that uses the graphical user interface (graphical user interface).Windows operating systems have evolved from MS-DOS, an operating system based on text mode and command-line. The first version of Windows, Windows Graphic Environment 1.0 was first introduced on 10 November 1983, but only out of the market in November 1985 designed to meet the needs of the computer to display a picture. Windows 1.0 is a software 16-bit (not an operating system) running on top of MS-DOS (and some variants of MS-DOS), so he will not be able to walk without the DOS operating system. Version 2.x, 3.x versions are the same. Recent versions of Windows (starting from version 4.0 and Windows NT 3.1) is an independent operating system that no longer depend on the operating system MS-DOS. Microsoft Windows and can be developed and can be controlled using the operating system up to 90%.Windows 1.0The first version of Microsoft Windows, called Windows 1.0, released on 20 November 1985. This version has many shortcomings in some functionality, making it less popular in the market. At first Windows version 1.0 is about to be named by the Interface Manager, but Rowland Hanson, head of marketing at Microsoft Corporation, Microsoft convinced the company that the name "Windows" will be "luring" consumers. Windows 1.0 is not a complete operating system, but only extending the capabilities of MS-DOS with a graphical interface enhancements. In addition, Windows 1.0 also has the same problems and weaknesses that are owned by MS-DOS.

 Windows 2.xWindows version 2 came out on December 9, 1987, and became a little more popular than its predecessor. Most gained in popularity because of its proximity to the graphics application Microsoft, Microsoft Excel for Windows and Microsoft Word for Windows. Windows applications can be run from MS-DOS, and then enter the Windows to perform the operation, and will come out by itself when the application is closed.Microsoft Windows finally gained a significant improvement when Aldus PageMaker appeared in versions for Windows, which previously could only run on the Macintosh. Some computer historians date this, the emergence of a significant application that behavior other than by Microsoft as an early success of Windows.Windows 2.1xFurthermore, two new versions are released, the Windows / 286 2.1 and Windows / 386 2.1. As with previous versions of Windows, Windows / 286 uses real-mode memory model, but it was the first version to support the High Memory Area (HMA). Windows / 386 2.1 has a kernel running in protected mode with emulation Expanded Memory Specification (EMS) standard Lotus-Intel-Microsoft (LIM), the predecessor specifications Extended Memory Specification (XMS) which would finally change the topology of computing at the IBM PC. All Windows and DOS-based application when it was run in real mode, which is running over the protected mode kernel by using the virtual 8086 mode, which is a new feature which is owned by Intel 80386.Windows 3.0Windows 3.0 can run in three modes, namely real mode, standard mode, and 386 Enhanced mode, and is compatible with Intel family of processors from Intel 8086/8088, 80286, to 80386 Windows 3.0 will try to detect which mode will used, although the user can force the Windows work in a certain mode using certain switches when running

    win / r: force Windows to run in real mode
    win / s: force Windows to run in standard mode
    win / 3: force Windows to run in 386 Enhanced mode.Version 3.0 is also the first version of Windows that runs in protected mode, although the 386 enhanced mode kernel is an enhanced version of the protected mode kernel in Windows / 386.Because of the backward compatibility feature, Windows 3.0 applications to be compiled by using the 16-bit environment, so that did not use the capabilities of the Intel 80386 microprocessor, which is actually a 32-bit processor.OS / 2Microsoft and IBM work together to develop a successor to the DOS operating system, called OS / 2. OS / 2 can use all the capabilities offered by Intel 80286 microprocessor and a memory capable of accessing up to 16 Megabytes. OS / 2 1.0 was released in 1987, which features the swapping and multitasking, in addition of course to allow MS-DOS applications to run on it.In the early 1990s, the relationship between Microsoft and IBM was stretched due to the appearance of a conflict. This is because they work together in developing a personal computer operating systems respectively (IBM OS / 2 and Microsoft with its Windows), both have access to the code of each operating system. Microsoft requires further development of the Windows operating system made, while IBM has a desire that all future work should be made based on the operating system OS / 2. In an attempt to put an end to this conflict, IBM and Microsoft agreed that IBM would develop OS / 2 version 2.0, to replace the OS / 2 version 1.3 and Windows 3.0, while Microsoft had to develop a new operating system, OS / 2 version 3.0, which will then replace the OS / 2 version 2.0. This approval did not last long, so that IBM and Microsoft relationship was terminated. IBM eventually continue the development of OS / 2, while Microsoft changed the name of the operating system OS / 2 version 3.0 (not yet released) into Windows NT.WINDOWS 3.1Microsoft developed Windows 3.1, which offers some minor improvements to Windows 3.0 (as well as the ability to display the Fonts TrueType fonts, developed jointly with Apple), and also contained in it a lot of fixes to bugs and support for multimedia. Version 3.1 also removes support for real mode, so it only runs on the protected mode which only the Intel 80286 microprocessor or higher.WINDOWS NTThe main architect of Windows NT is Dave Cutler, who was one of the leaders of the VMS operating system architect in the company Digital Equipment Corporation (DEC), which was later bought by Compaq which is now part of Hewlett-Packard. Support device drivers for Windows NT is also not so much because it develops drivers for Windows NT is considered complicated by some developers, in addition to Windows NT also has superiority in hardware abstraction model. Which made Windows NT perfect choice for server market share local area network (LAN), which in 1993 is experiencing a massive boom, along with commodity network in the office has increased dramatically. Networking features in Windows NT offers several connectivity options are extensive network and also of course the NTFS file system that is efficient.Windows NT was the first Windows operating system that is made using a hybrid kernel, after the previous versions using only a single monolithic kernel only.Windows 95on August 24, 1995. Microsoft has two advantages of this launch: 1) it is impossible for consumers to run Windows 95 DOS operating system instead of Microsoft's much cheaper;2) although traces of DOS were never completely removed from the operating system, even versions of the plug a DOS version to be published as part of the boot process, Windows 95 running on its own in 386 Enhanced mode, using virtual memory and the model memory addressing flats 32-bit. Features that make Win32 applications for virtual RAM maximum of 2 gigabytes (with 2 gigabytes rest are reserved for the operating system). USB support in Windows 98 was also much better than its predecessor.Before replacing it with a new version of Windows, Microsoft released Windows 95 in five different versions, namely as follows:

    Windows 95 - the actual release of Windows 95
    Windows 95 A - includes updates Windows 95 Original Service Release 1 (OSR1) which is entered directly on the installation.
    Windows 95 B - includes several other major updates, such as the FAT32 file system, and Internet Explorer 3.0. This version is also known as the Windows 95 OSR2, or many people in Indonesia call it Windows 97.
    Windows 95 and USB - Windows 95 or Windows 95 OSR2.1 is a version that offers hardware support for bus-based Universal Serial Bus / USB.
    Windows 95 C - or Windows 95 OSR2.5 includes all the above features, plus Internet Explorer 4.0. This version is the most recently released version of Windows 95 series.WINDOWS NT 4.0

 NT 4.0 has the same interface with Windows 95, but using the same kernel with Windows NT, so it is more stable. Indeed, there is an additional patch available for Windows NT 3.51 NT 3.51 that can make so much like NT 4.0, but it is not very stable and has a lot of bugs.Windows NT 4.0 comes in four versions:

    Windows NT 4.0 Workstation
    Windows NT 4.0 Server
    Windows NT 4.0 Server, Enterprise Edition (which includes support for clustering and up to 8-way SMP)
    Windows NT 4.0 Terminal ServerWINDOWS 98

 On June 25, 1998, Microsoft released a new Windows operating system, known as Windows 98. Windows 98 was considered as a minor revision of the Windows 95, but is generally viewed much more stable and reliable than its predecessor, Windows 95. Windows 98 includes many new hardware drivers and support for the FAT32 file system that better allow partitions to have a capacity greater than 2 gigabytes, a restriction contained in the Windows 95 and USB support in Windows 98 was also much better than its predecessor.In 1999, Microsoft released Windows 98 Second Edition, a release that offers many improvements over previous versions. Internet Connection Sharing, which is a form of Network Address Translation, which allows multiple machines within a local network in order to use a single Internet connection line together was introduced in this version. Many minor problems in Windows that long has been corrected, which makes the Windows 98 by many people as a version of Windows 9x most stable among all other versions of Windows 9x.WINDOWS 2000on February 17, 2000, an earlier version known as Windows NT 5.0 or "NT 5.0". The Windows 2000 version is intended for two market share, the market share of the workstation and server market share.Among the features of Windows 2000 the most significant is the Active Directory, a network model replacement for the NT network domain, using technology that is the industry standard, such as Domain Name System (DNS), Lightweight Directory Access Protocol (LDAP) and Kerberos to connects a machine to other woods.Windows 2000 is available in six editions, namely:

    Windows 2000 Professional
    Windows 2000 Server
    Windows 2000 Advanced Server
    Windows 2000 Datacenter Server
    Windows 2000 Advanced Server Limited Edition
    Windows 2000 Datacenter Server Limited EditionWindows 2000 is available in six editions, namely:

            Windows 2000 Server
            Windows 2000 Advanced Server
            Windows 2000 Datacenter Server
            Windows 2000 Advanced Server Limited Edition
            Windows 2000 Datacenter Server Limited EditionWINDOWS MEIn September 2000, Microsoft introduced the Windows Millennium Edition. The updated version of Windows 98 with multimedia support and better Internet. This version also includes the "System Restore," which allows users to restore the system to a point known fine, when operating systems fail. The features contained in Windows Me (such as Internet Explorer 5.5, Windows Media Player 7.0, and Microsoft DirectX 7.1) can even be obtained for free from the Windows Update site, except for System Restore. As a result, Windows Me was not considered as an operating system that is unique among his brothers of the family Windows 9x, Windows 95 and Windows 98. Windows Me was also criticized because of the emergence of stability problems, and also support for MS-DOS running on the mode real. People even called Windows Me as Windows Mistake Edition.
