  2. 2. Microsoft Windows NT Microsoft Windows NT (Windows quot;New Technologyquot;) is an operating system produced by Microsoft Corporation. It was originally based on OS/2 3.0, a joint project between Microsoft and IBM. The collaboration fell apart, and IBM continued to market the previous version OS/2 3.0 (later rebranded OS/2 Warp) while Microsoft renamed their version to MS Windows NT, changing the main API to a 32- bit version of its MS Win16 API. Microsoft hired a group of developers from Digital Equipment Corporation to build a new system. Many elements of NT reflect the earlier DEC experience with VMS and RSX-11 NT enjoyed more success than OS/2, due to its feature promises that were never fully realized and to Microsoft's market prowess. The following are the major releases of Windows NT : • Microsoft Windows NT 3.1 • Microsoft Windows NT 3.5 • Microsoft Windows NT 3.51 • Microsoft Windows NT 4.0 Microsoft Windows 2000 and Windows XP are later versions of Windows NT: • Microsoft Windows 2000 (Version 5.0) • Microsoft Windows XP (Version 5.1) Windows NT is now simply called Windows: • Microsoft Windows Server 2003 (Version 5.2) Version 3.1, the first version based on quot;NT Technologyquot; (which may have been numbered perhaps to match that of Windows 3.1, or perhaps to best OS/2 Warp 3), came in quot;Advanced Serverquot; and quot;Workstationquot; editions. From Version 3.5, quot;Advanced Serverquot; was renamed quot;Serverquot;. From Version 5.0 (Windows 2000) onwards, quot;Workstationquot; was renamed quot;Professionalquot;. A quot;Home Editionquot; was introduced with Version 5.1 (XP), to mark the discontinuation of the previous MS-DOS based Windows system. 1|Page
  3. 3. The acronym WNT was acknowledged by its ex-Digital developer, Dave Cutler, to be a pun on VMS -- obtained by shifting each letter one position in alphabetical order, akin to the urban legend regarding the name of IBM and the villanous computer HAL 9000, as featured in the film 2001: A Space Odyssey. NT uses a highly layered design, with the hardware hidden from the NT kernel by a hardware abstraction layer, and most operating system API functionality provided by API-specific interface modules that present specific functionality such as the Win32, OS/2, DOS and POSIX system call compatibility environments. In 1993, when it was first released, Microsoft Windows NT was Microsoft's platform of choice for high-end systems. The current version, 4.0, is intended for use as a network server (NT Server) or a workstation (NT Workstation). Windows NT did not replace Windows 95. While Windows NT contains the Windows 95 interface, it is entirely 32-bit. For more information on the differences between Windows 95 and NT 4.0, see the Knowledge Base document What are the differences between Windows 95 and Windows NT Workstation 4.0? Technical features of Windows NT • Interface Contains the Windows 95 interface and features like the Start button, o Taskbar, Explorer, Network Neighborhood, and Briefcase • Networking NetWare client and login script support o Enhanced meta-file (EMF) spooling for improved network printing o speed Support for 15 network protocols o Peer-to-peer and FTP server capabilities o Client software for both telnet and FTP services o • Messaging Capabilities Windows Messaging Subsystem o Microsoft Exchange and Microsoft Schedule+ included o WINCHAT, NET MESSAGE, or NetDDET o 2|Page
