Windows NT, a Microsoft Windows personal operating system, is designed for users and companies who need advanced functions. The first version of Windows NT was released on July 27, 1993. It is a multiprocessing and multi-user operating system that is independent from processor. With the software of MiniTool, partitions on Windows NT will be managed better. The technology of NT is the foundation of Microsoft’s operating system Windows 2000. It is said that Windows NT stands for Windows new technology at the very beginning, but Microsoft doesn’t claim it clearly. There is another version claims that NT refers to the simulator N 10 (ten) used by Microsoft to develop NT on the i860. The main design features of Windows NT are software and hardware portability. Due to the specific processor architectures, various versions are released. Windows NT 4.0 is an important one among these versions. The main goal of Windows NT is to create a common code base and create a hardware abstraction laye...
In fact, Windows NT contains Windows NT Workstation and Windows NT Server two versions. They have a different emphasis on functions. Windows NT Workstation is designed for workstation operating system, which is suitable for interactive desktop environment. While Windows NT Server is designed for companies’ operating system to provide an easy to manage, responsive network environment. The two are totally identical in system structure, but they are adjusted accordingly in order to adapt to different application environments. Compared with Windows NT Workstation, Windows NT Server has more advanced functions. And you can think of Windows NT Workstation as a subset of it. The next is a comparison between Windows NT Workstation and Windows NT Server:
As a personal computer operating system, Windows NT has some features. Main features of Windows NT will be listed in the below. If you want to learn more, please focus on those Windows NT features. 1. With multi-boot capability, Windows NT can coexist with other operating systems. 2. It implements preemptive multitasking and multithreading operations. 3. It supports multiple CPU systems with SMP (Symmetric Multiprocessing technology). 4. It supports a variety of hardware platforms such as CISI (Intel system) and RISC (such as Power PC, R400, etc.). 5.

The original version of Windows is a 16-bit GUI program which runs on MS-DOS and was written in Intel 8086 assembler. MS-DOS uses interrupts to call operating system services. 16-bit Windows is characterised by the use of 16-bit near pointers, 32-bit far pointers, and an awkward memory allocation system which requires the programmer to lock down a pointer to obtain a physical address and then release it so the operating system can relocate objects as needed to maximise efficiency. This was ma...
NT has grown from being called \\"Nice Try\\" to passing Unix in 2005 for sales of servers according to IDC, a market research firm based in Framingham, Mass. Others observe that Windows NT servers using IIS, ASP and ASP.NET by the 2000s had a diminishing share of web and corporate servers (under 30%) with UNIX dominating with over 70% of the market. The entry level $99 workstation Windows XP lacks the ability to run SQL Server databases and IIS web servers and other corporate features found in P...
When development started in November 1988, Windows NT (using protected mode) was to be known as OS/2 3.0, the third version of the operating system developed jointly by Microsoft and IBM. In addition to working on three versions of OS/2, Microsoft continued parallel development of the DOS-based and less resource-demanding Windows environment (using real mode). When Windows 3.0 was released in May 1990, it was so successful that Microsoft decided to change the primary application programming i...
The first release was given version number 3.1 to match the contemporary 16-bit Windows; magazines of that era claimed the number was also used to make that version seem more reliable than a '.0' release. The NT version is no longer marketed, but is said to reflect the degree of changes to the core of the operating system . The build number is an internal figure used by Microsoft's developers.
It is popularly believed that Dave Cutler intended the initialism 'WNT' as a pun on VMS, incrementing each letter by one, similar to the apocryphal story of Arthur C. Clarke deriving HAL 9000's name by decrementing each letter of IBM. While this would have suited Cutler's sense of humor, the project's earlier name of NT OS/2 belies this theory. Another of the original OS/2 3.0 developers, Mark Lucovsky, states that the name was taken from the Intel i860 processor—code-named 'N-Ten'—which serv...

The successor to Windows NT 3.51, Windows NT 4.0 introduced the user interface of Windows 95 to the Windows NT family, including the Windows shell, File Explorer (known as Windows NT Explorer at the time), and the use of "My" nomenclature for shell folders (e.g. My Computer). It also includes most components introduced with Windows 95.
Windows NT is a Microsoft Windows personal computer operating system designed for users and businesses needing advanced capability. NT's technology is the base for the Microsoft successor operating system, Windows 2000. Windows NT (which may originally have stood for "New Technology," although Microsoft doesn't say) is actually two products: Microsoft NT Workstation and Microsoft NT Server.
- User mode
- Kernel mode
The architecture of Windows NT, a line of operating systems produced and sold by Microsoft, is a layered design that consists of two main components, user mode and kernel mode. It is a preemptive, reentrant multitasking operating system, which has been designed to work with uniprocessor and symmetrical multiprocessor (SMP)-based computers. To process input/output requests, they use packet-driven I/O, which utilizes I/O request packets and asynchronous I/O. Starting with Windows XP, Microsoft beg
User mode is made up of various system-defined processes and DLLs. The interface between user mode applications and operating system kernel functions is called an "environment subsystem." Windows NT can have more than one of these, each implementing a different API set. This mechanism was designed to support applications written for many different types of operating systems. None of the environment subsystems can directly access hardware; access to hardware functions is done by calling into kern
Windows NT kernel mode has full access to the hardware and system resources of the computer and runs code in a protected memory area. It controls access to scheduling, thread prioritization, memory management and the interaction with hardware. The kernel mode stops user mode services and applications from accessing critical areas of the operating system that they should not have access to; user mode processes must ask the kernel mode to perform such operations on their behalf. While the x86 arch

Windows NT 3.1 is an operating system that was produced by Microsoft as part of the Windows NT family of operating systems. It was released on July 27, 1993. At the time of Windows NT's release, Microsoft's Windows 3.1 desktop environment had established brand recognition and market share; but Windows 3.1 relied on the DOS operating system for essential functions, and it had a constrictive 16-bit architecture. Windows NT, however, was a complete, 32-bit operating system that retained a desktop e
While Microsoft had a major foothold on the personal computer market due to the use of its MS-DOS as the de facto operating system of IBM PC compatibles, Nathan Myhrvold identified two major threats to Microsoft's monopoly—the RISC architecture, which proved to be more ...
In May 1990, Microsoft released Windows 3.0, a new version of its MS-DOS-based Windows desktop environment. Windows 3.0 sold well, and the resulting shift in Microsoft's marketing strategy eroded their partnership with IBM—who wanted Microsoft to concentrate solely on ...
Windows NT 3.1 and Windows NT 3.1 Advanced Server were released on July 26, 1993. At first, only the x86 and MIPS versions shipped; the DEC Alpha version followed in September. Microsoft sold the workstation version for $495, and the server version for $1,495. Ostensibly, the ser
Cutler set three main goals for Windows NT. The first goal was portability: in contrast to previous operating systems, which were strongly tied to one architecture, Windows NT should be able to operate on multiple architectures. To meet this goal, most of the operating systems, including the operating system core, had to be written in the C programming language. During the planning phase it was clear that this would cause Windows NT to have higher memory consumption than all previous operating s
While Windows NT 3.1 uses the same graphical user interface as Windows 3.1, it was developed anew. The operating system is not DOS-based, but an independent 32-bit operating system; many concepts were taken from Cutler's previous operating system, VMS. The architecture of Windows
Windows NT 3.1 provides a boot manager called NTLDR which is loaded during the startup process of the operating system on x86-based computers. It allows a multiboot setup of multiple instances of Windows NT 3.1, as well as MS-DOS and OS/2 1.x. NTLDR is not used for the RISC versi
Windows NT 3.1, for the most part, comes with 32-bit versions of the components featured in Windows 3.1 and Windows for Workgroups. However, it also included applications specifically aimed at the needs of Windows NT, like the User Manager, the Performance Monitor, the Disk Admin
Windows NT 3.1 supports multiple platforms: Aside from the x86 architecture, it runs on computers with DEC Alpha or MIPS processors. Minimum system requirements on x86 systems include a 25 MHz 80386 processor, at least 12 megabytes of memory, 75 megabytes of hard drive space, and a VGA graphics card. RISC systems require 16 megabytes of memory, 92 megabytes of hard drive space, and a CD-ROM drive. The Advanced Server edition requires an 80386 processor with 16 megabytes of memory and 90 megabyte
Windows NT 3.1 sold about 300,000 copies in its first year. The hardware requirements were deemed to be very high at that time; the recommended system requirements of a 486 processor with 16 megabytes of memory were well above the average computer's configuration, and the operating system turned out to be too slow to use. 32-bit applications which could have used the capabilities of Windows NT 3.1 were scarce, so users had to resort to the old 16-bit applications; however, these ran slower than
NTFS (NT file system; sometimes New Technology File System) is the file system that the Windows NT operating system uses for storing and retrieving files on a hard disk. NTFS is the Windows NT equivalent of the Windows 95 file allocation table (FAT) and the OS/2 High Performance File System (HPFS). However, NTFS offers a number of improvements over FAT and HPFS in terms of performance, extendibility, and security.
When a hard disk is formatted (initialized), it is divided into partitions or major divisions of the total physical hard disk space. Within each partition, the operating system keeps track of all the files that are stored by that operating system. Each file is actually stored on the hard disk in one or more clusters or disk spaces of a predefined uniform size. Using NTFS, the sizes of clusters range from 512 bytes to 64 kilobytes. Windows NT provides a recommended default cluster size for any given drive size. For example, for a 4 GB (gigabyte) drive, the default cluster size is 4 KB (kilobytes). Note that clusters are indivisible. Even the smallest file takes up one cluster and a 4.1 KB file takes up two clusters (or 8 KB) on a 4 KB cluster system.
When a file is created using NTFS, a record about the file is created in a special file, the Master File Table (MFT). The record is used to locate a file's possibly scattered clusters. NTFS tries to find contiguous storage space that will hold the entire file (all of its clusters).
Windows NT is an older version of Windows released in the 1993. All the subsequent versions of Windows are a part of the Windows NT family. The Sandboxie application on the computer uses the Windows NT environment to function. This is potentially harmless for you.
