What Is Windows NT What is Windows NT Windows NT is worked out on the base OS/2 NT. OS/2 is developed by Microsoft and IBM together. It has Microsoft OS/2 NT and IBM OS/2 two types. The two firms part on bad terms after cooperation. IBM continues to provide OS/2 version but Microsoft renames its OS/2 NT Wndows NT. That is the first generation of Windows NT 3.1. Windows NT is pure 32-bit operating system. It employs advanced NT core technology. NT stands for New Technology. --Source from http://www.powerdatarecovery.com/data-recovery/windows-nt.html Microsoft Windows NT (Network Termination) is a kind of operating system developed by Microsoft. Microsoft hires a few staffs from Digital Equipment Corporation to develop this new system. Many features of this system have showed the early conceptions with VMS, RSX-11, and DEC. Windows NT is the operating system for the workstation, networkserver, and large computer. It can also be used as PC operating system. It has a close relationship with communication services and provides file print service. It can run client/server applications, and it has built-in Internet/Intranet function. It is gradually becoming the standard platform of enterprise network. This article mainly introduces Wondows NT Server4.0. Features 1. 32-bit operating system. Multiple guide function. It is compatible with other operating systems. 2. It realizes the "preemptive" multitask and multithreading operation. 3. It uses SMP technology and supports multi-CPU system. 4. It supports CISC (such as Intel system) and RISC (such as Power PC, R440) and all kinds of hardware platform. 5. It can realize interoperate with various network operating systems. For example: UNIX, Novel Network, Macintosh, etc. It also provides wide support for the users' operating system, such as MS-DOS, Windows, Windows NT, Workstation, UINX, OS／2, and Macintosh. It supports various agreements: TCP／IP, NetBEUI, DLC, AppleTalk, and NWLINK, etc. 6. The security has satisfied the C2 standard of US Department of Defense. NT has the features of low price, high application, high security, abundant softwares. It is a popular network operating system. The disadvantages are the weaker file service function than NetWare, and too much occupation of serve resource. The two versions The two versions of Wondows NT are Windows NT Workstation and Wondows NT Server. The goal of Windows NT Workstation design is workstation operating system. It is used at the interactive desktop environment. The goal of Windows NT Server design is the enreprise-class network operating system. It provides easy management, fast reaction network environment. These two versions have the same structure but to adjust to different application environment they have some related changes with the operating efficiency. Windows NT Server has more advanced functions. Windows NT Workstation can be regarded as its subset. Windows NT Server 1. Optimized specially for the server, it requires higher configuration. 2. It supports 32 CPU at the most. 3. It can be used as network server and connected to clients with no limt to accomplish heavey network tasks. 4. It supports as many as 256 remote clients' access. 5. It supports Macintosh file and print and has a function of disc fault-tolerant. Windows NT Workstation 1. Hardware suits personal clients. When there are advanced applications like CAD/CAM in the workstation it is required to select and use. 2. It only supports 2 CPU. 3. It can act as network server and be connected to 10 or less clients to accomplish limited network service function. 4. It only supports one remote client's access. 5. It does not support Macintosh file and print and has not the function of disc fault-tolerant. New concept (1) NTFS (Windows NT Fiel System): the new file system employed by Windows NT. It provides secure access control and fault-tolerant function. It has higher efficiency than FAT in high-capacity disc. (2) Share: if the network resource is set with limitation, you cannot visit the resource without permission. (3) User Account: if you want to use network resource you have to get a user account. Windows NT requires legal account for the users and servicer. When starting up the system the service account created for applications or service process is needed for acquiring the permission and right to use the resource in the system. The common user's account is provided when the user log in. It is used for controlling the permission and right of the user. It is similar to the service account. (4) Domain: it is the basic unit of Windows NT data security and centralized management. Network is made uo by domains. Every domain has its unique name. It can be regarded as the system formed by servers that uses NT. A group of computers share the common account and secure data base. (5) Workgroup: a kind of network structures that resource and system management is separated. In the workgroup, every computer is reciprocal to each other. Every one computer can be server or workstation. (6) Right: the authorized user can run some operations in the system. Right is used to protect the whole system. (7) Perimission: it is used to protect specific object. Permission decides the users to use certain object and the way to use it. (6) Security examination: Windows NT will record all the processes related to security system. Windows NT got the bigger success than OS/2, because of its countless features and the market force of Microsoft. Development Team David N.Culter, the founder of NT project. After graduated from high school, he accepted the school scholarship and went to a small college Olivet in Michigan. He palyed football but quitted playing after breaking his leg when he was a sophomore. After graduating he got a job in DUPONT in January, 1965. His work needed computer modeling so he went to a computer programming school of IBM. A new computer series, Prism, was built by DEC but the project was canceled by DEC. Culter left DEC and that had been the rudiment of NT. A friend introduced Culter to the Microsoft, and there Microsoft started NT project. Through 5 years' hard working, with 1.5 billion dollars, more than 200 members, the epoch-making Window NT was developed. Bill Gates is a little afraid of Culter. Culter is hard and stern. He is against lazy, confused, and lack of competitiveness. He is not only a legend programmer, but also a great project manager. The project of Windows NT takes very long time, costs lots of money, and staffs. It may be the unprecedented project of history. Windows NT and the later Windows versions have almost unified the PC platform. That is a great contribution to the computer and software development. .

  • Windows NT Architecture Previous Screen Gilbert Held Payoff Windows NT Is a Sophisticated Operating System for Workstations and Network Servers
    50-30-19 Windows NT Architecture Previous screen Gilbert Held Payoff Windows NT is a sophisticated operating system for workstations and network servers. This article helps network managers to understand the communications capability of workstations and servers running on Windows NT, and data base administrators to determine the suitability of this platform for a structured query language (SQL) data base server. Introduction Windows NT is a 32-bit, preemptive multitasking operating system that includes comprehensive networking capabilities and several levels of security. Microsoft markets two version of Windows NT: one for workstations—appropriately named Windows NT Workstation—and a second for servers—Windows NT Server. This article, which describes the workings of the NT architecture, collectively references both versions as Windows NT when information is applicable to both versions of the operating system. Similarly, it references a specific version of the operating system when the information presented is specific to either Windows NT Workstation or Windows NT Server. Architecture Windows NT consists of nine basic modules. The relationship of those modules to one another, as well as to the hardware platform on which the operating system runs, is illustrated in Exhibit 1. Windows NT Core Modules Hardware Abstraction Layer The hardware abstraction layer (HAL) is located directly above the hardware on which Windows NT operates. HAL actually represents a software module developed by hardware manufacturers that is bundled into Windows NT to allow it to operate on a specific hardware platform, such as Intel X86, DEC Alpha, or IBM PowerPC. HAL hides the specifics of the hardware platform from the rest of the operating system and represents the lowest level of Windows NT.

  • Windows 10: Considered Harmful
    Windows 10: Considered Harmful 26 August, 2016 Last Updated: 25 September 2016 Previously I made a series of articles against Windows 10, consisting of basic explanation, open letters, and even a long-winded chance.org petition. However, I have come to realize that these various things could be better as one page rather than fragments across my website. On this page I hope to explain why the Windows 10 system is evil and also include why Windows as a whole is Considered Harmful . Sources to unreferenced items in this article can be found in the various resource links on the bottom of the page. Information can also be found in the photographs shown and with a simple web search. The primary reason against the Windows 10 system is an obvious one. The system is designed to be a system that data-mines the user. This is proven time and time again. Using a tool such as wireshark, one can clearly see that it makes encrypted connections to a variety of Microsoft servers. This uses a very weak RSA encryption that can be broken in under a minute. When a user successfully decrypted the encrypted data, he simply converted the decrypted ``.bin'' extension to ``.png'' and opened them. The image files were screen- shots of him installing the RSA decryptor tool. This was in a VM and was a fresh install. In addition to this, another user in Australia also monitored the odd connection but did not decrypt it. He noticed this when he opened a photograph in the Windows Photo App.

  • Windows Vista Short History of Windows
    Windows Vista The good and bad behind the hype Short History of Windows • 1983 - Bill Gates announces Microsoft will begin work on an OS with a Graphical User Interface. • 1984 - Apple airs a 30 sec commercial during the super bowl announcing the release of the Macintosh, the first (successful) GUI based computer. • 1985 - Windows 1.0 was first released in Nov. The release was considered a flop. • 1990 - Windows 3.0 is released with a substantial upgrade to the interface over Windows 1 and 2. This is the first commercially successful version of Windows. • 1993 - Windows NT 3.1 is released and is the first Microsoft OS not based in DOS. Microsoft would release separate versions of NT along with their DOS counterparts untill Windows XP • 1995 - Windows 95 is released as the first native 32 bit OS. Microsoft originally wanted to merge the NT and DOS platforms but due to backward compatibility issues and lacking hardware support of NT, Microsoft left NT out. 1 Short History of Windows • 1998 - Windows 98 is released. Microsoft integrates its web browser in the GUI and file manager. This opens up the floodgates for hackers to use the internet to infiltrate an entire computer or network. This move to integrate IE in to windows prompts a flood of anti-trust lawsuits from the US and several countries. Some cases are still active today. • 2000 - Windows 2000 is released. As with Windows 95, Microsoft planed Windows 2000 to be the bridge between the NT and DOS based OS’s, but was unsuccessful in that regard due to compatibility issues.
