What is the format used by the Windows NT operating system?


Windows NT is a network operating system for workstations, network servers and large computers introduced by Microsoft. It can also be used as a PC operating system. It is tightly integrated with communication services, provides file and print services, runs client/server applications, and has built-in Internet/Intranet capabilities, making it a standard platform for enterprise networking. This article describes Windows NT Server 4.0 as the standard. 1. The main features of Windows NT 132-bit operating system, multi-boot function, can coexist with other operating systems. 2 Implemented "preemptive" multitasking and multithreading operations. 3 uses SMP (Symmetric Multiprocessing) technology to support multiple CPU systems. 4 support CISC (such as Intel system) and RISC (such as Power PC, R4400, etc.) a variety of hardware platforms. 5 can interoperate with various network operating systems. Such as: UNIX, Novel Netware, Macintosh and other systems; provide extensive support for customer operating systems, such as MS-DOS, Windows, Windows NT Workstation, UINX, OS/2, Macintosh, etc.; support multiple protocols: TCP /IP, NetBEUI, DLC, AppleTalk, NWLINK, etc. 6 Security meets the US Department of Defense's C2 standard. 2. Two versions of Windows NT Two versions of Windows NT are Windows NT Workstation and Windows NT Server. Windows NT Workstation is designed to be a workstation operating system for interactive desktop environments; Windows NT Server is designed to be an enterprise-class network operating system that provides an easy-to-manage, responsive network environment. The two are exactly the same in the system structure, but they are adjusted accordingly in order to adapt to different application environments. Windows NT Server has more advanced features that treat Windows NT Workstation as a subset of it. Windows NT Server Windows NT Workstation is optimized for the server, and the hardware is suitable for individual users, when there are high configuration requirements on the workstation. Advanced applications such as CAD/CAM are required. Supports up to 32 processors. Can support 2 processors. Acting as a network server, it can act as a network server without restrictions, and can connect to the client without exceeding the heavy network tasks. 10 clients, complete limited network service functions. Supports up to 256 remote clients. Only one remote client access can be supported at the same time. Supports Macintosh files and printing, does not support Macintosh files and printing, and does not have disk fault tolerance. Disk fault tolerance. 3. New concepts introduced by Windows NT (1) NTFS (Windows NT File System): A new file system used by Windows NT. It provides secure access control and fault tolerance, and it is more efficient than FAT on large capacity disks. (2) Sharing: Set a certain permission for the network resources, and you cannot access the network resources without permission. (3) User Account: In order to use network resources, there must be a user account. Windows NT requires a legitimate account for both users and service programs. An account-as-a-service account created specifically for an application or service process. At system startup, the service process logs in using the service account to obtain rights and permissions to use resources in the system. The normal user account is provided by the user when logging in, and the right and authority for Windows NT to control the user in the system is essentially the same as the service account. (4) Domain: It is the basic unit of data security and centralized management in Windows NT. A network consists of domains with unique names. A domain can be thought of as a system of servers running NT, with a group of computers sharing the same account and secure database. (5) Workgroup: A network structure in which resources and system management are dispersed. In the work group, each computer is a peer-to-peer relationship, and each can be a server or a workstation. (6) Right: Authorize a user to perform certain operations on the system. Rights are used to protect the system as a whole. (7) Permission: Used to protect specific objects. Permissions can be used by users of an object and by what method. (8) Security audit: Windows NT will record the various security-related processes that occur on the computer
