Basic Introduction to Windows NT

WindowsNT is a Microsoft-oriented network operating system for workstations, Web servers, and mainframe computers, as well as PC operating systems.

It is tightly integrated with communication services, provides file and print services, can run client/server applications, has built-in internet/intranet functionality, and has gradually become a standard platform for enterprise networking.

New concepts introduced by Windows NT

1. NTFS (Windows NT File System): A new file system used in Windows NT. Provides secure access control and fault tolerance, which is more efficient than fat on large-capacity disks.

2. Sharing: Set certain permissions on network resources, without permission to access network resources.

3. User account: If you want to use network resources, you must have a user account.

Windows NT requires a legal account for both users and service programs.

An account that is created specifically for an application or service process is a service account that, when the system is started, uses a service account to log in to obtain the rights and permissions to use resources in the system.

A normal user account is provided by the user at logon, and is used for Windows NT to control the user's rights and permissions in the system, which is essentially indistinguishable from the service account.

4. Domain: is the basic unit of data security and centralized management in Windows NT. The network consists of a domain with a unique name.

A domain can be viewed as a system of servers running NT, with a group of computers sharing the same accounts and secure databases.

5. Working Group (Workgroup): A network structure with decentralized resources and systems management. In a working group, each computer is a peer-to-peer relationship, can be a server, or a workstation.

6. Right: Authorize a user to perform certain actions on the system. Rights are used to protect the system as a whole.

7. Permissions (Permission): Used to protect specific objects. Permissions specify how users of an object can be used and in what ways.

8. Security audits: Windows NT records the processes that occur on a computer that are related to security systems.

The following description is subject to Windows NT Server 4.0.

One. Main features of Windows NT

1.32-bit operating system, multiple boot function, can coexist with other operating systems.

2. Achieve preemptive multitasking and multithreaded operations.

3. Using SMP (symmetric multi-processing) 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. Interoperability with a variety of network operating systems, such as UNIX, novel Netware, Macintosh and other systems;

Provides extensive support for customer operating systems, such as MS-DOS, Windows, Windows NT Workstation, Uinx, OS/2, Macintosh, etc.

Support a variety of protocols: TCP/IP, NetBEUI, DLC, AppleTalk, NWLink and so on.

6. Safety meets U.S. Department of Defense C2 standards.

Two. Two versions of Windows NT

The two versions of Windows NT are Windows NT Workstation and Windows NT Server respectively.

The design goal of Windows NT Workstation is workstation operating system, which is suitable for interactive desktop environment.

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, only to adapt to the different application environment in the operational efficiency of the corresponding adjustment.

Windows NT Server has more advanced features that can be viewed as a subset of Windows NT Workstation.

Windows NT Server

1. Specifically for the server optimization, configuration requirements are high.

2. Supports up to 32 processors.

3. Can act as a network server, unlimited access to the client, complete heavy network tasks.

4. Up to 256 remote client access is supported.

5. Support for Macintosh files and printing, with disk fault-tolerant function.

Windows NT Workstation

1. The hardware is suitable for individual users, when the workstation like CAD/CAM and other advanced application requirements.

2. Only 2 processors can be supported.

3. Acting as a network server, you can connect to no more than 10 clients, complete the limited network service function.

4. Only one remote client access can be supported.

5. Does not support the Macintosh file and print, does not have the disk fault tolerance function.
