Among the key features of NT’s multitasking priority MultiRead processes or threads, portability and support for symmetric multiprocessing. The priority allows multitasking multitasking preferred and subordinated. NT is not the specific programs should be discontinued determines when an executing program and start another. Multiple processes or threads reading is a term that in NT, refers to the wires that serve as implementing partners.Having multiple execution threads within a process, means that a process executes, simultaneously, different parts of a program on different processors.
Symmetric multiprocessing allows system and application requirements are distributed evenly among all available processors, making everything run much faster. Windows NT uses the NT File System (NTFS). This file system supports file names up to 256 characters. It also allows tracking of transactions. This means that if the system fails, NT returns the data to the state immediately before the crash. Microsoft designed Windows NT to make it portable. It consists of a kernel or nucleus, as well as various sub-systems. There subsystems available for applications that run programs based on OS / 2 and POSIX. A virtual DOS processor (DSP) running MS-DOS and Windows 16-bit applications. NT networking software includes point to point for NT users can share files with other users and applications running NT or Windows for Workgroups.
Windows NT NT security requires users to enter a password each time you start the operating system, whether or not connected to a servidor.Cada NT once it starts, it requests a password. NT government certification qualify for C-2 for safe environments. Microsoft has stated that in the future will offer enhancements that will increase the security level of NT and make it even more attractive to government agencies. A security feature is the NT User Manager. This program ensures that passwords be subject to company policy. It also allows each NT machine is configured to a number of users, giving each its own privilege level. It is also possible to create groups and give the same privileges to all members of a group. Another key safety feature is the event viewer. This program allows network administrators to view a log of all errors and breaches to the network, including time, date and type of violation, and the place where the event occurred and the name of the user involved. Implementation of NT with other network operating systems Windows NT Server provides integrated file sharing, printer sharing capabilities for workgroup computing and network interface open system, which includes integrated support for IPX / SPX, TCP / IP, NetBEUI and other transport.
NT Server is compatible with existing networks such as VINES, NetWare, UNIX, LAN Manager 2.x and Windows for Workgroups. Windows NT includes application programming interfaces (APIs) that allow manufacturers to network operating systems (NOS) write client software to enable their products to run with it. NT supports Macintosh clients and treats them the same way as users of the network, supporting the AppleTalk File Protocol.Macintosh users can access the server NT Server as if it were an AppleShare server. Windows NT Server 4.0 Integration of the user interface of Windows 95 NT 4.0, provides a consistent view across the desktop and the server, resulting in less training time and a faster development of the new network operating system. Tools such as Task Manager, and Network Monitor simplifies server administration.
The task manager offers extensive application and indications of CPU and graphics memory, which allows administrators to control system behavior.Network Monitor has the ability to monitor network traffic, allowing prevent performance problems with it. The directory service of Windows NT (NTDS) holds up to 25,000 users per domain, and hundreds or thousands per company. No matter how centralized or decentralized business, NTDS directory allows you to install an organization capable of providing a complete management of resources, services and applications. NTDS is a directory service that provides security, reliable architecture, graphical interface for management and open interoperability with Novell NetWare. NT 4.0 includes a diagnostic program that provides information about the drivers and the use of the network, minimizing the possible system errors.
This information is presented in graphical form that can be used from a remote NT system. The performance and scalability of the server have been improved as well as sharing and printing of files and performance of Internet server. Windows NT 4.0 works with systems such as NetWare, UNIX and IBM. It supports more than 5,000 hardware platforms and is compatible for most common network protocols such as TCP / IP, IPX / SPX, NetBEUI, AppleTalk, data link control (Data Link Control DLC), HTTP, network architecture systems (Systems Network Architecture, SNA), PPP and point to point protocol tunneling through (Point to Point Tunneling Protocol, PPTP). NT 4.0 is supported for a variety of client systems as Windows 3.x, Windows 95, Windows NT Workstation, IBM OS / 2 and Macintosh.
