Microsoft has replaced Windows 2000 Server products with Windows Server 2003, and Windows 2000 Professional with Windows XP Professional.
Windows 2000 has the reputation of being the most stable of the Microsoft operating systems after Windows NT 3.51.
All versions of Windows 2000 share certain features.
Version 3 of the NTFS, (also known as version 5.0), introduced quotas, file-system-level encryption (called EFS), sparse streams and reparse points, which are used to implement Directory Junctions, Volume Mount Points, Hierarchical Storage Management, Native Structured Storage and Single Instance Storage. By adding these features, Windows could compete with established file serving systems like Netware and UnixUNIX (or Unix is a portable, multi-task and multi-user computer operating system originally developed by a group of AT&T Bell Labs employees including Ken Thompson, Dennis Ritchie and Douglas McIlroy. Unices The term Unices includes Unix and Unix-like ope.
The Encrypting File SystemThis is about the Microsoft Windows file system, for the old IRIX file system, see EFS (IRIX). The EFS or Encrypted File System is a file system available in Microsoft's Windows 2000, Windows XP, and Windows Server 2003 operating systems. The technology a (EFS) introduced strong encryption into the Windows file world. It allowed any folder or drive to be encrypted and was transparent once implemented. As of February 20042004 : January February March April May June July August September October November December Ongoing events Haiti Rebellion Bloody Sunday Inquiry Exploration of Mars: Rovers Bird flu Israeli-Palestinian conflict Same-sex marriage in the United States SCO, its encryption has not been compromised.
Windows 2000 introduced the Windows Driver ModelIn computing, WDM stands for Windows Driver Model . It provides a framework for device drivers that operate under Microsoft Windows 98/ME/2000/XP and Server 2003. WDM is a successor of VxD, which was used on older versions of Windows such as Windows 95 an (WDM) driver model to the NT kernel . WDM is a multilayer driver model used to separate general functionality of devices from the specifics. For example, Microsoft may provide a standard USBNote: USB may also mean upper sideband in radio. Universal Serial Bus USB provides a serial bus standard for connecting devices, usually to a computer, but it also is in use on other devices such as set-top boxes, game consoles and PDAs. Overview A USB sy driver that provides the basic functionality a USB device may use, such as raw bus protocol communication. The hardware vendor then only has to implement a driver that provides the functionality specific for whatever the device does. This can greatly simplify driver programming, and keeps programmers from introducing bugs every time a basic device protocol is reimplemented for a new product. Additionally, WDM drivers are theoretically compatible with any version of Windows supporting WDM (Win98, WinME, WinXP) regardless of the kernel. Drivers are the leading cause of instability in Windows, and WDM addresses this.
