Accounts Manager (SAM)
The database in which the local user account, password, and permissions information is stored on a Windows 2000 computer.
Active Directory also refers to the Windows implementation of a directory service. Active Directory stores information about a variety of objects in the network.
Importantly, user accounts, computer accounts, groups, and all related credential information used by the Windows implementation of Kerberos are stored in Active Directory.
Active Directory first became available as part of Windows 2000 and is available as part of Windows 2000 Server products, Windows Server 2003 products, Windows Server 2008 products, and Windows Server 2008 R2 products. Active Directory is not present in Windows NT 4.0 or in Windows XP.
Active Directory
The database in which the domain user account, password and permissions information (in addition to information about resources and other objects) is stored on a Windows 2000 domain controller.

Bluetooth is an industrial specification for wireless personal area networks (PANs). Bluetooth provides a way to connect and exchange information between devices like personal digital assistants (PDAs), mobile phones, laptops, PCs, printers and digital cameras via a secure, low-cost, globally available short range radio frequency.
Cache
An area of memory that is used to store frequently needed or recently accessed data. Instead of a slower retrieval of data from the data's actual location, such as a hard disk, cached data can be retrieved more quickly from the cache instead.
Chkdsk

Domain Name System (DNS) Server service
Provides Domain Name System name services for a network by answering DNS queries from DNS clients. It is often referred to as simply the DNS Server.
Driver signing
Operating system drivers and application drivers are used to communicate with hardware components on computers. Microsoft certifies a driver's reliability by driver signing. A digital signature indicates that Microsoft has successfully tested a driver for stability.
Encrypting File System
The Encrypting File System (EFS) provides a method of encrypting information on a local hard disk. The EFS uses a symmetric encryption algorithm to protect files on a local hard disk. Only the user that encrypted the file can access its contents.

A type of IEEE LAN protocol that specifies an implementation of the physical layer and the MAC sublayer of the data link layer. IEEE 802.3 uses CSMA/CD access at a variety of speeds over a variety of physical media. Extensions to the IEEE 802.3 standard specify implementations for Fast Ethernet. Physical variations of the original IEEE 802.3 specification include 10Base2, 10Base5, 10BaseF, 10BaseT, and 10Broad36. Physical variations for Fast Ethernet include 100BaseTX and 100BaseFX
Ethernet II
A type of Ethernet Frame header. Ethernet II is the most frequently used Ethernet Frame type in use on TCP/IP networks.
Fiber Distributed Data Interface (FDDI)
FDDI is a 100 Mbit/s ANSI standard local area network architecture. FDDI is typically based on optical fibre (though it can be copper cable, in which case it may be called CDDI).
File allocated table (FAT)
A file system based on the file allocation table structure maintained by some operating systems. FAT keeps track of the status of various segments of disk space for file storage. Windows 2000 supports two versions of FAT: FAT16 (compatible with MS-DOS, Windows 3.x, Windows 95/98, NT, Linux, OS/2 and others) and FAT32 (compatible with Windows 95b and Windows 98).
File system
A file system implements a particular set of naming and organization conventions for the storage and retrieval of files.
Foreign Keys
Foreign Keys represents the 'Nuts and Bolts' of relating data across tables.
Gateway (and Client) Service for Netware
Gateway (and Client) Services for NetWare (GSNW) allows Microsoft client computers to access NetWare resources through a software gateway. GSNW is a protocol translation gateway, allowing Microsoft Network Clients to access shared resources on NetWare computers.

Hardware Compatibility List (HCL)
A list of hardware components that have been tested by Microsoft for compatibility with Windows 2000. The HCL is available on Microsoft's website.
Hardware profile
A hardware profile is a collection of registry settings that you can use to change hardware settings easily. The most common application of hardware profiles simplifies readying a laptop for use on or off a network. After defining two hardware profiles, one for use on the network and one for use off the network, users can ready their laptop for either situation by simply choosing the appropriate hardware profile. Hardware profiles allow you to save time by saving sets of hardware configurations.
Hot-swappable
The ability to add or remove disks, or other devices, by simply adding them or removing them physically without having to restart the computer.
Inf file
An Inf file defines parameters for installation sequences, typically the installation of operating system driver files. An Inf file can be right-clicked and the driver installed via the context menu.
Institute of Electrical and Electronics Engineers, Inc. (IEEE)
The IEEE 754 standard is the standard for implementing floating-point numbers and floating-point arithmetic
Internetwork
An internetwork is a collection of separate networks. Typically, the term describes networks that are separated by routers and therefore contain multiple logical segments.
IPX/SPX
IPX/SPX is a communications protocol used in a Novell network.
Logical Unit Number (LUN)
A LUN is a number that defines a hardware device that usually exists on a chain with other hardware devices. For example, SCSI devices can be chained with up to 15 devices on a single chain. Each device on the chain is assigned a LUN in order to differentiate each one.
MSI file
MSI files are Windows Installer Package files, supplied by the software vendor to facilitate the installation of an application. MSI files are also used in Group Policy software deployment.
NetBEUI
Acronym for NetBIOS Extended User Interface. NetBEUI is a non-routable transport protocol that represents an extension of the initial NetBIOS transport protocol specifications. Since NetBEUI is not routable, its usefulness is limited to small, single segment networks.
Network segment
A network segments is a group of computers within the same Ethernet Broadcast Domain, including all computers on the same side of a particular router interface.
NTFS file system
An advanced file system used in Windows 2000. NTFS supports file system recovery, large storage media, long file names, and other features of the POSIX subsystem. NTFS also supports object-oriented applications by treating all files as objects with user-defined and system-defined attributes.
NWLink IpX/SPX/NetBIOS Compatible Transport Protocol

PCI slots
A PCI Slot is a plug on the computer's motherboard that supports PCI peripheral cards.
Plug and Play
Plug and Play automates the installation of new hardware. The operating system automatically configures the required resources for a new computer peripheral. Examples of Plug and Play compliant operating systems include Windows 95, Windows 98 and Windows 2000.
Registry
A repository of application and system configuration information.
SCSI port
A standard high-speed parallel interface defined by the American National Standards Institute (ANSI). A SCSI interface is used for connecting computers to peripheral devices, such as hard disks and printers, and to other computers and local area networks (LANs). SCSI (pronounced scuzzy) is short for Small Computer System Interface.

SysVol Folder
The SysVol folder contains the registry information and domain related information, such as the Active Directory structure information.
The Dynamic Host Configuration Protocol (DHCP) Server service
DHCP is a client/server protocol that allows automatic assignment of IP addressing information to DHCP clients through the following process. First, DHCP clients request IP addressing information from a DHCP Server. (The DHCP Server contains groups of IP addresses known as scopes.) Finally, IP addresses are selected from one of the scopes on a particular DHCP server.
Token Ring 802.5
An IEEE LAN protocol that specifies an implementation of the physical layer and MAC sublayer of the data link layer. IEEE 802.5 uses token passing access at 4 or 16 Mbps over STP or UTP cabling. Token Ring 802.5 is functionally and operationally equivalent to the IBM Token Ring
