take ownership

Each file on an NTFS drive has an 'owner'-a user account or group that is given complete access to that file. Taking ownership is the process of becoming the owner of a resource.

telecommuter

Someone who remotely connects to his or her office to work from home or a remote location.

Terminal Services

Whereas normal servers provide file or printer access, a terminal server provides full desktop access. Terminal Services allow a single machine to be used by multiple users at once. Each individual uses their own keyboard, mouse, and monitor, and is presented with a Windows Desktop, but all programs run locally on the terminal server.

termination

The use of a terminator at both ends of a SCSI daisy chain to keep data signals from bouncing back on the SCSI bus after they reach the end. The terminator is a small plastic connector that has a resistor (ceramic-based material that absorbs electricity) inside it.

throughput

The amount of data that can be transferred in a set period of time.

Token Ring

A Data-Link layer protocol developed by IBM that uses a token-passing method for transmitting data. Each device on the ring takes turns using the token. The token can be used by only one device at a time.

transistor

A microscopic electronic device that uses positive electrons to create the binary value of one, or 'on,' and negative electrons to create the binary value of zero, or 'off.' Modern CPUs have millions of transistors.

transitive

Trusts that are transitive allow a domain to act as an intermediary for two other domains. If A trusts B, and B trusts C, there is a physical path between A and C. Even with that physical link, though, directory information will pass from A to C only if B acts as a transitive link.

trust

A trust is configured to allow two Windows domains to share user authentication information and to allow users from one domain to access resources in another domain.

unshielded twisted-pair (UTP)

A type of media that can contain four, six, or eight wires. Pairs of wires are twisted together to prevent signal interference. The wires are then wrapped in a plastic cover. UTP is identified by the category nomenclature.

Upper Memory Area (UMA)

The area of memory between 640KB and 1MB in an IBM-compatible computer. This area of memory was originally reserved for system and video use.

USB hub

A connectivity device that provides multiple USB connections so that several USB devices can communicate with the computer.

Users folder

One of a number of default folders in the Active Directory. In most cases, using this default location is fine. Users in this folder can later be placed into groups in other folders or organizational units.

Virtual Address Extension (VAX)

The technology built by DEC to run the VMS platform computers.

virtual circuit

A logical connection between two devices that transmits and receives data.

virtual private networking (VPN)

Using encrypted envelopes to securely transmit sensitive data between two points over the unsecured Internet.

virtual RAM

A function of the operating system that is used to simulate RAM by breaking computer programs into small units of data called pages and storing the pages in a page file on the hard disk.

volume

A part of a physical disk that is identified by a single drive label.

wide area network (WAN)

A relatively low-speed data connection (typically 1.546 Mbps) that uses the telephone company to connect two locations separated by a large geographical area.

Windows Internet Naming Service (WINS)

A Microsoft proprietary protocol that runs on a Windows NT/2000 server or Windows Server 2003. The protocol is used on Windows servers to resolve NetBIOS names, the workstation name on Windows computers, to IP addresses. WINS is similar in concept to DNS.

Windows Internet Naming Service (WINS) server

Maps the NetBIOS names that NT uses to identify computers with an IP address.

Windows NT Diagnostic

A utility in Windows NT 3.51 and 4 that displays system configuration information in a graphical format. System settings can be changed and informative reports generated from this utility.

Windows operating system

An operating system developed by Microsoft that provides a graphical user interface (GUI) for DOS.

Windows Update

A set of online updates and drivers provided by Microsoft that allow users to locate current files for their system, and for new devices.

wizard

A configuration assistant that walks the user through a short series of guided steps to complete a task.

workstation

Another name for a computer that is used by users. It is sometimes used to describe powerful computers that are used for completing complex mathematical, engineering, and animation tasks.
