(TCP) Transmission Control Protocol
| set of rules used with the internet protocol to send data in the form of message units over the internet. |
Toolbar
| in the graphical user interface, a toolbar is a horizontal row or vertical column of selectable image "buttons" that give the user a constantly visible reminder of and easy way to select desktop or other application functions.
|
Transponder
top | a wireless communications, monitoring, or control device that picks up and automatically responds to an incoming signal.
|
Unified Messaging
| delivery of various forms of messaging data to a single device. Unified Messaging frequently includes delivery of all or a portion of the following services: phone service, voice mail, Email, calendar, paging and fax messages.
|
| TrackPoint | TrackPoint, also called a pointing stick, is a cursor (or pointer) control device found in IBM ThinkPad notebook computers. The device is sometimes called an eraser pointer because it is roughly the size and shape of a pencil eraser. It has a replaceable red tip (called a nipple) and is located in the middle of the keyboard between the G, H, and B keys. The control buttons are located in front of the keyboard toward the user |
(UPS) Uninterupted Power Supply
| device that allows your computer to keep running for at least a short time when the primary power source is lost.
|
(URL) Uniform Resource Locator
| address of a file accessible on the Internet.
|
| VLAN Hopping | VLAN hopping (virtual local area network hopping) is a method of attacking a network by sending packets to a port that is not normally accessible from a given end system. (A VLAN is a local area network with a definition that maps devices on some other basis than geographic location -- for example, by department, type of user, or primary application.) |
| Virtual Network Adapter | A virtual network adapter is a program (instead of a physical network adapter) that allows a computer to connect to a network. A virtual network adapter can also be used to connect all the computers on a local area network (LAN) to a larger network such as the Internet or a collection of LANs |
(VoIP) Voice Over Internet Protocol | technology that employs the IP protocol by telecommunications vendors and service providers in order to transmit voice messages over standard IP based transmission services. |
| Virtual Commerce | Virtual commerce (sometimes known as vCommerce, v-commerce, or vCom) is a type of application, service, or product feature that helps enterprises implement strategies and design Web sites for e-commerce (the buying and selling of goods and services using the Internet). The term "virtual commerce" is sometimes used as a synonym for e-commerce itself. |
(VPN) Virtual Private Network | private data network that makes use of the public telecommunication infrastructure that maintains privacy. |
| Virtual Routing and Forwarding | Virtual routing and forwarding (VRF) is a technology included in IP (Internet Protocol) network routers that allows multiple instances of a routing table to exist in a router and work simultaneously. This increases functionality by allowing network paths to be segmented without using multiple devices. Because traffic is automatically segregated, VRF also increases network security and can eliminate the need for encryption and authentication. Internet service providers (ISPs) often take advantage of VRF to create separate virtual private networks (VPNs) for customers; thus the technology is also referred to as VPN routing and forwarding |
| Virtual Tape | Virtual tape is an archival storage technology that makes it possible to save data as if it were being stored on tape although it may actually be stored on hard disk or on another storage medium. Benefits of virtual tape systems include better backup and recovery times and lower operating costs. |
Vista top | Vista, formerly code named Longhorn, is the name of the next Microsoft Windows desktop operating system release to follow Windows XP. The second beta test version of the product is expected to be available to Microsoft developers between November 2005 and February 2006, and the final product is scheduled for release in December 2006 |
