|
Complementary Metal-Oxide Semiconductor - A semiconductor fabrication technology using a combination of n- and p-doped semiconductor material to achieve low power dissipation. Any path through a gate through which current can flow includes both n and p type transistors. Only one type is turned on in any stable state so there is no static power dissipation and current only flows when a gate switches in order to charge the parasitic capacitance.

|
User Defined Functions
- or - Universal Disk Format - or - Universal Data Format |
User Defined Function - functions provided by the user of a program or environment, in a context where the usual assumption is that functions are built into the program or environment.
Universal Disk Format - A CD-ROM file system standard that is required for DVD ROMs. UDF is the OSTA's replacement for the ISO 9660 file system used on CD-ROMs, but will be mostly used on DVD. DVD multimedia disks use UDF to contain MPEG audio and video streams. Universal Data Format - A superset of data formats used with GIS, imaging, mapping, and CAD products. You can access data in UDF format instead of converting it from one format to another, with full geographic information preserved. |

UTP
|
Unshielded Twisted Pair
|
Unshielded Twisted Pair - Normal telephone wire (in the USA). It may be used for computer to computer communications, e.g. using a version of Ethernet or localtalk. It is much cheaper than standard "full-spec" Ethernet cable.

UXGA
|
Ultra Extended Graphics Array
|
Ultra Extended Graphics Array - A display mode in which the resolution is 1600 pixels horizontally by 1200 pixels vertically (1600 x 1200). This amounts to a total of 1,920,000 pixels on the screen.
|
|
VESA
|
Video Electronics Standards Association
|
Video Electronics Standards Association - An international standards body for computer graphics founded in 1989 by NEC Home Electronics and eight other video display adapter manufacturers.
|
|
VFAT
|
Virtual File Allocation Table
|
Virtual File Allocation Table - Method to store long file names in the existing FAT file systems without altering their data structures.
|
|
VGA
|
Video Graphics Array
|
Video Graphics Array - A display standard for IBM PCs, with 640 x 480 pixels in 16 colours and a 4:3 aspect ratio.
|
|
VoIP
|
Voice over Internet Protocol
|
Voice over Internet Protocol - Any technology providing voice telephony services over IP, including CODECs, streaming protocols and session control. The major advantage of VoIP is lower cost, by avoiding dedicated voice circuits.
|
|
VPN
|
Virtual Private Network
|
Virtual Private Network - The use of encryption in the lower protocol layers to provide a secure connection through an otherwise insecure network, typically the Internet. VPNs are generally cheaper than real private networks using private lines but rely on having the same encryption system at both ends.
|
|
VRAM
|
Video Random-access Memory
|
Video Random-access Memory - Fast memory designed for storing the image to be displayed on a computer's monitor. VRAM may be built from special memory integrated circuits designed to be accessed sequentially.
|
|
WAN
|
Wide Area Network
|
Wide Area Network - A telecommunication network that covers a broad area (Example: Any network that links across metropolitan, regional, or national boundaries).
|
|
WAP
|
Wireless Application Protocol
|
Wireless Application Protocol - An open international standard for applications that use wireless communication. (Example: Internet access from a mobile phone.)
|
|
WEP
|
Wired Equivalent Privacy
|
Wired Equivalent Privacy - A security algorithm for IEEE 802.11 wireless networks. Intention was to provide data confidentiality comparable to that of a traditional wired network. Recognizable by the key of 10 or 26 hexadecimal digits.
|
|
WIFI
|
Wireless Fidelity
|
Wireless Fidelity - A popular technology that allows an electronic device to exchange data wirelessly (using radio waves) over a computer network, including high-speed Internet connections.
|
|
WINS
|
Windows Internet Name Service
|
Windows Internet Name Service - Software which resolves NetBIOS names to IP addresses.
|
|
WLAN
|
Wireless Local Area Network
|
Wireless Local Area Network - Links two or more devices using some wireless distribution method (typically spread-spectrum or OFDM radio), and usually providing a connection through an access point to the wider internet. This gives users the mobility to move around within a local coverage area and still be connected to the network.
|
|
WPA
|
Wireless Protected Access
|
Wireless Protected Access - A security scheme for wireless networks, developed by the networking industry in response to the shortcomings of Wired Equivalent Privacy (WEP). WPA uses Temporal Key Integrity Protocol (TKIP) encryption and provides built-in authentication, giving security comparable to VPN tunneling with WEP, with the benefit of easier administration and use.

|
WUXGA
|
Wide Ultra Extended Graphics Array
|
Wide Ultra Extended Graphics Array - A display resolution of 1920×1200 pixels (2,304,000 pixels) with a 16:10 screen aspect ratio.
|
|
XGA
|
eXtended Graphics Array
|
eXtended Graphics Array - An IBM display standard introduced in 1990. XGA-2 added 1024×768 support for high color and higher refresh rates, improved performance, and support for 1360×1024 in 16 colors.

|
ZIF
|
Zero Insertion Force
|
Zero Insertion Force - A kind of socket for integrated circuits. A ZIF socket can be opened and closed by means of a lever or screw. When open, there the chip may be placed in the socket without any pressure at all, the socket is then closed, causing its contacts to grip the pins of the chip. Such sockets are used where chips must be inserted and removed frequently, such as in test equipment. They are more expensive and usually take up more space than conventional IC sockets.
