Digital Display Working Group (DDWG) The Digital Display Working Group (DDWG) was a group whose purpose was to define and maintain the Digital Visual Interface standard. It was organized by Intel, Silicon Image, Compaq, Fujitsu, HP, IBM and NEC. It developed the Digital Visual Interface (DVI) standard in 1999.[1] It currently appears to be defunct as its domain is now being used by a cybe..

USB OTG (USB On-The-Go) An enhancement to the Universal Serial Bus (USB) that enables portable devices to be cabled directly together (no computer required). OTG devices operate in “dual-role” mode and can be identified as either a host or a peripheral. When cabled to each other, an automatic negotiation makes one the host and the ..
ampere An ampere is a unit of measure of the rate of electron flow or current in an electrical conductor. One ampere of current represents one coulomb of electrical charge (6.24 x 1018 charge carriers) moving past a specific point in one second. Physicists consider current to flow from relatively positive points to relatively negative points; this is called conventional ..
ohm The ohm is the standard unit of electrical resistance in the International System of Units ( SI ). Ohms are also used, when multiplied by imaginary numbers, to denote reactance in alternating-current ( AC ) and radio-frequency ( RF ) applications. Reduced to base SI units, one ohm is the equivalent of one kilogram meter squared per second cubed per ampere squared (1 kg ..
volt The volt (symbolized V) is the Standard International (SI) unit of electric potential or electromotive force. A potential of one volt appears across a resistance of one ohm when a current of one ampere flows through that resistance. Reduced to SI base units, 1 V = 1 kg times m2 times s-3 times A-1 (kilogram meter squared per second cubed per ampere). Voltage can ..
Voltage sag From Wikipedia, the free encyclopedia Jump to navigationJump to search A voltage sag (U.S. English) or voltage dip[1] (British English) is a short duration reduction in rms voltage which can be caused by a short circuit, overload or starting of electric motors.[2] A voltage sag happens when the rms voltage decreases between 10 and 90 percent of nominal voltage for one-half cycle to one ..
Data center From Wikipedia, the free encyclopedia Jump to navigationJump to search An operation engineer overseeing a network operations control room of a data center A data center (American English [1]) or data centre (British English)[2][3] is a building, dedicated space within a building, or a group of buildings[4] used to house computer systems and associated components, such as telecommunications and storage systems.[5][6] Since IT operations are crucial for business continuity, ..

Intel QuickPath Interconnect The Intel QuickPath Interconnect (QPI) is a point-to-point processor interconnect developed by Intel which replaced the front-side bus (FSB) in Xeon, Itanium, and certain desktop platforms starting in 2008. It increased the scalability and available bandwidth. Prior to the name’s announcement, Intel referred to it as Common System Interface (CSI). Earlier incarnations were known as Yet Another Protocol (YAP) and YAP+. QPI 1.1 is a significantly revamped ..
Mac OS Definition This is the operating system that runs on Macintosh computers. It is pronounced, “mack-oh-es.” The Mac OS has been around since the first Macintosh was introduced in 1984. Since then, it has been continually updated and many new features have been added to it. Each major OS release is signified by a ..
