Boolean Search
.. is a search formed by joining simple terms with AND, OR and NOT. This is done so the user can find exactly what they are looking for without having to scroll through pages of relevant information. The term Boolean comes from the name of the person George Boole, who first Devised the System
RCA
.. or the Radio Corporation of America connector is the most common audio connector. Used for evry sort of analog input and output, these come in colour-coded pairs (usually red for right and black or white for left). They are the cable that connect your TV with your DVD players.
HSCSD
.. or High Speed Circuit Switched Data is a dta communication technology for GSm which boosts data throughput upto 14.4 Kbps in a single channel, and by aggregating channels, upto 57.6 Kbps.
SAR
.. aka Specific Absorption Rate is a measure of the rate at which radio frequency (RF) energy is absorbedby the human body when using a cellular telephone. Studies of SAR and their adverse effects on other living species, however, remains an untouched topic in research.
Ethanol
Ethanol is a alcohol-based alternative fuel produced by fermenting and distilling starch crops such as corn, barley and wheat that have been converted into simple sugars. It is most commonly used to increase Octane and improve the emission quality of Gasoline. its blend with Gasoline is called E85; 85 per cent Ethanol and 15 per cent Gasoline
EDGE
.. is Enhanced Data rates for GSM Evolution. It's technology that gives GSM phones a capacity to handle services for the third generation of mobile telephony. EDGE was developed to enable the transmission of large amounts of data at a high speed - 384 Kilobits per second. It can increase data rates even over existing wireless networks and is also known as ENhanced GPRS or E-GPRS.
JPEG
.. short for Joint Photographic Experts Group, is a lossy image compression technique that reduces files sizes by discarding photo information that the human eye cannot detect. JPG images are best suited for photgraphs. It does not work well on line drawings or simple graphics because there is not a lot of the image that can be thrown out in the lossy process - the image therefore loses clarity and sharpness.
Wardriving
.. is a act of driving in a vehical with a portable computer, an antenna, and wireless LAN adapter to exploit exisiting wireless networks. Set on promiscuous mode, the adapter recieves data packets within its range. "Wardriving" is usually done in a bid to exploit wireless networks for free Internet Access or to illegally access an organisation's data.
GigaByte
A GigaByte contains approximately 1024 MegaBytes or 1,024,741,841 bytes of data. One thousand billion Bytes or approximately 1024 gigaBytes make a TeraByte. In turn, approximately 1024 TeraBytes make a PeraByte. While an ExaByte is approximately 1024 PeraBytes.
Red-Eye
.. in photography is an effect caused by an electronic flashreflecting off the retina making it look red. Cameras with flash located close to the lens suffer the most from this problem. Professional photographers hence hold an external flash unit above and off to the side of the lens to eliminate red-eye. Red-eye can also be dited by using most photo-editing software. In fact many digital cameras come with inbuilt capabilities of reducing Red-eye.
