802.11b - A wireless standard for device connectivity. Mainly for LAN connections and not necessarily wireless Internet . This standard allows handhelds, desktops and other wireless devices to exchange information at up to 11 mbs at several hundred feet.
Aspect ratio - The ratio of screen width to screen height. For TVs it is either 4:3 (1.33:1) or 16:9 (1.78:1). Theater film uses many different aspect ratios, some as high as 2.5:1.
Auto Reverse - This feature will automatically reverse the direction of the tape at the end of each side of the cassette for extended listening. Some decks have this feature in both record and play modes, others in play mode only.
Baud Rate - Used interchangeably with "Bits Per Second." The unit of measure used to rate the speed at which computer data can be translated via modem. Typical modem rates are 2,400, 9,600, 14,400, and 28,000 baud.
EXE - A Microsoft Windows file extension used for applications that are "executable," and immediately launch a program when opened.
Equalizer - A component or circuitry within a component that divides audio frequencies into separate bands, allowing the user to change the volume of each band and adjust for differences in listening space acoustics, personal taste or the characteristics of a specific recording.
Frequency (audio) - Frequency, in music, refers to the pitch of a sound. The frequency of a sound is measured in cycles per second. One cycle is one complete audio waveform. Bass frequencies have a lower number of waveforms per second. Treble frequencies have a very high number of waveforms per second.
HSB (Hue, Saturation, and Brightness) - A color model that utilizes Hue, Saturation, and Brightness as the three coordinates.
Optical Zoom - Enlarges or magnifies images optically, using a lens system to allow zoom from 8x, 10x or 12x.
Radial Faceplate CRT - With the radial faceplate CRT (Cathode Ray Tube), the radial faceplate picture tubes combined with a short-throw lens system permits the depth of certain projection TV cabinets to be reduced. The CRT's curved faceplate focuses the light beam in the centre of the lenses, where focusing is most accurate.
