Data - The numbers that make up a digital file.
Color Temperature - A scale used to refer to the visible energy system of various light sources. The scale uses degrees Kelvin as a measure of the mixture on a scale from red to blue white. Daylight = 5500 Kelvin, a blue-white color. The Tungsten in a light bulb produces about 3200 Kelvin, an orange color.
Resolution - A measure of how closely packed the dots in a bitmapped image are, often expressed in dots per inch (dpi) or lines per inch (lpi). The higher the number, the higher the quality. However, doubling the resolution of an image results in a computer file four times as large, requiring more hard disk space and computer memory to handle the higher quality image. Resolution is also used to describe how close together a computer printer can print dots in an image. Again, the larger the number, the higher the quality. It is important to know the capability of the printer's resolution before scanning an image in order to get enough information to print the best quality.
High-Pass Crossover - A filter, often found in a powered subwoofer, that accepts the full-range audio signal heading for the main speakers. This filter only passes frequencies falling above a predetermined frequency and it attenuates those below. The goal is to prevent the main speakers from reproducing sounds that would be more accurately reproduced by a subwoofer.
Interlaced scan - Historically, TV CRTs are interlaced, while computer CRTs are not. Interlaced means that the electron beam skips every other horizontal line, filling in the missing lines on the next pass. A frame is composed of 2 fields. One field is all of the odd numbered lines, and the other field is all of the even numbered lines.
Computer VGA Input Jacks - Front and back computer jacks. The front input provides a convenient point of hookup for a laptop computer, while the desktop computer occupies the rear input. Switching from front to rear is easily accomplished through the on-screen menu system.
Application - A program, such as a word processor or a spreadsheet, that performs one of the important tasks for which a desktop or handheld computer is used. This term is sometimes use in place of or in conjunction with "software."
