The following terms may appear in this User’s Guide.
Aactive-matrix display—A liquid crystal display (LCD) made 
from an array of liquid crystal cells using active-matrix 
technology. Also known as a “TFT display,” in its simplest 
form there is one thin film transistor (TFT) for each cell. This 
type of display works well with computers because of its 
shallow depth and high-quality color. Active-matrix displays 
are viewable from wider angles than most passive-matrix 
displays.
adapter—A device that provides a compatible connection 
between two units. For example, the computer’s internal 
display adapter receives information from the software and 
translates it into images on the screen. An adapter can take 
a number of forms, from a microprocessor to a simple 
connector. An intelligent adapter (one that is capable of 
doing some processing) may also be called a controller.
Alternating Current (AC)—The type of power usually 
supplied to residential and commercial wall outlets. AC 
reverses its direction at regular intervals. Compare 
Direct 
Current (DC)
.
application—A computer program that you use to perform 
tasks of a specific type. Applications include word 
processors, spreadsheets, and database management 
systems. See also 
program.
