Access Modifier - - ANS - -A keyword defining the visibility of a method or field in a
class.
Digitizer Tablet / Digitizer / Graphics Tablet - - ANS - -A tool used to convert hand-
drawn images into a format suitable for computer
processing. Images are usually drawn onto a flat surface with a stylus and
then appear on a computer monitor or screen.
Accessor - - ANS - -A typed method (function) that returns the value of a private field
in an object.
ADSL
Asynchronous Digital Subscriber Line. - - ANS - -Used by homes and businesses for
dedicated digital high
speed connection to the internet over conventional phone lines.
Attenuation - - ANS - -the reduction in signal strength while transmitting data. The
further the signal
,gets from the source the weaker it will become
Attribute - - ANS - -Fields or property of a class defining the data associated with
each object.
BIOS - - ANS - -the essential start up instructions of a computer, stored in ROM on
the motherboard.

that stores the various user configurable computer startup settings that can be
updated or
changed
A type of memory where the BIOS settings are saved
Compiler vs Interpreter - - ANS - -A program that translates an entire high level
program source code into object code. The object
