A
adaptor: 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.

symbols, such as punctuation marks or mathematical symbols.
alternating current (AC): Electric current that reverses its direction of flow
at regular intervals.
