( MULTIPLE CHOICES) |100% CORRECT!!
AC
Alternating Current Correct Answers The delivery of electricity (as from
a wall outlet) in which the flow of electrons reverses periodically and
has alternating positive and negative values.
AC adapter Correct Answers A type of power supply that converts AC
power to voltages needed for a device. Generally used for portable PC
systems and other devices. (They are also commonly called "wall warts"
because of their lumpy shape.)
AGP
Accelerated Graphics Port Correct Answers A local bus designed for
video only, it provides a direct link between the processor and the video
card, giving the video card direct access to main memory.
Accelerometer Correct Answers In a smartphone or tablet, a built-in
component that measures tilt and acceleration of the device.
Acceptable-Use Policy Correct Answers A security policy that defines
what actions can be taken on data and computing resources, including—
but not limited to—storing, accessing, deleting, disseminating, and
sharing of that data through computers and networks. Such policy must

efficient access to the domain controllers from many locations.
Active Matrix Display Correct Answers An LCD technology based on
thin-film transistor (TFT) technology. An ________ display has a
transistor at every pixel, which enables much quicker display changes
than passive matrix displays, and produces a display quality comparable
to a CRT.

organic __________________ display panel that uses a thin-film
transistor (TFT) backing to turn each pixel on or off.
Active Partition Correct Answers A primary partition that is marked for
use by the system during startup. You can only boot Windows operating
systems from an _________.
ASPM
Active State Power Management Correct Answers A standard for PCI
Express that allows incremental reduction of power to individual PCIe
serial links (paths). Windows enables or disables a link based on several
parameters, including the system power plan, PCIe capabilities, and
more.
ACT
, Activity Correct Answers In reference to a NIC or other network device,
a light, usually an LED, that blinks to indicate network activity.
