AC’97 (Audio Codec '97). AC '97 is the next step in enabling PCs with
audio quality comparable to consumer electronics devices. The
specification defines new cost-effective options to help integrate the
components necessary to support next-generation auto-intensive PC
applications such as DVD, 3-D multiplayer gaming and interactive music.
The specification also defines new extensions supporting modem and
docking to help both desktop and mobile manufacturers adopt these new
technologies more quickly and cost-effectively. This specification uses
software emulation to compete with the PCI SoundBlaster specification.
ACPI (Advanced Configuration and Power Interface). The ACPI
specification defines a cross-platform interface designed to support many
operating systems. ACPI defines a flexible and abstract hardware interface
that provides a standard way to integrate power management features in a
PC system, including hardware, operating system and application
software. This enables the system to automatically turn ON and OFF
peripherals such as CD-ROMs, network cards, hard disk drives, and
printers, as well as consumer devices connected to the PC such as VCRs,
TVs, phones, and stereos. With this technology, peripherals are also able
to activate the PC. For example, inserting a tape into a VCR can turn on
the PC, which could then activate a large-screen TV and high-fidelity
sound system.
AGP (Accelerated Graphics Port). An interface specification that enables
high-performance 3D graphics on mainstream PCs. AGP was designed to
offer the necessary bandwidth and latency to perform texture mapping
directly from system memory.

Backup. A copy of a file, directory, or volume on a separate storage device
from the original. This copy is for the purpose of data retrieval in case the
original is accidentally erased, damaged, or destroyed.
