1394. 1394 is the IEEE designation for a high performance serial bus that
offers data transfers at 100/200/400 Mbps. This serial bus defines both a
back plane physical layer and a point-to-point cable-connected virtual bus.
The primary application of the cable version is the integration of I/O
connectivity at the back panel of personal computers using a low-cost,
scalable, high-speed serial interface. The 1394 standard also provides
new services such as live connect/disconnect capability for external
devices including disk drives, printers and hand-held peripherals such as
scanners and cameras. This is a new standard to complement the slower
USB interface and to compete with the more expensive SCSI interface.
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.
