1394

1394 is the IEEE designation for the high performance serial bus at 12.5, 25 or

50MBytes/sec speeds. 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 ver-

sion 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 pro-

vides new services such as live connect/disconnect capability for external devices

including disk drives, printers and hand-held peripherals such as scanners and cam-

eras. This is a new standard to complement the slower USB interface and to compete

with the more expensive SCSI interface.

AC97 (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 in-

tegrate the components necessary to support next-generation auto-intensive PC ap-

plications such as DVD, 3-D multiplayer gaming and interactive music. The speci-

fication 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 pro-

vides a standard way to integrate power management features throughout a PC sys-

tem, including hardware, operating system and application software. This enables

the system to automatically turn ON and OFF peripherals such as CD-ROMs, net-

work 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

will also be 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.

Bus Bus Frequency Bandwidth Data Transfer Rate

PCI 33MHz 33MHz 133MByte/sec

AGP 1X 66MHz 66MHz 266MByte/sec

AGP 2X 66MHz 133MHz 512MByte/sec

AGP 4X 66MHz 266MHz 1024MByte/sec

BIOS (Basic Input/Output System)

BIOS is a set of routines that affect how the computer transfers data between com-

puter components, such as memory, disks, and the display adapter. The BIOS in-

structions are built into the computer’s read-only memory. BIOS parameters can be

configured by the user through the BIOS Setup program. The BIOS can be updated

using the provided utility to copy a new BIOS file into the EEPROM.

Bit (Binary Digit)

Represents the smallest unit of data used by the computer. A bit can have one of two

values: 0 or 1.
