1394

1394 is the IEEE designation for a high performance serial bus tht 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.

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

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 throughout 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 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 Data Transfer Rate

PCI 33MHz 133MByte/sec

AGP 1X 66MHz 266MByte/sec

AGP 2X 66MHz 512MByte/sec

AGP 4x 66MHz 1024MByte/sec

AGP 8X 66MHz 2048MByte/sec

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.

BIOS (Basic Input/Output System)

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

components, such as memory, disks, and the display adapter. The BIOS instructions

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)

A bit is he basic unit of digital data used by the computer. A bit equals either: 0 or 1.
