Glossary of Terms- Here I have listed some common terms used with-in this web and the internet.

AC-3- An audio standard developed by Dolby Laboratories for delivering 5.1 audio (front left, front center, front right, back left, back right, low-frequency enhance). This system compresses six channels of digital audio into 384 Kbps rather than 4 Mbps uncompressed.

ACPI- Advanced Configuration and Power Interface. An abstract interface that defines a power management and configuration mechanism for hardware and operating systems. Part of the industry-wide OnNow Initiative, ACPI is defined in the industry-sponsored ACPI Specification.

AGP- Accelerated Graphics Port. An interconnect between high-performance, 3-D graphics components. The interconnect is based on a set of performance extensions or enhancements to PCI.

APIC- Advanced Programmable Interrupt Controller.

Asynchronous- An operation that proceeds independently of any timing mechanism such as a clock. Compare with synchronous.

A.T.A- AT Attachment. Also known as IDE. ATA defines the physical, electrical, transport, and command protocols for the internal attachment of storage devices.

BIOS- Basic Input Output System. A set of routines in firmware to support the transfer of information between elements of the computer such as memory, disks, and the monitor.

BUS- A system bus that is connected directly to the microprocessor on a system board. Informally, the term refers to system-board buses that are located closer to the microprocessor than ordinary expansion buses (that is, with less buffering).

CMOS- Complementary Metal-Oxide Semiconductor. A chip that stores information about the hardware on a computer.

Cache- A memory subsystem for storing copies of data values that are used frequently, so the data can be retrieved for quick access.

CD- Compact Disc

CD-R- Compact Disc Recordable

CD-ROM- A drive that reads Compact Disc

CD-RW- Compact Disc Re-Writeable / Writer

CPU- Central Processing Unit

DDR- Double Data-rate System Memory

DMA- Direct Memory Access.

DOS- Disk operating system

DVD- Digital Video Disc

DVD-RW- Digital Video Disc Re-Writable / Writer

DVD-ROM- A drive that reads Digital Video Disc

EEPROM- Electrically erasable programmable ROM. (also- EPROM)

Format- Refers to the second process of preparing for a Operating System installation

FID- Frequency Identifier

FSB- Front Side Bus

Flash- A type of non-volatile memory built into the unit or available as a PC Card. You can write flash memory in blocks or over the entire chip. This ability facilitates erasing or updating.

GUI- Graphical User Interface

HD- Hard Drive

HDD- Hard Disc Drive (same as the above HD)

HSF.- Heat Sink Fan

HS- Heat Sink

ID- Identification

IDE- Integrated Device Electronics. A type of disk-drive interface where the controller electronics reside on the drive. This eliminates the requirement for a separate adapter. See also ATA.

I/O- Input/output.

IRQ- Interrupt request. A device can use IRQ to request service from its software driver

LED- Light Emitting Diode

MoBo- Motherboard

Motherboard- The main component of a PC sub-system-  see System Board

OEM- Original equipment manufacturer

OPN- Operational Part Number

O/S- Operating system

Partition- The areas located on a Hard Disc Drive used for data storage

PGA- Pin Grid Array

PN- Part Number

PSU- Power Supply Unit

RAID- Redundant Array of Independent Disks.

Registry- A database containing configuration and control data for the operating system. This information includes which file systems and drivers to load at computer system boot. The Configuration Manager exports system services to manipulate registry key objects that are contained in the database

SCSI- Small computer system interface (pronounced "scuzzy"). An I/O bus based on the ANSI SCSI-II standard, designed as a method for connecting several classes of peripherals to a host system. This design does not require modifications to generic hardware and software.

SATA- Serial ATA

S/PDIF- Sony/Phillips Digital Interface Format. A standard for digital connection of consumer audio devices

System Board- The primary circuit board in a computer system that contains most of the basic components of the system. Also motherboard or planar.

Synchronous- Any operation that proceeds under control of a clock or timing mechanism. Compare with asynchronous.

U.S.B.- Universal Serial Bus

V- Volts

VGA- A display adapter setting for 640x480-pixels color resolution.

WHQL- Windows Hardware Quality Labs. Formerly Microsoft Compatibility Labs. WHQL provides compatibility testing services to test hardware and drivers for Windows operating systems. WHQL administers testing for the "Designed for Microsoft Windows" logo programs.

Windows- A graphical User Interface Program  (Brand)

Ziff- Refers to a Ziff Socket- The socket the CPU installs to
