AGP – Accelerated Graphics Port (strictly for video cards)

ATA – Advanced Technology Attachment

BIOS – Basic Input / Output System (on bootup you can access it usually with the “del” key or F10 key)

CACHE – A special high-speed storage mechanism. It can be either a reserved section of main memory or an independent high-speed storage device. Two types of caching are commonly used in personal computers: memory caching and disk caching.

cBO – The stepping of P3 that failed to reach 1Ghz

cCO – The embarrasment of the decade when Intel had to remove it’s 1.13Ghz chips from the market place as they weren’t fit for the speed.

COLD BOOT – The reboot of a computer by electrical switch. (actually shutting off the power).

CPU – Central Processing Unit (main processor for your system)

DIMM – Dual Inline Memory Module.

EB – Denotes a Coppermine processor running on a 133Mhz bus. E meant coppermine and B meant Bus!

ECC Error – Correcting Code memory, a type of memory that includes special circuitry for testing the accuracy of data as it passes in and out of memory.

FC – Flip Chip.

FCPGA – Flip Chip Pin Grid Array. Intel named it the “flip chip” because because the chip is upside down on the socket compared to earlier chips.

FSB – Front Side Bus.

FPS (not the games) Floating Point Scheduler.

FPS (the games) Frames per second.

FPS (also the Games) – First Person Shooter.

FPU – Floating Point Unit a specially designed chip that performs floating-point calculations. Computers equipped with an FPU perform certain types of applications much faster than computers that lack one. In particular, graphics applications are faster with an FPU.

GHZ Gigahertz = 1000 Megahertz.

GPU – Graphical Processing Unit (processor on your video card)

HD – Hard Drive.

HSF – Heat Sink & Fan.

ISA – Industry Standard Architechture (old school and runs at 1/2 the speed of PCI).

LNK = Lovely New Kit – New hardware that enhances a user’s computer, life and brag factor!

MHZ – MegaHertz.

MOBO – Motherboard.

MTBF = Mean Time Before Failure – The average time (in hours usually) you can expect a hard-disk/Cd-Rom drive to work before it dies.

OEM – Original Equipment Manufacturer destined – a chip or component is OEM when it doesn’t come in fancy retail packaging and is usually in a white box. Usually cheaper as a consequence. These articles aren’t meant for retail sale – but they end up there.

OS – Operating System.

PARITY – Comparing data for odd or even numbers. Used for error correction.

PCI – Peripheral Component Interface.

PSU or PS – Power Supply Unit.

PS2 – Not a Playstation2 – but relates to a range of IBM PCs from the early nineties that used their own kind of connectors instead of AT type connectors for keyboards and serial connectors for mice.

PPGA – Plastic Pin Grid Array.

RAID – Redundant Array of Inexpensive Disks (system to use several disk to secure against data loss and speed data access).

Retail – This is the fancy box and full mfg warranty. Intel chips have a 3 year warranty where OEM is anywhere from a week to a year.

SCSI – Small Computer System Interface. Much faster and more expensive. Replaces IDE but usually is only commercially used.

SIMM – Single Inline Memory Module.

Soft Boot – To force a reboot of the computer by software command – this may be by Ctrl+Alt+Del or by a command or simply Start….Shutdown….Restart. Rebooting w/o actually shutting down power to the system.

Socket 370 – The Intel socket that originated as home for the Celeron PGA and is now home for coppermine celerons and P3’s. Will soon become home to Tualatin.

Socket A – The socket of the Duron, Thunderbird and soon the Morgan, Palamino and Mustang.

Slocket – An adapter to enable the use of socket 370 PPGA or FCPGA chips in a slot 1 motherboard environment.

Slot 1 – A 242pin slot adapter for Celerons, Pentium 2’s and 3’s.

Socket 7 – A 321 pin socket that formed the home of chips from Pentium classics, Cyrix UDMA – Ultra Direct Memory Access
6×86 chips, Winchips and AMD K6 series chips. Now obsoleted officially.

Vcore – Core Voltage of the CPU.

USB – Universal Serial Bus.
