DMA

Direct Memory Access (DMA) enables some peripheral devices to

bypass the system processor and communicate directly with the system

memory.

DIMM

Dual Inline Memory Modules are a type of RAM that offer a 64-bit data

bus and have separate electrical contacts on each side of the module.

DIO

The digital inputs and digital outputs are general control signals that

control the on/off circuit of external devices or TTL devices. Data can be

read or written to the selected address to enable the DIO functions.

EHCI

The Enhanced Host Controller Interface (EHCI) specification is a

register-level interface description for USB 2.0 Host Controllers.

EIDE

Enhanced IDE (EIDE) is a newer IDE interface standard that has data

transfer rates between 4.0 MB/s and 16.6 MB/s.

EIST

Enhanced Intel® SpeedStep Technology (EIST) allows users to modify

the power consumption levels and processor performance through

application software. The application software changes the bus-to-core

frequency ratio and the processor core voltage.

FSB

The Front Side Bus (FSB) is the bi-directional communication channel

between the processor and the Northbridge chipset.

GbE

Gigabit Ethernet (GbE) is an Ethernet version that transfers data at

1.0 Gb/s and complies with the IEEE 802.3-2005 standard.

GPIO

General purpose input

HDD

Hard disk drive (HDD) is a type of magnetic, non-volatile computer

storage device that stores digitally encoded data.

ICH

The Input/Ouput Controll Hub (ICH) is an Intel® Southbridge chipset.

IrDA

Infrared Data Association (IrDA) specify infrared data transmission

protocols used to enable electronic devices to wirelessly communicate

with each other.

L1 Cache

The Level 1 Cache (L1 Cache) is a small memory cache built into the

system processor.

L2 Cache

The Level 2 Cache (L2 Cache) is an external processor memory cache.
