ACPI
Advanced Configuration and Power Interface (ACPI) is an OS-directed
configuration, power management, and thermal management interface.
AHCI
Advanced Host Controller Interface (AHCI) is a SATA Host controller
register-level interface.
ATA
The Advanced Technology Attachment (ATA) interface connects storage
devices including hard disks and CD-ROM drives to a computer.
BIOS
The Basic Input/Output System (BIOS) is firmware that is first run when
the computer is turned on and can be configured by the end user
CompactFlash®
CompactFlash® is a solid-state storage device. CompactFlash® devices
use flash memory in a standard size enclosure. Type II is thicker than
Type I, but a Type II slot can support both types.
CMOS
Complimentary metal-oxide-conductor is an integrated circuit used in
chips like static RAM and microprocessors.
COM
COM refers to serial ports. Serial ports offer serial communication to
expansion devices. The serial port on a personal computer is usually a
male DB-9 connector.
DDR
Double Data Rate refers to a data bus transferring data on both the rising
and falling edges of the clock signal.
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.
EIDE
Enhanced IDE (EIDE) is a newer IDE interface standard that has data
transfer rates between 4.0 MBps and 16.6 MBps.
FSB
The Front Side Bus (FSB) is the bi-directional communication channel
between the processor and the Southbridge chipset.
GPIO
General purpose input
