ACPI
(Advanced Configuration and Power Interface) is a power management
specification that allows the operating system to control the amount of power
distributed to the computer's devices. Devices not in use can be turned off,
reducing unnecessary power expenditure.
AGP
(Accelerated Graphics Port) is a PCI-based interface which was de-
signed specifically for demands of 3D graphics applications. The 32-bit AGP
channel directly links the graphics controller to the main memory. While the
channel runs at only 66MHz, it supports data transmission during both the
rising and falling ends of the clock cycle, yielding an effective speed of
133MHz.
AT
The was the original form factor of IBM's PC.
ATAPI
(AT Attachment Packet Interface), also known as IDE or ATA, is a
drive implementation that includes the disk controller on the device itself. It
allows CD-ROMs and tape drives to be configured as master or slave devices,
just like hard drives.
ATX
The form factor was designed to replace the AT form factor. It improves
on the AT design by rotating the board ninety degrees, so that the IDE
