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 computers devices. Devices not in use can be turned off,
reducing unnecessary power expenditure.
AGP (Accelerated Graphics Port) is a PCI-based interface which was designed
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 was the original form factor of IBMs PC.
ATAPI (AT A ttachment 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.
AT X 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 connectors
are closer to the drive bays, and the CPU is closer to the power supply and
cooling fan. The keyboard, mouse, serial, USB, and parallel ports are built in.
Bandwidth refers to carrying capacity. The greater the bandwidth, the more
