DMA (direct memory access)

A transfer mode between the main memory and the peripheral devices

that without passing through the CPU.  Using the DMA controller, data

is transferred much faster.

DRAM (Dynamic RAM)

A most common type of computer memory.  It usually uses one transistor

and a capacitor to represent a bit.  As the development of technology, the

memory type and specification used in computer becomes variety, such

as SDRAM, DDR SDRAM, and RDRAM.  For further instruction, please

see the table below:

ECC Memory (error correcting code memory)

A type of memory that contains special circuitry for testing the accuracy

of data and correcting the errors on the fly.

IDE (Integrated Drive Electronics)

A type of disk-drive interface widely used to connect hard disks, CD-

ROMs and tape drives to a PC, in which the controller electronics is

integrated into the drive itself, eliminating the need for a separate adapter

card.  The IDE interface is known as the ATA (AT Attachment)

specification.
