Glossary
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.
