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.
IEEE 1394
A new, high speed external bus standard, also known as FireWire or iLink ,
which supports data transfer rates of up to 400 Mbps for connecting up to 63
external devices.
IrDA (Infrared Data Association)
A group of device vendors, including computer, component and
telecommunications, who have developed a standard for transmitting data via
infrared light waves. This enables you to transfer data from one device to
another without any cables.
LAN (local area network)
A computer netwoek that covers a relatively smaller area, such as in a building
