MS-6738 Micro ATX Mainboard
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.
Internal Cache
Short for Level 1 cache, a memory cache built into the microprocessor. The L1 cache is
also called the primary cache.
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.
IRQ (Interrupt Request Line)
IRQs are hardware lines over which devices can send interrupt signals to the
microprocessor. When you add a new device to a PC, you sometimes need to set its
IRQ number by setting a DIP switch. This specifies which interrupt line the device
may use. IRQ conflicts used to be a common problem when adding expansion boards,
but the Plug-and-Play specification has removed this headache in most cases.
ISA (Industry Standard Architecture)
ISA is a standard bus (computer interconnection) architecture that is associated with
the IBM AT motherboard. It allows 16 bits at a time to flow between the motherboard
circuitry and an expansion slot card and its associated device(s). Also see EISA and
MCA.
LAN (Local Area Network)
A computer network that covers a relatively smaller area, such as in a building or an
enterprise. It is made up of servers, workstations, shared resources, a network operat-
ing system and a communications link. These individual PCs and devices on a LAN are
known as "nodes", and are connected by cables to access data and devices anywhere on
the LAN, so that many users can share expensive devices and data.
