IDE
Integrated Device Electronics. An ATA specification for drive interface. This
is a common interface used primarily for hard drives and CD drives. This
interface is commonly integrated directly into the computer’s system board,
and it allows up to four drives to communicate simultaneously with the
computer. See also EIDE.
IP
Internet Protocol. The protocol governing how data is sent from one computer
to another on the Internet. See also IP Address and TCP/IP.
IP Address
Each computer on the Internet has at least one IP address that uniquely
identifies it from all other computers on the Internet. When you send or
receive data on the Internet, it contains both the sender's and receiver's
addresses. See also TCP/IP.
IPX
Internetwork packet eXchange. A networking protocol from Novell
®
that
interconnects networks that use Novell NetWare
®
clients and servers. See
also SPX and IPX/SPX.
IPX/SPX
Internetwork Packet eXchange (IPX)/Sequenced Packet eXchange (SPX). A
Novell network communications protocol that functions similarly to TCP/IP.
IRQ
Interrupt request. An electronic pathway assigned to a specific device so that
the device can communicate with the microprocessor. Each device
connection must be assigned an IRQ. For example, the first serial port in your
computer is typically assigned to IRQ4. Although two devices can share the
same IRQ assignment, you cannot operate both devices simultaneously.
ISA
Industry-Standard Architecture. A standard for IBM-compatible PCs that
extends the bus architecture to 16 bits. It also allows for bus mastering,
although only the first 16 MB of RAM are available for direct access. ISA is
sometimes referred to as AT bus architecture.
ISO
International Organization for Standardization. A voluntary organization
founded in 1946, comprised of the national standards organizations of many
countries. ISO determines international standards in many areas, including
computers and communications. ANSI is the American member of ISO.
