information management applications. An Internet appliance can be Wi-Fi
enabled or it can be connected via a cable to the local network.
IP (telephony). Technology that supports voice, data and video
transmission via IP-based LANs, WANs, and the Internet. This includes
VoIP (Voice over IP).
IP address. A 32-bit number that identifies each sender or receiver of
information that is sent across the Internet. An IP address has two parts: an
identifier of a particular network on the Internet and an identifier of the
particular device (which can be a server or a workstation) within that
network.
IPX-SPX
(Internet
Exchange). IPX is a networking protocol used by the Novell NetWare
operating systems. Like UDP/IP, IPX is a datagram protocol used for
connectionless communications. Higher-level protocols, such as SPX and
NCP, are used for additional error recovery services. SPX is a transport
layer protocol (layer 4 of the OSI Model) used in Novell Netware networks.
The SPX layer sits on top of the IPX layer (layer 3) and provides connection-
oriented services between two nodes on the network. SPX is used primarily
by client/server applications. Whereas the IPX protocol is similar to IP, SPX
is similar to TCP. Together, therefore, IPX-SPX provides connection services
similar to TCP/IP.
ISA (Industry Standard Architecture). A type of internal computer bus that
allows the addition of card-based components like modems and network
adapters. ISA has been replaced by PCI and is not very common anymore.
ISO Network Model (International Standards Organization). A network
model developed by the ISO that consists of seven different levels, or
layers. By standardizing these layers, and the interfaces in between,
different portions of a given protocol can be modified or changed as
technologies advance or systems requirements are altered. The seven
layers are:
•
Physical

Data Link

Network
