with setting standards for computers and communications.
Infrastructure
mode
A client setting providing connectivity to an AP. As compared to Ad-Hoc mode,
whereby PCs communicate directly with each other, clients set in Infrastructure
Mode all pass data through a central AP. The AP not only mediates wireless
network traffic in the immediate neighborhood, but also provides communication
with the wired network. See Ad-Hoc and AP.
I/O
The term used to describe any operation, program or device that transfers data to
or from a computer.
Internet
appliance
A computer that is intended primarily for Internet access, is simple to set up and
usually does not support installation of third-party software. These computers
generally offer customized web browsing, touch-screen navigation, e-mail
services, entertainment and personal information management applications.
IP
A set of rules used to send and receive messages at the Internet address level.
IP (Internet
Protocol)
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
IPX, short for Internetwork Packet Exchange, 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. Sequenced Packet
Exchange, SPX, 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.
ISA
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 ISA has been replaced by PCI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.
ISDN
A type of broadband Internet connection that provides digital service from the
customer's premises to the dial-up telephone network. ISDN uses standard POTS
copper wiring to deliver voice, data or video.
ISO Network
Model
A network model developed by the International Standards Organization (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, Transport, Session,
