Infrastructure Basic Service Set

A term used to describe a Basic Service Set with an access point at the helm.

See also Basic Service Set (BSS).

Instant Message (IM)

An application that provides the ability for end-uses to see whether a chosen friend or co-worker is connected to the Internet; and, if so, to exchange messages with them. Instant messaging differs from ordinary email in the immediacy of the message exchange. IM also makes a continued exchange simpler than sending emails back and forth.

Institute of Electrical and Electronic Engineers (IEEE)

An international professional organization for electrical and electronics engineers, with formal links with the International Organization for Standardization (more commonly known as the "ISO"). This nonprofit organization develops, defines, and reviews standards within the electronics and computer science industries and is the standards body responsible for the 802.11 series of specifications.

Integrated Services Digital Network (ISDN)

Because our circuit-switched telephone system has difficulties handling large quantities of data, in 1984 the ISDN specification was released to allow for wide-bandwidth digital transmission using the telephone system's existing copper telephone wiring. Under ISDN, a phone call can transfer 64 kilobits of digital data per second.

International Mobile Telecommunications-2000

See also IMT-2000 DS (International Mobile Telecommunications-2000 Direct Spread).

See also IMT-2000 MC (International Mobile Telecommunications-2000 MultiCarrier).

International Organization for Standardization

See ISO.

International Telecommunications Union (ITU)

The formal name given to an international organization within which governments and the private sector coordinate global telecom networks and services. Although the ITU doesn't have the power to set standards, if its members agree upon a standard, that standard effectively becomes a world standard. The ITU consists of three major sectors: The Radiocommunication Sector (ITU-R); the Telecommunication Standardization Sector (ITU-T); and the Telecommunication Development Sector (ITU-D).

Internet

A term used to refer to a global decentralized network of computers that exchange data. Each host computer on the Internet is independent and can opt in and out of the various Internet services it uses and/or offers to the global Internet community.

Internet Engineering Task Force (IETF)

This is the formal name given to the protocol engineering and development arm of the Internet. For instance, the IETF defines standard Internet operating protocols such as the TCP/IP suite of protocols. The Internet Society Internet Architecture Board (IAB) supervises the IETF and its members are drawn from the IAB's membership. Standards are expressed in the form of "Requests for Comments" (RFCs).

IP Address

A 32-bit binary number that uniquely identifies a host (computer) connected to the Internet or to other Internet hosts, for the purposes of communication through the transfer of data packets.

Internet Engineering Task Force (IETF)

The main standards body responsible for establishing internetworking protocols. The IETF is an open international body concerned with the evolution of Internet architecture and the operation of the Internet. The IETF is open to any interested individual.

Internet Message Access Protocol (IMAP)

A standard protocol that provides a means of managing email messages on a remote server. Although IMAP is similar to the Post Office Protocol (POP), it offers more options than POP, including the ability to download message headers, create multi-user mailboxes, and build server-based storage folders.

Internet Protocol (IP)

The most widely used method for transporting data within and between communications networks is IP. This middle level protocol can interact with a variety of different lower layer carriers such as Ethernet, Wi-Fi, ATM and SONET. IP is as useful for the growing field of intranets (networks internal to an enterprise or organization and not connected to the outside world; e.g. a network used for classified processing) as it is for the geographically distributed, highly heterogeneous Internet. In more detail, IP provides a connectionless, unreliable, best-efforts packet delivery system. It does this by concentrating on only one task—to find a route for data packets. It doesn't care what's in the data packets, IP only wants to know the destination addresses.

Internet Service Provider (ISP)

This term refers to a company that provides its customers with access to the Internet and the World Wide Web via a user-friendly front end. Most ISPs have a network of servers (mail, news, Web, etc.), routers, and modems attached to a permanent, high-speed Internet "backbone" connection.

Internetwork Packet Exchange (IPX)

An IPX is a datagram or packet protocol that interconnects networks that use Novell's NetWare clients and servers. IPX works at the Network Layer and is connectionless, e.g. it doesn't require that a connection be maintained during an exchange of packets.

Intranet

This term refers to an internal TCP/IP-based network behind a firewall that allows only users within a specific enterprise to access it.

IntServ

Short for "integrated services, a set of IETF standards that cover how application services define their QoS requirements, how this information is made available to routers on a hop-by-hop basis, and ways of testing and validating that the contracted QoS is maintained. With the IntServ approach, each network element is required to identify the coordinated set of QoS control capabilities it provides in terms of the functions it performs, the information it requires, and the information it exports. IntServ-capable routers must classify packets based on a number of fields and maintain state information for each individual flow.

See also DiffServ.

See also Quality of Service (QoS).

IP

See also Internet Protocol (IP).

See also TCP/IP Suite.

IP Address

A 32-bit numeric identifier for a computer or device on a TCP/IP network is referred to as the "IP address." The IP address is written as four numbers separated by periods (commonly referred to as "dotted decimal"), with each 4-number set being within the range of zero to 255; i.e., 192.168.0.10 could be an IP address.

IPsec (Internet Protocol Security)

A framework for a set of protocols for security at the network or packet processing layer of network communication. IPsec is commonly used for implementing virtual private networks (VPNs) and for remote user access through dial-up connection to private networks.

IPX

See Internetwork Packet Exchange (IPX).

ISA (Industrial Standard Architecture)

This standard bus (a computer's electrical pathways along which signals are sent) architecture allows 16 bits at a time to flow between the motherboard circuitry and an expansion slot card and its associated device(s).

ISDN

See Integrated Services Digital Network (ISDN).

ISM (Industrial, Scientific, and Medical) Band

A set of radio frequencies centered around 2.4 GHz that is universally acknowledged to be available for unlicensed use by wireless technologies. The ISM band is very attractive for wireless networking because it provides a part of the spectrum upon which vendors can base their products, and end-users do not have to obtain FCC licenses to operate the products.

ISO

From the Greek word for equal, it is the commonly used term used to refer to the International Organization for Standardization, an international organization composed of national standards bodies from more than 75 countries. ISO has defined numerous computer standards, but the most significant is perhaps OSI (Open Systems Interconnection), a standardized architecture for designing networks.

See also OSI (Open System Interconnection) Model.

ISP

See Internet Service Provider (ISP).

ITU

See International Telecommunications Union (ITU).
