gain sharing
Describes a contract that defines the vendor's contribution to the customer in terms of specific benefits to the customer's business. Such a contract also defines the payment the customer will make according to the vendor's performance in delivering those business benefits. Gain-sharing contracts require the development of a delivery paradigm that links a customer's business metrics to a vendor's IT solution. The key elements of this paradigm, in order, are:
- Business metric definition and selection
- Client metric benchmarking
- Development of key performance indicators
- Investment options evaluation
- Gain-sharing contract development
- Financial engineering
- Delivery of services
- Re-evaluation and adjustment of metrics
Galileo
A planned Global Positioning Satellite System (GPSS) of 30 low-earth orbit satellites backed by the European Union and the European Space Agency and originally due for commercial operation in 2008. Galileo was delayed by funding problems, because private enterprise had showed little interest. The European Parliament agreed with the Council of Europe in November 2007 to finance the deployment entirely from European Union funds, and after a validation phase due for completion in 2010, the service is now scheduled to go into operation in 2013. Galileo will complement the U.S. Government's GPS system, which ran into problems with development delays for replacement satellites. The Russian Global Navigation Satellite System (GLONASS) has been guaranteed funding through 2009 and is being expanded to provide worldwide coverage with the launch of additional satellites during 2009.
GAN (generic access network)
Previously known as unlicensed mobile access (UMA), this is a network architecture designed to support seamless connectivity between wide-area cellular networks, such as GSM/GPRS, and LAN technologies, such as Wi-Fi or Bluetooth – it is an example of fixed-mobile convergence. See also FMC.
gateway
- A computer that sits between different networks or applications. The gateway converts information, data or other communications from one protocol or format to another. A router may perform some of the functions of a gateway. An Internet gateway can transfer communications between an enterprise network and the Internet. Because enterprises often use protocols on their local-area networks (LANs) that differ from those of the Internet, a gateway will often act as a protocol converter so that users can send and receive communications over the Internet.
- A product or feature that uses proprietary techniques to link heterogeneous systems.
gateway server
A server designed to transform data streams to better match device capabilities. For example, Wireless Application Protocol (WAP) gateway servers convert HTML to Wireless Markup Language (WML) for wireless devices, and a number of products can reformat HTML for devices such as mobile phones and personal digital assistants (PDAs). Today, HTML-based servers predominate. While HTML can be made aware of a unique device requesting content, more often "shadow" Web server applications are created to draw off and reformat the native content.
gateway (transcoding) server
Server designed to transform data streams to better match device capabilities. For example, Wireless Application Protocol (WAP) gateway servers convert HTML to Wireless Markup Language (WML) for wireless devices, and a number of products can reformat HTML for devices such as mobile phones and PDAs. Today, HTML-based servers predominate. HTML can be made aware of a unique device requesting content; however, more often, "shadow" Web server applications are created to draw off and reformat native content.

Describes a technology as well as an existing satellite system for assessing the location of any compatible receiver unit, using satellites to provide 24-hour positioning information regardless of the weather. GPS works on the principle of triangulation; by knowing its distance from three or more satellites, the receiver can calculate its position. The term most commonly refers to the satellite constellation provided by the U.S. government for military and widespread civilian use. This system will be complemented and possibly superseded by the Galileo System of 30 satellites, backed by the European Union and the European Space Agency, which is due for commercial operation in 2013. Russia operates an equivalent GPS known as GLONASS. See also LBS.

groupware
Software that supports interpersonal processes and the objects with which people commonly work. Groupware was originally coined to describe a new class of applications designed to provide electronic support for groups of individuals working together toward a common goal. The term has been applied to applications ranging from unstructured electronic mail to rigorously structured workflow systems. Groupware is more useful as a concept when it is broken down into three major stages: communication, coordination and cooperation. In this light, groupware applications can be viewed in terms of the degree of structure in the group interaction and in the complexity of that structure, and the rigor with which the activity itself is monitored.
GRX (GPRS roaming eXchange)

GUI (graphical user interface)
A graphics-based operating system interface that uses icons, menus and a mouse (to click on the icon or pull down the menus) to manage interaction with the system. Developed by Xerox, the GUI was popularized by the Apple Macintosh in the 1980s. At the time, Microsoft's operating system, MS-DOS, required the user to type specific commands, but the company's GUI, Microsoft Windows, is now the dominant user interface for personal computers (PCs).
A comprehensive GUI environment includes four components: a graphics library, a user interface toolkit, a user interface style guide and consistent applications. The graphics library provides a high-level graphics programming interface. The user interface toolkit, built on top of the graphics library, provides application programs with mechanisms for creating and managing the dialog elements of the windows, icons, menus, pointers and scroll bars (WIMPS) interface.
The user interface style guide specifies how applications should employ the dialog elements to present a consistent, easy-to-use environment (i.e., "look and feel") to the user. Application program conformance with a single user interface style is the primary determinant of ease of learning and use, and thus, of application effectiveness and user productivity.
H
hand-off
Process of transferring a mobile telephone call from one cell to another without dropping the call. Cellular users may traverse several cells during a conversation, sometimes requiring a high-speed handoff in a moving vehicle. A soft handoff entails establishing a second radio link with the mobile device before the first link is severed.
haptics
The use of tactile interfaces (for example, vibration or pressure) to provide touch or force feedback as part of the user interface.
hardware and software maintenance services
Maintenance services include both hardware maintenance and support services, and network software maintenance and support services.

Hardware support also includes online and telephone technical troubleshooting and assistance for setup, and all fee-based hardware warranty upgrades.
Sales of all parts are also included, exclusive of parts bundled with maintenance contracts. This segment includes only external customer spending on these services.
Software maintenance and support services include long-term and pay-as-you-go (incident-based) support contracts. Software support contracts include remote troubleshooting and support provided via the telephone and online channels, as well as installation assistance and basic usability assistance. In some cases, software support services may include new product installation services, installation of product updates, migrations for major releases of software and other types of proactive or reactive on-site services. Software products and technologies covered under this category include operating systems and infrastructure software. Software support services do not include the purchase of subscriptions that provide entitlement and rights to use future minor versions (point releases) or future major releases of software.
hardware maintenance and support services
These are preventive and remedial services that physically repair or optimize hardware, including basic installation, contract maintenance and per-incident repair – both on-site and at a centralized repair depot. Hardware support also includes telephone technical troubleshooting and assistance for setup and all fee-based hardware warranty upgrades. Exclusive of parts bundled into maintenance contracts, sales of all parts used to repair high-tech equipment in carry-in, mail-in or per-incident on-site delivery models, or purchased by the internal staff to perform the repair, are included.
The segments covered in the hardware maintenance and support services are defined in the following sections. This segmentation maps to Gartner's high-level segmentation for computing and telecom hardware products.

When no clear HCM strategy is in place, business leaders formulate departmental plans and adopt the technologies they feel they need to support individual and group responsibilities for enterprise performance.
HRMS (human resource management system)
Business applications for the management of HR-related transactions, best practices and enterprise reporting. Functions typically include core HR tracking, payroll and benefits. The scope is often extended to include recruiting, competency management, training, time management, performance management and self-service offerings.
HSDL (high-speed subscriber data line)
A local phone line with full-duplex TI capabilities. As corporate intranets grow, bigger "pipes" are needed to maintain network performance. The use of inverse multiplexers that combine multiple E1 circuits will be the best way to deliver that bandwidth between the user site and the carrier's central office. But the use of HSDL technology, as an alternative to inverse multiplexing of E1 circuits, will be a "dark horse" alternative to inverse multiplexing. Unlike inverse multiplexing, HSDL would require new support systems and maintenance procedures.
HSM (hierarchical storage management)
A storage management technology that can be used to identify inactive data and move it to near-line storage, automate the retrieval process, and migrate the data back to the primary storage medium and provide access for the user.
HTML (Hypertext Markup Language)
A document-formatting language derived from the Standard Generalized Markup Language (SGML), predominately used to create Web pages. The user's browser interprets HTML commands and formats the page layout, fonts and graphics on the screen. One of the more powerful features of HTML is its ability to create hyperlinks that enable the user to navigate between documents and files with a single click. HTTP is also sometimes used for messaging attachments as a way of supporting rich text formatting across product boundaries.
HTML that is generated by a program or service is considered "dynamically generated HTML," which has been confused with the Netscape and Microsoft technology called dynamic HTML (DHTML). These technologies offer client-side mechanisms for enhancing the capabilities of the Web browser and HTML documents. Dynamically generated HTML might contain DHTML, but they are not the same thing.
hub
A central device, usually in a star topology local-area network (LAN), to which each station's wiring is attached. Also called wiring concentrator. See intelligent hub.
HUD (head-up display)
A generic term for a display for which the user does not have to change his/her normal viewing position to see it. Personal head-up displays, for example, use optics mounted near the eye (on eyeglasses or a headset) to project the screen image. Although the physical display is small, the user has the illusion of watching a larger screen several feet away from the eye. This can be delivered as a display that blocks the user's vision or one that superimposes the computer image over the user's view of the real world.

ILTC (instructor-led training in the classroom)
The most common form of training. It uses lecture sessions and discussions to convey information. It is most commonly used for briefings and high-level education, but many commercial training courses also use this method.
IM (information management)
A method of using technology to collect, process and condense information with a goal of efficient management. Most large enterprises have a central IM function to facilitate this coordination. The primary technologies needed are contained in a set of modeling tools that either have or interface to a production-worthy repository where the information is stored and managed. The repository and tools must be capable of receiving information in a "top-down," "bottom-up" or "middle-out" evolutionary manner.
IM (instant messaging)
IM is a communications service in which short messages appear in pop-up screens as soon as they are received, thereby commanding the recipient's immediate attention. Most IM services offer presence information that indicates if the user is online and available to send and receive messages. These services also provide "buddy lists" that are groups of people who have been selected by the user for frequent access, as well as group-based chat services. Enterprise IM provides real-time message passing within private and public networks.
IMAP (Internet Message Access Protocol)
A protocol used to access e-mail or bulletin board messages from a (possibly shared) mail server. IMAP allows a client e-mail program to access remote message stores as if they were local. E-mail stored on an IMAP server can be manipulated from a workstation at the office, a desktop computer at home or a notebook computer while traveling, without requiring the transfer of messages or files back and forth between these computers. Details of the IMAP specification can be found at www.imap.org.

They provide extensive reporting and ad hoc query capabilities for sales management and finance, as well as "what if" modeling for financial analysis and plan design.
indirect channel
This is a channel through which independent third-party organizations resell products. In software markets, value-added resellers (VARs) and system integrators are two typical examples of the indirect channel:
- Dealer – This is a group of resellers including independent, regional and national organizations that normally sell products and services to the business, education and government sectors. Client meetings are typically scheduled ahead of time and are most often solicited by an outbound sales force. Dealers usually provide a low level of service, training and customer assistance, and other value-added services.
- Vendor-specific agent – This is a reseller dedicated to selling one vendor's products. The reseller store will carry the logo and products of that vendor but is not owned by the vendor (for example, some Xerox copier resellers in the U.S.).
- Indirect fax/phone/Web – This is a channel through which resellers sell a variety of products to end users through the use of the telephone, Web, fax, fax back and mail, including catalog sales. This is different from the direct fax/phone/Web channel in that the products are sold by resellers rather than direct from the vendor.
- VAR – This is a reseller that usually is not a storefront operation and typically acts as a consultant to clients. To qualify as a VAR, a reseller must have developed or configured some type of software package targeted at a particular market or offer significant integration expertise to the customer.
- VARs typically generate 40% or more of their revenue from custom products, service and support. VARs do not apply their label to the product and may not own the hardware or software.
- System integrators – These are system vendors and independent service providers that supply professional services to apply, migrate and integrate technology into business processes.
- Hosting and application service providers – These providers offer access to software over a network and may not include customization services.
information access with search
Information access technologies interact with applications such as document management, Web content management and other repositories to provide users with insight into their content. Increasingly, information access technology is also expected to include results from enterprise applications, such as CRM and legacy systems. In addition, it looks outside enterprises to access Internet-based content. Information access technology is often acquired as an embedded aspect of other applications, and portal, ECM, business application and other vendors frequently include enterprise search as part of their products.
The first and most mature information access technology is search engine technology. It is typically applied to unstructured data in document repositories. It includes both enterprise and desktop search. Increasingly, automatic categorization, creative visualization, content analytics and taxonomy support technologies are being added to this category.
information architecture
All the sources of information – including paper, graphics, video, speech and thought – that define the enterprise are represented by this layer of applications architecture. It also defines the sources and destinations of information, its flow through the enterprise, as well as the rules for persistence, security and ownership.
information (knowledge) assets
Information relevant to an enterprise's business function, including captured and tacit knowledge of employees, customers or business partners; data and information stored in highly-structured databases; data and information stored in textual form and in less-structured databases such as messages, e-mail, workflow content and spreadsheets; information stored in digital and paper documents; purchased content; and public content from the Internet or other sources.
information/data governance
Information governance is the specification of decision rights and an accountability framework to encourage desirable behavior in the valuation, creation, storage, use, archival and deletion of information. It includes the processes, roles, standards and metrics that ensure the effective and efficient use of information in enabling an organization to achieve its goals.
information delivery
- Reporting – Reporting provides the ability to create formatted and interactive reports, with highly scalable distribution and scheduling capabilities. In addition, BI platform vendors should handle a wide array of reporting styles (for example, financial, operational and performance dashboards).
- Dashboards – This subset of reporting includes the ability to publish formal, Web-based reports, with intuitive displays of information, including dials, gauges and traffic lights. These displays indicate the state of the performance metric compared with a goal or target value. Increasingly, dashboards are used to disseminate real-time data from operational applications.
- Ad hoc query – This capability, also known as self-service reporting, enables users to ask their own questions of the data, without relying on IT to create a report. In particular, the tools must have a robust semantic layer to allow users to navigate available data sources. In addition, these tools should offer query governance and auditing capabilities to ensure that queries perform well.
- Microsoft Office integration – In some cases, BI platforms are used as a middle tier to manage, secure and execute BI tasks, but Microsoft Office (particularly Excel) acts as the BI client. In these cases, it is vital that the BI vendor provides integration with Microsoft Office, including support for document formats, formulas, data "refresh" and pivot tables. Advanced integration includes cell locking and write-back.
infrastructure software
This segment includes AD and application integration and middleware (AIM) software, information management software, storage management software, IT operations management and security software, and other infrastructure software.
- Application development and AIM software services – The AD software market comprises tools that represent each phase of the software development life cycle (application life cycle management [ALM], design, construction, automated software quality and other AD software). The Application Infrastructure and Middleware market segment includes business process management (BPM)-enabling technologies, integration-enabling middleware, platform middleware, portals and Web 2.0 infrastructure, and various additional products grouped together as "other AIM." Integration-enabling middleware is software that enables independently designed applications, software components or services to work together, by supporting data consistency, composite application and multi-step process styles of integration.
- Information management software services – This software market is defined by Data Management and Integration software and includes Data Integration Tools, Data Quality Tools and Database Management Systems. The discipline of data integration comprises the practices, architectural techniques and tools for achieving the consistent access and delivery of data across the spectrum of data subject areas and data structure types in the enterprise to meet the data consumption requirements of all applications and business processes. Traditionally aligned with cleansing of customer data (names and addresses) in support of CRM-related activities, the tools have expanded well beyond such capabilities, and forward-thinking organizations are recognizing the relevance of these tools in other data domains. A database management system (DBMS) is a product used for the storage and organization of data that typically has defined formats and structures. DBMSs are categorized by their basic structures and, to some extent, by their use or deployment.
- Storage management software services – The storage management software market includes all software products that are sold as value-added options to run on a server, storage network device or storage device to aid in managing the device or managing and protecting the data. Storage management software represents all the tools needed to manage capacity, performance and availability of data stored on disks, tapes and optical devices, as well as the networking devices that the data may pass through.
- IT operations management and security software services – IT operations management (ITOM) software is intended to represent all the tools needed to manage the provisioning, capacity, performance and availability of the computing, networking and application environment. Security software is included to control and monitor access to internal and external IT resources.
- Other infrastructure software services – Other infrastructure software includes, but is not limited to, clustering and remote control software, directory servers, OS tools, Java license fees, mainframe infrastructure, and mobile and wireless infrastructure, as well as other infrastructure software.
- Operating system software – An OS is software that, after being loaded into the computer by an initial boot program, manages a computer's resources, controlling the flow of information into and from a main processor. OSs perform complex tasks, such as memory management, control of displays and other input/output peripheral devices, networking and file management, and other resource allocation functions between software and system components. The OS provides the foundation on which applications, middleware and other infrastructure components function. OS usually provides user interfaces, such as command-line shell and GUI, for interaction between user and computer. The four most common subcategories of operating systems include Linux, Unix, Windows and mainframe OS.
INSPECT
Gartner's iterative framework for planning and executing application change. The letters stand for: Inventory, Scope, Parse, Examine, Consider options, Tactical solutions.
integrated carrier
An entity that owns/operates both fixed-line and mobile network infrastructure and provides aforementioned services (fixed and mobile).
integrated software
A business software productivity program that incorporates a number of applications (typically word processing, database management, spreadsheet, graphics and communications) into one product, allowing data sharing between all or most modules.
integration
Integration services are detailed design and implementation services that link application functionality (custom software or package software) and/or data with each other or with the established or planned IT infrastructure. Specific activities might include project planning, project management, detailed design or implementation of application programming interfaces, Web services, or middleware systems.
integration appliances
An integration appliance can be regarded as a combination of hardware and software that fulfills a specific integration purpose, such as enabling the partially predefined integration of certain applications together with new ones. It is not uncommon to see packaged integration, packaged processes, and SOA governance mechanisms and technologies alongside traditional appliance technologies, such as acceleration, transformation, XML parsing and security features, such as firewalls and packet inspection. An appliance can be regarded as one type of deployment mechanism, along with the more traditional packaged software, SaaS and hosted models.
intellectual property
Intellectual property traditionally includes assets that are protected through regulatory methods such as patents, copyrights and regulatory licenses; however, this protection is being expanded to include software and business processes when these can be demonstrated to be original, novel and non-obvious. Customer intelligence and business intelligence may be considered intellectual "property" by its owner, depending on its value to enterprise competitiveness and its integration into business processes.
Internet
A loose confederation of independent yet interconnected networks that use the Transmission Control Protocol/Internet Protocol (TCP/IP) protocols for communications. The Internet evolved from research done during the 1960s on a network called the ARPANet. It provides universal connectivity and three levels of network services: connectionless packet delivery, full-duplex stream delivery, and application-level services.
Internet telephony
Term used to describe packetized IP voice traffic sent over the Internet (as distinct from a private or managed IP telecommunications infrastructure). When used to enable Internet telephony from a PC, it requires client software on the PC such as Skype, plus a broadband connection with minimal latency. See also IP telephony and VoIP.
interoperability
The ability for a device from one manufacturer to work with one from another.
intranet
A network internal to an enterprise that uses the same methodology and techniques as the Internet. It is not necessarily connected to the Internet and is commonly secured from it using firewalls. Intranets often use an organization's local-area networks (LANs) or wide-area networks (WANs). Services include Web sites, collaboration, workflow and messaging services, and applications development.
I/O (input/output)
The activity of sending information to or from peripheral devices, terminals, direct-access storage devices (DASDs), tape drives and printers. Physical I/O performance lags behind that of memory and logical technologies.
I/O bound
Refers to programs with a large number of I/O (input/output) operations, which slow the central processing unit (CPU).
I/O channel
Equipment forming part of the input/output system of a computer. Under the control of input/output (I/O) commands, the channel transfers blocks of data between main storage and peripherals.
IP (Internet Protocol)
Transmission Control Protocol/Internet Protocol (TCP/IP) tracks the address of nodes, routes outgoing messages, and recognizes incoming messages. Current networks consist of several protocols, including IP, Internetwork Packet Exchange (IPX), DECnet, AppleTalk, Open Systems Interconnection (OSI) and LLC2. This wide diversity of protocols results from application suites that assume their own particular protocols. Collapse from this wide variety is inevitable, but users will only be able to reduce this diversity, not eliminate it. Most users will collapse networks into two main protocols: IP and IPX. Installed-base applications and the pain of change will prevent a total reduction to a single backbone protocol.
IPA (integrated publishing architecture)
A Gartner concept that defines the creation, assembly and production functions to support the complete document life cycle. Creation includes document component modeling, authoring, content identification, revision, review and approval; assembly includes document aggregation modeling, on-demand document construction and database interchange; and production includes composition, layout and file formatting for multiple communication channels.
IP address (Internet Protocol address)
A unique number assigned by an Internet authority that identifies a computer on the Internet. The number consists of four groups of numbers between 0 and 255, separated by periods (dots). For example, 195.112.56.75 is an IP address.
IP Centrex platforms
IP Centrex platforms offer a broad range of PBX replacement and new services. These products typically work with a variety of end-user devices and interfaces, including analog and digital phones, IP desktop phones, PDAs and mobile phones, all of which are widely used in enterprises.
These platforms offer a wide variety of enhanced features, such as: unified messaging (including visual voice mail); click to talk; enhanced find-me/follow-me capabilities; Microsoft Outlook integration, with "click to call" features; the ability to return calls and voice mail from a browser; Web-based call management to monitor and control service features and capabilities; automatic call distribution capabilities; selective call acceptance; collaborative applications; presence management; and instant messaging.
IP datacasting
IP datacasting uses DVB-H technology to transmit digital multimedia data to mobile devices in the form of IP datagrams. Content can be optimized for mobile handsets by adapting it to their small screens.
IP-enabled PBX
A customer-premises telephone switching system that has native IP switching and a TDM switching matrix, each delivering call-processing features and functions transparently between internal extensions (stations), whether the endpoint is an IP or traditional device. Typically, an IP-enabled product starts life as a traditional PBX, but is further developed to include IP capabilities. The traditional TDM switching matrix remains a part of the architecture, but a server-based processor capable of delivering voice traffic via packet switching has been added.
IP-enabled PBX/KTS IP extension line
A line attached to an IP-enabled PBX phone system that terminates with an IP phone or voice endpoint.
IP-enabled PBX/KTS traditional extension line
A line attached to an IP-enabled PBX phone system that terminates with a digital or an analog (non-IP) phone set.
IP extension line
A line that terminates with an IP phone or voice endpoint that was shipped, installed, and in use and attached to an IP-enabled PBX or IP-PBX phone system.
IP multimedia subsystem session control layer
IP Multimedia Subsystem (IMS) is a standardized, open architecture based on SIP and the Diameter authentication, authorization and accounting (AAA) protocol. IMS defines how applications and services are delivered to customers, regardless of which network they run on. It separates session control from the actual applications for maximum flexibility, and can be used for centralized user profiles. It helps carriers to control sessions and provides the ability to charge for applications.
In addition to voice switching, control and applications carriers are also deploying data and video control layers, and IMS multimedia. They are also building more nimble and agnostic service layers with architectures such as NG service delivery platforms (SDPs). This area includes, for example, deployments of IP television (IPTV) and video overlays, as well as service enablers such as presence, instant messaging (IM)/chat, third-party exposure and application stores. The area is often associated with Telco 2.0.
IP-PBX
A LAN-based IP switching communications system that provides telephony functions employing voice IP endpoint connectivity. At least 95% of lines on pure IP PBX systems must terminate with IP voice endpoints.
IP seat license
A telephony seat that is in use and part of an IP-enabled PBX or IP-PBX phone system that terminates with an IP phone.
IPTV
IPTV refers to the use of a carrier-based managed IP broadband network to deliver television and video content services to an end user's TV set via a set-top box (STB), with picture quality at least equivalent to existing pay-TV and free-to-air services. Content delivered over the Internet or only to a PC is excluded from our definition of the IPTV market. Our definition of IPTV includes all video content – whether broadcast-style pay-TV, video-on-demand (VOD) or other interactive video services. IPTV customers can search channel guides and select programs through an electronic program guide (EPG) on their TV screen. EPGs have varying degrees of functionality, depending on the service provider.
The typical IPTV model involves both broadcast pay-TV and on-demand services. Most IPTV providers offer both, though it is multichannel pay-TV that remains the key selling point in most services – and that generates most of the revenue. As a result, many IPTV services still have a strong focus on competing in a like-for-like manner against existing pay-TV services such as cable TV and direct-to-home (DTH) satellite offerings, often with similar packages of channels. Although this will change as new functionality is made available to IPTV users, it means that multichannel TV will be the foundation of IPTV offerings for several years.
iPhone
Apple's mobile device that combines an iPod music and video player, mobile phone and Internet browser capability in a handheld unit with a touchscreen interface. An iPhone designed for EDGE cellular networks was launched in North America in June 2007 and in Europe in late 2007. A 3G-capable version was launched in July 2008.
IP-service control points
An IP-SCP is a carrier-grade application server using industry-standard hardware, operating systems, open standards and protocols. The application server normally incorporates a real-time database and service logic execution functionality (also known as call triggers via a service switching point [SSP]), facilitating applications. The application server includes provisioning interfaces.
IP telephony
The term used for LAN-attached telephony systems and the associated telephone handsets (that is, the IP version of the PBX). More specifically, IP telephony involves the delivery of the telephony application (for example, call setup and teardown, and telephony features) over IP, instead of using circuit-switched or other modalities. IP telephony is not the same as VoIP or Internet telephony, although the terms are commonly (and erroneously) used interchangeably. See also Internet telephony and VoIP.
IRD (integrated receiver decoder)
Official name for the signal reception system that receives and converts modulated signals back into their original format suitable for presentation to an end-user device or display. IRDs typically contain a built-in decoder for unscrambling subscription TV programming channels. It is also known as a satellite receiver or satellite set-top box.
irDA (Infrared Data Association)
Maintains a standard for infrared data transmission (up to 4 Mbps). Because this technology's cost is extremely low, it is now embedded in many consumer electronic devices (for example, laptop computers and handheld devices, such as PDAs and cellular phones).
IRR (internal rate of return)
IRR analysis determines the interest rate and then compares this rate to the "risk-adjusted rate of return."
ISDN (Integrated Services Digital Network)
A technical standard and design philosophy for digital networks. ISDN provides high-speed, high-bandwidth channels to every subscribers on the public switched telephone network, achieving end-to-end digital functions with standard equipment interface devices. ISDN networks enable a variety of mixed digital transmission services to be accommodated at a single interface.
ISO (International Organization for Standardization)
A voluntary, nontreaty organization established in 1949, as a technical agency of the United Nations, to promote international standardization in a broad range of industries. ISO's Open Systems Interconnection (OSI) Reference Model establishes guidelines for network architectures.
ISO (Internet sales outlet)
A third-party Web site that attracts visitors looking to buy goods or services. ISOs make money by selling links or ads that lead directly to Web merchant sites or by selling products or services on behalf of Web merchants.
ISO 9000
The international standard for quality control. It is also known as BS5750 and EN29001. The three standards are identical, but they are numbered and published differently by different standards bodies. The worldwide standard is published by the International Organization for Standardization (ISO), and is the one generally referenced. ISO 9000 is a generic standard that any enterprise or individual department can use. It is not specific to the IT industry. The standard is subdivided into three – ISO 9001, ISO 9002 and ISO 9003. Enterprises use some or all of the parts, depending on the nature of their business. Any enterprise can claim that it complies with ISO 9000. To make the claim credible, an external assessor from an accreditation body must evaluate the enterprise's quality system. ISO 9000 certification does not guarantee quality; it guarantees consistency of approach.
ISP (Internet service provider)
A company that provides Internet access to its customers. The majority of ISPs are too small to purchase access directly from the network access point (NAP), and instead buy pieces of bandwidth that are available from larger ISPs. Access to the Internet can be provided either via modem or by direct connection, which offers far higher speeds.
Internet service providers are different from online services, although these services sometimes also provide access to the Internet. Online services provide access to exclusive content, databases and online discussion forums that are not available outside the service.
ISV (independent software vendor)
A software producer that is not owned or controlled by a hardware manufacturer; a company whose primary function is to distribute software. Hardware manufacturers that distribute software (such as IBM and Unisys) are not ISVs, nor are users (such as banks) that may also sell software products.
ISVs typically offer products that the primary vendor (i.e., IBM) does not offer, allowing clients of that vendor to round out their software needs. ISVs create price competition and also increase the pace of technology innovation in their markets.
IT (information technology)
This is the common term for the entire spectrum of technologies for information processing, including software, hardware, communications technologies and related services. In general, IT does not include embedded technologies that do not generate data for enterprise use.
ITAM (IT asset management)
A systematic approach to managing IT assets, including information systems (IS) department staff, end users performing IT support, technology procurement teams, suppliers, facilities, hardware and software.

IT management
IT management services provide day-to-day management and operation of IT assets and processes. As such, they represent the core value components of ITO. IT management services are divided into three key subsegments: operations services (for IT infrastructure), application management services and help desk management services.
IT management services
Management services transfer all or part of the day-to-day management responsibility for a customer's network environment (including LAN hardware and software, WAN – voice and data – and voice network hardware and software) and, in some cases, the ownership of the technology or personnel assets, to an outside vendor. These services may include system operation or support, capacity planning, asset management, availability management, performance management, administration, security, remote monitoring, technical diagnostics/troubleshooting, configuration management, system repair management and generation of management reports. Network remote monitoring and management, and backup and recovery services, also fall into this category when some degree of management is included in the service.
ITOM (IT operations management) software
IT operations management (ITOM) software is intended to represent all the tools needed to manage the provisioning, capacity, performance and availability of the computing, networking and application environment. We divides the ITOM market into 10 major segmentsthat include DBMS, application management, availability and performance, event, fault and log management, network management, configuration management, IT services desk and IT help desk, asset management, job scheduling and other ITOM (which refers to output management software) for tools used to manage hardware peripherals, such as printers.
IT operations
The people and management processes associated with IT service management to deliver the right set of services at the right quality and at competitive costs for customers.
IT outsourcing (ITO)
Our IT outsourcing efforts focus on using external service providers to effectively deliver IT-enabled business process, application service and infrastructure solutions for business outcomes...
IT service desk (ITSD) and IT help desk
IT service desk (ITSD) products range from simple call tracking/trouble ticketing (aka "help desk" products) to broad suite solutions encompassing call management, incident management, problem management, IT change management, configuration/inventory repositories, request fulfillment and self-service portals. In their technical platform, ITSD products include knowledge management (knowledge search capability) and workflow engines (managing automated escalation and notification). The most-sophisticated products also may link to dominant brands of corporate portals, external workflow engines, procurement modules and HR systems, or include these as proprietary features. These products integrate with operations management systems for links to event alerts, additional inventory repositories, configuration information and remote control. Product suites must have native support for Web self-service, password automation and e-mail ("native" means that the vendor either has built its own component or has licensed an engine and built value around it). The products must integrate with a range of communications tools, from telephony components to Web chat.
Certain areas of ITSD product functionality address only portions of a given process. IT CM within the tool addresses only the governance (aka production change control) and not the change execution, such as application or software provisioning, patching, or automated configuration setting changes, managed by the CM category. Software code and version is a change execution activity delivered by programming teams during the development process using SCCM tools. However, releasing code into production comes under the CM category. IT change projects, such as coordinating people-intensive IT projects, are change planning activities delivered by PPM products. The self-service portal capability will provide knowledge search and the ability to request service and support; however, the execution of stand-alone automated restore, also called "self-healing" – in which the user or help desk personnel are not involved – is part of the CM category. Only products that are positioned as ITSDs are included in the ITSD category. Products positioned as portals, workflow platforms or integration brokers are tracked in the AIM category. The fraction of vendor revenue from customer support software, sold as "help desk," is tracked as CRM software.

Agency of the United Nations, headquartered in Geneva. The ITU is the body through which governments and the private sector coordinate global telecommunications networks and services.
IVR (interactive voice response)
A voice/call-processing option for improving call center functionality and integration. It enables callers to have more flexibility to access information or leave messages. Use of this option can "offload" call volume from agents to the IVR or improve load balancing by having agents handle recorded messages during slow periods. A slowly growing number of IVR developers are now using speech recognition in their applications.
