A

ACORD

Association for Cooperative Operations Research and Development

ACORD is the insurance industry's nonprofit standards developer, a resource for information about object technology, EDI, XML and electronic commerce in the United States and abroad.

Among other things, ACORD governs an XML based data model to provide an easy way to exchange data between insurance companies, insurance brokers, other insurance related firms and governments.

AJAX

Asynchronous JavaScript and XML

AJAX is a group of inter-related web development techniques used for creating interactive web applications.

A primary characteristic is the increased responsiveness and interactivity of web pages achieved by exchanging small amounts of data with the server "behind the scenes" so that entire web pages do not have to be reloaded each time there is a need to get data from the server. This is intended to increase the web page's interactivity, speed, functionality and usability.

ANSI

American National Standards Institute

ANSI is a private non-profit organization that oversees the development of voluntary consensus standards for products, services, processes, systems, and personnel in the United States. The organization also coordinates U.S. standards with international standards so that American products can be used worldwide. For example, standards make sure that people who own cameras can find the film they need for them anywhere around the globe.

API

Application Programming Interface

API is a source code interface that an operating system, library or service provides to support requests made by computer programs.

ASCII

IDE is a software application that provides comprehensive facilities to computer programmers for software development. An IDE normally consists of a source code editor, a compiler and/or interpreter, build automation tools, and (usually) a debugger. IDEs are designed to maximise programmer productivity by providing tightly-knit components with similar user interfaces, thus minimising the amount of mode switching the programmer must do comparing to loose, discrete collections of disparate development programs.

IDL

Interface Description Language

IDL is a specification language used to describe a software component's interface. IDLs describe an interface in a language-neutral way, enabling communication between software components that do not share a language – for example, between components written in C++ and components written in Java.

IDLs are commonly used in remote procedure call software. In these cases the machines at either end of the ""link"" may be using different operating systems and computer languages. IDLs offer a bridge between the two different systems.

IDREF

IFX

Interactive Financial Exchange

IFX is an XML specification for financial transactions such as bill presentment and payment, business to business and consumer to business banking (e.g.: balances, financial transaction information), payments and automated teller machine (ATM) communications.

IMEI

International Mobile Equipment Identifier

IMEI is a number unique to every GSM and UMTS mobile phone. It is usually found printed on the phone underneath the battery.

The IMEI number is used by the GSM network to identify valid devices and therefore can be used to stop a stolen phone from accessing the network. For example, if a mobile phone is stolen, the owner can call his or her network provider and instruct them to ""ban"" the phone using its IMEI number. This renders the phone useless, regardless of whether the phone's SIM is changed.
