Ajax = Asynchronous JavaScript and XML

: it is a term that describes a new approach to using a number of existing technologies together, including the following: HTML or XHTML, Cascading Style Sheets, JavaScript, the Document Object Model, XML, XSLT, and the XMLHttpRequest object. When these technologies are combined in the Ajax model, Web applications are able to make quick, incremental updates to the user interface without reloading the entire browser page.

Ajax is also seen written in all capital letters (AJAX).

AJAX (Asynchronous JavaScript and XML) is a newly coined term for two powerful browser features that have been around for years, but were overlooked by many web developers until recently when applications such as Gmail, Google suggest, and Google Maps hit the streets.

The two features in question are that you can:

    * Make requests to the server without reloading the page

    * Parse and work with XML documents

XML = Extensible Markup Language 확장성 생성 언어

: a specification developed by the W3C. XML is a pared-down version of SGML, designed especially for Web documents. It allows designers to create their own customized tags, enabling the definition, transmission, validation, and interpretation of data between applications and between organizations.

하이퍼텍스트 생성 언어(HTML)를 대체할 목적으로 월드 와이드 웹 컨소시엄(WWW Consorsium)이라는 단체가 표준화 작업을 진행하고 있는 페이지 기술 언어. 보통 XML이라는 약어로 불린다. HTML에서 사용되는 연결(link) 기능 등을 확장함과 동시에 표준 범용 문서 생성 언어(SGML)를 인터넷용으로 최적화한 것으로 HTML과 SGML의 장점을 모두 가지도록 규정하였다. 마이크로소프트사는 XML을 바탕으로 한 푸시형(push type) 소프트웨어용의 정보 배포 형식(information distribution format)인 채널 정의 형식(CDF)을 규정하여, 인터넷 익스플로러 4.0에서 실현하고 있다.
