Short for Extensible Markup Language Hypertext Transfer Protocol, a set of APIs that enables XML, HTML or binary data to be transmitted to and from Web servers over the Internet using HTTP. An advantage of XMLHTTP is that when files that are ASPs or CGI programs are queried from the server, the XMLHTTP object continuously queries the server transparently to retrieve the latest information without the user having to repeatedly refresh the browser. XMLHTTP enables streamed content through DHMTL rather than ActiveX controls or Java applets.
- XML data island
Blocks (called islands) of Extensible Markup Language (XML) embedded in an HTML document. Microsoft Internet Explorer 5.0 and newer versions support embedding the XML data inside HTML pages. XML data islands can be accessed from client-side scripts or directly to bound to HTML elements.
Short for Extensible Messaging and Presence Protocol, an open, XML-based protocol for server-to-server near-real-time extensible instant messaging and presence. XMPP is a rival protocol to SIMPLE. XMPP also is known as the Jabber protocol because Jabber is based on XMPP. Jabber is not, however, the only instant messaging application that relies on XMPP.
Stands for Extended Memory Specification, a procedure developed jointly by AST Research, Intel Corporation, Lotus Development, and Microsoft Corporation for using extended memory and DOS’s high memory area, a 64K block just above 1MB.
