xML
--- eXtensible Markup Language ---
A programming language/specification developed by the W3C. XML is a pared-down version of SGML, designed
especially for Web documents. It enables Web authors and designers to create their own customized tags to provide
functionality not available with HTML. For example, XML supports links that point to multiple documents, as opposed
to HTML links, which can reference just one destination each.
XML provides a more powerful set of tools for developing a new generation of Web applications:
- Database exchange
- Distribution of processing to clients
- Multiple views of data on the client
- Intelligent agents
- Management of document collections
Whether XML eventually supplants HTML as the standard Web formatting specification depends a lot on whether
it is supported by future Web browsers. So far, the only major browser vendor to endorse XML is Microsoft, which
has stated that XML will be supported in a future version of Internet Explorer.
x-modem --- An
error-correction protocol (see binary transfer protocol) used by the DOS application XMODEM and many other
communications programs. Xmodem using CRC (cyclical redundancy check), a means of detecting errors in transmissions
between modems or across wired serial links.
