Definitions

Author  An author is a person or program that writes or generates WML, WMLScript or other content.

Client  A device (or application) that initiates a request for a connection with a server.

Content  Subject matter (data) stored or generated at an origin server. Content is typically displayed or interpreted by a user agent in response to a user request.

Content Encoding  When used as a verb, content encoding indicates the act of converting content from one format to another. Typically the resulting format requires less physical space than the original, is easier to process or store and/or is encrypted. When used as a noun, content encoding specifies a particular format or encoding standard or process.

Content Format  Actual representation of content.

Device  A network entity that is capable of sending and receiving packets of information and has a unique device address. A device can act as both a client or a server within a given context or across multiple contexts. For example, a device can service a number of clients (as a server) while being a client to another server.

JavaScript  A de facto standard language that can be used to add dynamic behaviour to HTML documents. JavaScript is one of the originating technologies of ECMAScript.

Man-Machine Interface  A synonym for user interface.

Origin Server  The server on which a given resource resides or is to be created. Often referred to as a web server or an HTTP server.

Resource  A network data object or service that can be identified by a URI or URL. Resources may be available in multiple representations (e.g., multiple languages, data formats, size and resolutions) or vary in other ways.

Server  A device (or application) that passively waits for connection requests from one or more clients. A server may accept or reject a connection request from a client.

Terminal  A device providing the user with user agent capabilities, including the ability to request and receive information. Also called a mobile terminal or mobile station.

User  A user is a person who interacts with a user agent to view, hear, or otherwise use a resource.

User Agent  A user agent is any software or device that interprets WML, WMLScript, WTAI or other resources. This may include textual browsers, voice browsers, search engines, etc.

WMLScript  A scripting language used to program the mobile device. WMLScript is based on ECMAScript and loosely based on the JavaScript scripting languages.
