1. Scope
The Wireless Application Protocol (WAP) is a result of the WAP Forum’s efforts to promote industry-wide specifications for technology useful in developing applications and services that operate over wireless communication networks. WAP specifies an application framework and network protocols for wireless devices such as mobile telephones, pagers, and personal digital assistants (PDAs). The specifications extend and leverage mobile networking technologies (such as digital data networking standards) and Internet technologies (such as XML, URLs, scripting, and various content formats). The effort is aimed at enabling operators, manufacturers, and content developers to meet the challenges in building advanced differentiated services and implementations in a fast and flexible manner.

4. Definitions and Abbreviations
4.1 Definitions
The following are terms and conventions used throughout this specification.
The key words « MUST », « MUST NOT », « REQUIRED », « SHALL », « SHALL NOT », « SHOULD », « SHOULD NOT », « RECOMMENDED », « MAY » and « OPTIONAL » in this document are to be interpreted as described in [RFC2119].
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.
5. Background
5.1 Motivation
WAP is positioned at the convergence of two rapidly evolving network technologies, wireless data and the Internet.
Both the wireless data market and the Internet are growing very quickly and are continuously reaching new customers. The explosive growth of the Internet has fuelled the creation of new and exciting information services.Most of the technology developed for the Internet has been designed for desktop and larger computers and medium to high bandwidth, generally reliable data networks. Mass-market, hand-held wireless devices present a more constrained computing environment compared to desktop computers. Because of fundamental limitations of power and form-factor, mass-market handheld devices tend to have:
•Less powerful CPUs,
•Less memory (ROM and RAM),
•Restricted power consumption,
•Smaller displays, and
•Different input devices (eg, a phone keypad).
