... WAP Architecture is divided into several layers.
WMLScript allows code to be built into files %����
The WTP runs on top of a datagram service, such as User Datagram Protocol (UDP) and is part of the standard suite of TCP/IP protocols used to provide a simplified protocol suitable for low bandwidth wireless stations.Wireless Transport Layer Security (WTLS). This is accomplished by adapting the transport layer to specific /Height 150 The WAP Protocols cover both the application (WAE), and the underlying transport layers (WSP and WTP, WTLS, and WDP). ��@����PL�;��PD �'A�t0�B��=�Ќ3CmA�\KCQk����q�h��Q�t�F�tmG܅!���I

An open, global specification that empowers mobile users with wireless devices to easily access and interact with internet information and services instantly. The structure and design of the WAP is in layered fashion, such that it is extensible, flexible and scalable. possible editors are: Notepad, TextPad, Emacs, SynEdit (for Java, Perl & PHP).

Wireless Application Protocol (WAP) Empowers mobile users with wireless devices to easily access and interact with information and services. It provides a scalable and extensible environment for application development of mobile; ii.

Explain the architecture of WAP technology. The WDP presents a consistent data format to the higher layers of the WAP protocol stack, thereby offering the advantage of bearer independence to application developers.Each of these layers provides a well-defined interface to the layer above it. This comparison is often cited by the WAP Forum and it helps to understand the architecture (WAP Forum, 2000a). A WML deck consists of one or several
