Wireless Application Protocol (WAP) is a set of communication protocols for wireless devices, such as mobile phones and PDAs. It was designed to enable access to and exchange of information and services on the Internet. WAP is based on the Hypertext Markup Language (HTML), but it is a simplified version of HTML that is optimized for wireless devices. WAP is supported by 2.5G technology, which is a second-generation cellular technology that provides data rates of up to 115 kbps.
Hypertext Markup Language (HTML) is a markup language used to create web pages. It is a set of codes that tell a web browser how to display a web page. HTML is a very simple language, and it is easy to learn.

XML is a more powerful language than HTML, and it is used for a variety of purposes, such as creating data formats, exchanging data, and storing data.
