Understanding Wireless Application Protocol (WAP) and Types of Information Systems

Understanding Wireless Application Protocol (WAP)

What is WAP?

Wireless Application Protocol (WAP) is a technical standard for accessing information over a mobile wireless network. It enables mobile devices, like early cell phones, to display internet content efficiently.

How WAP Works

WAP operates through a three-tier model:

  1. Client: The mobile device running a WAP browser.
  2. Gateway: Translates WAP requests into standard web requests and vice versa.
  3. Origin Server: The web server hosting the content.
