Understanding Data Transmission
Introduction
Data transmission involves converting information into a special code for secure and efficient communication. This process ensures data privacy and prevents unauthorized interpretation. Computers operate with digital signals, while standard telephone lines use analog signals. Modems bridge this gap by converting between these signal types.

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