WAP, or wireless application protocol, is the standard capability that allows mobile phones to have Internet service. It is different than the Internet that is used on desktop computers because it allows the device to be completely wireless.
Through the years, the Internet grew to a point where it was booming. The Internet went from something that was only intended for the rich and technology savvy to something that was standard for all people to have. It started out on desktop and laptop computers, but mobile phones began to quickly adopt the practices of the Internet. Most mobile phones are equipped with Internet capabilities.
Traditional Internet cards that are used in notebook computers and homes are not meant to be carried around and jostled in a pocket. The Internet capabilities that are used on phones must be able to stand up to a lot of pressure; they must be able to function in a variety of environments. WAP allows these phones to connect to the Internet when there is any type of service around the phone, whether it is a cellular network or a signal from a wireless router.
